SSD Ranking: The Fastest Solid State Drives

A fast SSD is one of few hardware upgrades that has the potential to instantly improve how you experience your PC. This is especially true when switching from a mechanical hard drive, but switching between generations (i.e. from SATA to NVMe PCIe) can also be noticeable. SSDs are also key components in modern servers, vastly increasing throughput and efficiency, but we will mainly focus on the fastest consumer-oriented drives here.This list is not attempting to be the final word on SSD performance – just a rough guide to some of the top products on the market. It is primarily based on an average of sequential read and write speeds, but for performance and durability reasons, we generally prefer DRAM-equipped, MLC-based drives.

Note that SSD durability should not be measured like hard drives, in MTBF. Instead, a solid state drive’s life span is mainly determined by the number of times each block of cells can be written to before it wears out. SLC (single-level cell) NAND is more durable than MLC (multi-level cell), which in turn is more durable than TLC (triple-level cell) NAND. As of 2018, QLC drives are also available. Other than endurance, additional bits per cell also tend to affect performance negatively. Most consumer-oriented drives in 2018 use affordable TLC memory, whereas MLC is used in products aimed at the enthusiast or professional markets.

We’ll start this list with SATA drives, which are all bandwidth-limited compared to more modern interfaces such as NVMe PCI-express (M.2 or add-in cards).

Samsung 860 Pro1. Samsung 860 Pro

Available Capacities: 256GB – 4TB
Interface: SATA III 6Gbps
560MB/s read (256GB)
550MB/s write (256GB)

This list has been maintained for many years now and Samsung has been on top since late 2012, starting with the somewhat legendary 840 Pro. Today you need to move on from the ageing SATA interface to get noticeably better performance, but Samsung hasn’t stopped improving on its flagship SATA product. The result as of 2018 is the impressive 860 Pro, which not only performs exceptionally well, but has an endurance rating that is at least double that of its already excellent predecessor. And if previous Samsungs are an indication, the 300 TBW (terabytes written) rating for the 256 GB model up to 4,800 TBW for the 4 TB model (all use MLC NAND), might be conservative estimates. This, coupled with a 5-year warranty and great overall performance, makes the 860 Pro look very attractive indeed. If SATA is your only option, that is.

mx5002. Crucial MX500

Available Capacities: 250GB – 2TB
Interface: SATA 3 6Gbps
560MB/s read
510MB/s write

Crucial’s MX500 uses TLC NAND and is a more direct competitor to the Samsung 860 EVO than the 860 Pro. That said, it offers great performance at a very attractive price point and is available in capacities up to 2 TB. Like the 860 EVO it is also backed by a 5-year warranty, but its endurance rating is lower than both the 860 Pro and EVO. It starts at 100 TB for the 250 GB model and ranges up to 700 TB for the 2 TB model, which is still more than sufficient for the average user. The MX500 can compete with the 860 series in many areas, but rarely (if ever) surpass it. However, the price/performance ratio is excellent so this drive is a good choice for most SATA-limited systems.

Available Capacities: 128GB – 1TB
Interface: SATA III 6Gbps
550MB/s read (256GB)
520MB/s write (256GB)

The 860 Pro’s predecessor is still an excellent drive, but due to pricing and availability it is probably no longer the best option, but still good if you can find it at the right price. The 850 Pro series uses its own MEX controller in combination with 3D NAND (V-NAND) like its successor, which increases density without compromising performance. And it’s still ahead of today’s competition in many areas.

sandisk extreme pro4. SanDisk Extreme Pro

Available Capacities: 240GB – 960GB
Interface: SATA 3 6Gbps
550MB/s read
520MB/s write

SanDisk’s Extreme Pro is a direct successor to the Extreme II. Just like its predecessor the drive lives up to the expectations implied in the model name. It is slightly ahead of the Extreme II in most areas with sequential read speeds of 550 MB/s and write speeds of 520 MB/s (4K random read/write 100K/90K IOPS), although you will hardly notice the difference in everyday tasks.

More importantly though, SanDisk is confident enough to offer a 10-year warranty with the Extreme Pro – a unique offer in the consumer (or prosumer) segment. The 19nm MLC NAND is allegedly good for writing 22 GB of data per day for 10 years. Consequently, when this drive finally wears out in the average system built today, the SATA interface will be long since obsolete. The Extreme Pro is rather old by now, but then again so is the SATA interface and the drive should definitely be on your short list when evaluating high-end SATA 6 Gbps drives.

Taiwanese manufacturer ADATA may have a smaller marketing budget compared to tech giants such as Samsung and SanDisk, but it’s a company know for putting out well-performing, reliable products. The SU900 is perhaps not on par with the speediest SATA drives, but should be quick enough for most. Neither should reliability be an issue, since it uses MLC (3D) NAND and ships with a 5-year warranty.

The 860 EVO is Samsung’s follow-up of its incredibly successful 850 EVO. Do note that the difference between these two will be very slim due to the aforementioned interface constraints, but that matters little as the 860 EVO will eventually replace its predecessor in this price range. And it will likely still be a great choice given Samsung’s reliability record.

It performs very well considering it’s a TLC-based SSD. Moreover it offers excellent endurance numbers at precisely half those of the 860 Pro at equivalent capacities (which is still much better than most competitors), as well as a 5-year warranty.

Neutron XT7. OCZ Vector 180

Available Capacities: 120GB – 960GB
550MB/s read
530MB/s write

As you may have noticed, there are plenty of older products in this list of SATA drives. The reason is something of a shortage of new SATA SSDs in the high-end (as in MLC) segment. So even though the Toshiba OCZ Vector 180 was released in 2015, it’s still an excellent option in 2018 and 2019.

The Vector 180 uses 19nm Toshiba MLC NAND in combination with an OCZ Barefoot controller (formerly Indilinx). It is not quite on par with Samsung’s top drives in terms of performance, but it’s close enough. Also, the warranty is a very attractive five years or 50GB of writes per day.

ssd3708. Transcend SSD370

Available Capacities: 120GB – 480GB
Interface: SATA 3 6GBps
560MB/s read (256GB and up)
460MB/s write (512GB and up)

The SSD370 uses a Transcend TS6500 controller (a rebranded Silicon Motion SM2246EN controller) with Micron 128Gbit 20nm MLC NAND. The random 4KB read reaches 75K IOPS and the random 4KB write goes up to 75K IOPS as well. Its incompressible sequential read performance is excellent, while write performance is not as great overall. However, the drive has other advantages than pure speed.

Transcend bundles it with a custom firmware which enables encryption. While DevSleep is supported, slumber power modes, particularly HIPM and DIPM, are not. The drive comes with a 3.5″ desktop adapter for older machines, as well the cloning utility SSD Scope. It also features “StaticDataRefresh”, which is similar to what other drives do to correct data errors due to cell degradation.

Available Capacities: 120GB – 480GB
Interface: SATA 3 6Gbps
550MB/s read
510MB/s write

The Extreme II from Flash storage-giant SanDisk delivers excellent performance at a reasonable price point. It’s a predecessor to the Extreme Pro (see above), and likewise pretty old but still going strong as of 2016. Its sequential read speeds of 550 MB/s and write speeds of 510 MB/s are complemented by very good random read/write figures as well (95K/78K IOPS). SanDisk uses a controller from Marvell in this particlar line of SSDs – a chip with the fanciful designation 88SS9187 (also known as Monet) – with SanDisk’s own firmware and 19nm eX2 ABL MLC NAND (also from SanDisk), which makes for a particularly long-lasting combination according to several reports.

Adata sp92010. ADATA Premier Pro SP 920

Available Capacities: 128GB – 1TB
Interface: SATA 3 6Gbps
560 MB/s read (512 GB/1 TB)
500 MB/s write (512 GB/1 TB)

Another ageing but still excellent drive; here Adata uses a Marvell controller the designation 88SS9189. This is combined with synchronous 20m MLC NAND from Micron, which results in excellent performance in the higher-capacity variants of the SP 920. The drive is available in capacities ranging from 128 GB all the way up to 1 TB, with the 512 GB and 1 TB models offering the best performance (and most likely durability).

It is important to note that there’s a large reduction in sequential write performance in the lower-capacity variants: Sequential writes drop to 360 MB/s in the 256 GB model and a mere 180 MB/s in the 128 GB model. 4K read/write IOPS also take a hit, particularly in the 128 GB version of the SP 920. Consequently, we award the spot in the ranking to the 512GB/1TB models only.

1. Samsung 970 Pro

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 512GB, 1,024GB
3500MB/s read
2300MB/s write

If you want pinnacle performance and are willing to pay a bit more for it, then the Samsung 970 Pro is about as good as it gets in this form factor. Although in terms of everyday user experience, you would probably never be able to tell the difference between this an any of the other top contenders in this segment.

But an SSD is the sum of its parts, nothing more and nothing less. What sets the 970 Pro apart from many of its competitors (including the 970 EVO) is that it uses higher-quality MLC NAND, and will therefore last longer than its more affordable TLC counterparts. The endurance rating is 600 TBW (twice that of the comparable EVO) or five years (same as the EVO)

It will also perform better and more consistently. This is particularly noticeable in the random write area, with 500,000 IOPS (4K, QD32) in both available capacities.

2. Samsung 960 Pro

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 512 GB, 1 TB, 2 TB
3500MB/s read
2100MB/s write

Samsung stays in the lead with this blazing-fast m.2 PCIe drive. Like its predecessor, this m.2 drive supports 4 lanes of PCIe and uses NVMe for maximum bandwidth utilization and increased throughput. It uses Samsung’s own Polaris controller in combination with Samsung MLC V-NAND.

The 960 Pro supports TGC Opal and AES 256-bit data encryption. In the random read/write area, it delivers up to 440K IOPS for 4KB (QD32) random read and 330K IOPS for random writes (also 4KB/QD32). Reduce the queue depth to 1 and it still reaches an impressive 14K IOPS/50K IOPS read/write. These numbers, by the way, apply to the higher-capacity drives, while the 512 GB model is slightly slower.

Samsung offers a 5 year warranty with the 960 Pro as well as impressive endurance ratings of 1200 TB for the 2 TB model, 800 TB for the 1 TB drive and 400 TB for the 512 GB version.

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 250 GB, 500 TB, 1 TB
3200MB/s read
1900MB/s write (1 TB)

The strongest competitor to the 960 Pro in the M.2 enthusiast segment is probably Samsung’s own 960 Evo – the more affordable variant of the 960. It is not quite as fast, although the difference is small enough not to be noticeable in everyday usage scenarios.

It might be slightly more concerning for some users that the 960 Evo uses cheaper TLC NAND circuitry. This cuts the durability rating in half, from 400 TB to 200 TB for the popular 500 GB capacity. The warranty is also reduced from 5 to 3 years. This won’t be a problem for the vast majority of the intended users, but worth keeping in mind.

In terms of raw performance, the 960 Evo is rated at up to 380K/360K IOPS random read/writes (compared to 440K/360K for the Pro) in the largest capacities (QD32).

In short: This is probably the M.2 drive to get at the time of writing if the price/performance ratio is an issue at all, and if you don’t plan to write copious amounts of data to it too often.

Interface: PCIe Gen3 x4 NVMe
Available Capacities: 256 to 512 GB
2500MB/s read (512GB)
1500MB/s write (512GB)

Samsung’s previous-gen champion is still a speed demon compared to much of the current competition; this m.2 PCIe drive also uses NVMe, a Samsung UBX controller and V-NAND.

The 950 Pro also supports AES 256-bit data encryption and reaches up to 300K IOPS for 4KB random reads and 110K IOPS for 4KB random write. As for reliability, Samsung offers a 5 year limited warranty.

The only reported problem that has been reported, as far as we can tell, seems to be that the drive could get too hot due to the increased clock speeds, and thus you may encounter thermal throttling if you’re not ventilating the chips well.

While not as speedy as Samsung’s flagship, the Predator is still way faster than your standard SATA SSD. It’s flexible enough to use with every board thanks to the on-board OROM.

The HyperX Predator uses a Marvell 88SS9293 controller and Toshiba A19 MLC NAND. It can go up to 160K IOPS for 4KB random read and 119K IOPS for 4KB random write. Its mean time between failures is 1,000,000 hours. It also comes with a PCIe bracket since it’s aimed at desktop users who wish to upgrade. Finally, the warranty for this drive is 3 years.

According to some reports, it delivers lower battery life versus other Samsung drives, which makes it a less than ideal choice for laptops.

If you have a system capable of booting from an NVMe drive and the appropriate slot, Intel’s Optane 900p-series is quite possibly the best choice. The Optane series doesn’t use conventional NAND flash storage modules, but rather Intel’s next-gen 3D Xpoint memory. While this may not show in the drives’ raw sequential transfer performance compared to other high-end competitors, the latency numbers are significantly improved. As is the endurance rating, which is an incredible 10 full drive writes per day for 5 years. These characteristics mean that it’s well suited not only for enthusiast builds, but also for heavy-duty workstations.

In spite of its higher theoretical max. transfer rates (measured with ATTO, according to Corsair), we will rank the Neutron NX500 from Corsair below the Optane 900p because real-world performance is consistently below according to the reviews we’ve seen (links below). It’s apparently tough to compete with 3D Xpoint, but that doesn’t mean that the NX500 is a low-end product. Among the small number of consumer-oriented PCIe drives currently available in the add-in card form factor, it’s an attractive option given that the price point is reasonable compared to the Optane.

1400MB/s write
Random 4K Write: 30K IOPS

One of the main upsides of the Z-Drive is its ability to be used as a bootable device, making it a compelling choice for SANs, servers and workstations. Some of its other features are a 512MB cache, SAS compatibility and 3-year warranty.


Z-Drive P887. OCZ Z-Drive R2 E88

Interface: PCI-Express x8, 8 x SATA Controllers
Available Capacities: 512GB
Price: $9,149.00
1400MB/s read
1400MB/s write
Random 4K Write: 7200 IOPS

The main difference between this an the P88 is the usage of SLC NAND instead of MLC, which dramatically increases reliability and reduces wear. One of the main upsides of the Z-Drive is its ability to be used as a bootable device, making it a compelling choice for SANs, servers and workstations. It also consumes less power compared to hard drive arrays.


Z-Drive P8410. OCZ Z-Drive R3 P84

Interface: PCI-Express 2.0, X8 slot, half height, half length, 4 x SATA Controllers
Available Capacities: 300GB, 600GB, 1.2TB
Price: Contact OCZ
1000MB/s read
970MB/s write
Random 4K Write: 135K IOPS

The smaller footprint of the R3 should entice those who want faster storage for their compact servers. It also has a redesigned heatsink and a ‘Super-Cap’, which will let it complete write operations in the even of a power failure.

We’ve tried our best to compile the most comprehensive list of SSDs available and used this to create the lists you see above. Since there are new drives launched each month, we will update our list and ratings regularly. Also, if you think we’ve omitted something or need correction, don’t hesitate to leave a comment or contact us.

Production Processes

And unlike other parts such as a CPU/GPU, a smaller production process as measured in nanometers (nm), is not a strong selling point as it results in lower durability, all other things equal. worse  are not an improvement from a life-span perspective, but may decrease costs through manufacturing efficiency. However, for the average home or office user, durability is rarely an issue, since any SSD will most likely outlive the rest of a the computer by a wide margin. Just don’t rely on low-cost drives with cheap NAND in a server or other environment with a high continuous workload

  1. Quite an informative review.
    The quality of reviews have considerably increased since the first ones. Now they are realistic, and it is good, because in many sources all you can find is an annoying advertisement packing consumers with apparently deceiving information.
    The manufacturers are not in a hurry to produce something revolutionary new and ready as a final, standards-compliant, reliable product, most of the time they are going for profit, which delays the introduction of new technologies for many years. Server market may be considered an exception though, because deceiving the customers doesn’t work well there.
    This tendency is true for many other “modern” retail customer products now. For example, LED LCDs, which in fact have lower full spectrum reproduction range (yes, much lower than those with CCFL backlight) and some issues with flickering, but higher visual color reproduction range (just for eyes though).

  2. On the side note, you made it a bit tricky to pick up a desired avatar 😉

  3. Thanks vt! Actually a ton of research has gone into this from my colleague Glenn who wrote the piece and we plan to update it regularly. Hopefully it stays fresh for a couple of weeks… It’s a bit opportunistically based on “top speed” only, but that seemed logical considering this site’s name.

    And yes, something has to be done about those avatars 🙂

  4. Why aren’t the OCZ RevoDrive X2 or the original one listed on this site?

  5. @CMW: Yes, the RevoDrive X2 could probably be listed as drive #11 with 740/720MB/s reads/writes

  6. So many SSDs missing from this list it makes it obsolete from the get go..

  7. @Simon: That’s because the “get go” was a couple of months ago. It’s been updated.

  8. I’m still waiting for SLC NAND prices to go down, but they (the manufacturers) aren’t willing to cut them, while SLC chips have only 2x lower capacity.
    Spot price for 32 GBit MLC NAND – 5.41 $
    Spot price for 16 Gbit SLC NAND – 13.12 $

    That means that SLC NAND chips are unreasonably almost 2.42x more expensive than they could be. The manufacturers are way too greedy …

    Also, at this rate they are going to intentionally hinder more advanced SSD products with MRAM or FeRAM or other similar technology – just to get back the money and profit from their investments into NAND. That most likely means another 5 year without any good replacement to NAND. And no alternate to NAND SLC solutions, with the exception of DRAM SSDs, which are, of course, have greater potential for random I/O and bandwidth than any NAND product.

  9. Just wondering… Why are none of the SSD’s that OWC makes not included here?


  10. > The manufacturers are way too greedy …

    Welcome to capitalism! Enough people are willing to pay more so of course they’re going to charge as much as possible. This is always how the storage market goes.

    For example, it is pointless to have two different interfaces – SAS and SATA. Yet this is what allows them to stick it harder to people who will pay a lot more for just a little more speed. Same thing going all the way back to the early SCSI/IDE days.

  11. Does mushkin not even make the top 10? The numbers on their Chronos look good.

  12. Nice listing but its credibility suffers. I will never place Mushkin Chronos that high. Mushkin Chronos will never beat the OCZ Vertex 3 Max IOPS in benchmarks. There are lots of benchmarking sites that show that the numbers on Mushkin Chronos are the fake ones. OCZ is that low on the list only because they are telling the real numbers. The price of Mushkin is really low when comparing to the others and that makes is interesting product. But the failing performance numbers tell something about the manufacturers strategy…

    Reliable listing by performance should always base on the independent benchmarking not the numbers the manufacturers are telling.

  13. Great review of drives…
    manufacturer’s too greedy? Being a person who works for one the worlds largest companies and hearing this all the time, its just a stupid comment. People don’t realize the dollars spent and R&D in order to increase drive speeds, etc.. prices will come down, just give the companys time to make back some of their money. If you want a cheap SSD , buy a first gen drive, that the companies have droped the price because they are out of the “red”.

  14. “Being a person who works for one the worlds largest companies and hearing this all the time, its just a stupid comment.”
    Stupid for those who make money on that ? Maybe. But not for customers. There is no excuse for overblown prices on SLC memory chips, there is no excuse for hindering the progressive technologies just to make the most profit of the old and inefficient ones.

  15. Also, if you read the other comments, I already revealed the lies and deception all over the retail non-server SSD market, and I have really a lot of other facts worth mentioning regarding your REALLY stupid comment.

  16. @maggou,
    Thanks for the links. It certainly looks like a revision of the list is needed. I would personally not interpret the numbers as fake though, they are probably correct in synthetic benchmarks under optimal conditions. On the other hand, the Vertex 3 has had its share of firmware issues, but it is starting to look more and more solid and mature.

  17. funny how you missed the m4 with 0009 firmware cause its the fastest drive

  18. >>JimQ Said:
    Just wondering… Why are none of the SSD’s that OWC makes not included here?
    Perhaps because OWC doesn’t make anything at all, they just relabel the very stuff you are seeing above. Also because you most likely work there.


    Don’t be a money hungry bunch of pigs — seriously. OWC will pay you to review their crap, and tie an advertising contract to it.

    That’s no reason to review what you know is a relabeled product. There isn’t anything that’s “made to order” – assuming you don’t count a package type and the length of a cable!!

    Just review any of his other reviews — and then look at the amount of advertising he has on each of those, especially the dedicated Mac sites — where he lets those people keep product and takes out yearly contracts.

    That removes ALL the integrity that you are trying to establish. Don’t fall for that kind of scam – you’ll become as unworthy as the rest who do the same thing, vs. businesses that are growing on their own innovation, rather than by slime-ball tactics that also include pressure to remove posts made by those who criticize their customer service or sometimes crap products.

    They have some good stuff, and they also deceive where it is convenient. Don’t be part of that crowd that helps out a company that does that sort of thing. In the future it will become clear that you don’t want any association with this group. “Do No Evil” is not part of their mantra.

  20. @Bubu: Thanks for the tips! However, the RAM drives you link to are volatile and belong in their own separate category IMO.

  21. How is the Vertex 3 faster than the Mushkin? According to your dates the Mushkin has 10MB/s faster readrates or am I missing something? Would be great to know how you rate them exactly as I am about to purchase one of them…

  22. fusionIO’s ioDrive Octal is now available in 10.24tb

  23. Probably a bit off-topic –
    It is about AMD processors. They didn’t mention the fact that JFAMD DID know about the performance problems. I asked him several questions under different accounts, and the differences in his answers (lies) unambiguously pointed out the fact that he did know about the IPC problems, moreover he did know about the actual benchmarks and that it wouldn’t even meet the IPC of the older Intel processors. That was fun getting reaction out of him and getting the truth that way (he plainly reacted offensively at correct guesses, so by varying the questions and information given to him and watching his anger one could easily figure the exact benchmarks numbers with amazingly high precision).

  24. But well, he did one good thing – he led hundreds of PR idiots alongside, who have got their “expert” and “trustworthy” accounts compromised.

  25. @Alan: The difference between the SF-2281 drives is marginal, and the quoted speeds are not to be taken as gospel. In real-world tests the Vertex 3 Max IOPS generally beat most of the competition (MLC in the same form factor). But you have a point, this listing is due for an update.

  26. vt: Interesting thread. It’s hard to defend the indefensible…

  27. It’s a good list – but the speed is Sequential read and writes? Of course it’s the thing the manufacturers publish as they are impressive to see – in real use though Random read and writes are more important to the average user – IOPS more important in the Enterprise market…

  28. How about including the NEW OWC Mercury extreme Pro 6g 240gb with SANDFORCE 2282. I think they are the only company using this controller and tests have shown this is a very fast drive.

  29. […] may be priced in dollars but the spec remains the same: SSD Ranking: The Fastest Solid State Drives – April 2012 __________________ Wisdom is ofttimes nearer when we stoop than when we soar. – William […]

  30. Wow, apparently a walmart employee wrote the OCZ post.

    The Vertex 4 is slower then the vertex 3 in transferring data.

    Changing the controller has not paid off in real world applications.

    The consumer has turned into a clown, putting up with lies from the garbage Asus, and their failed Sata 3 marvell 9128, the joke of Intel building CPU’s for the outdated lga 1155.

    Seems not enough money has been made so the hardware has been shoved into reverse.

    What’s next for the fools, building systems on the LGA 775.

    The future is the entire point of upgrading not downgrading.

    The hardware industry needs a wake up call and needs to work on real Sata 3 controllers, building off the LGA 2011, and getting PCI-E 3.0 to actually work at 3.0 speed.

    Marvell the failures, the upgraded 9220, and 9230 are garbage.

    The 9128 and 9172 are absolute garbage and they should be sued for calling their junk Sata 3.

    Buy Asus and stay behind the times.

    Then we have Intel with Ivy Bridge, no real gains in per thread.

    Good thing the consumer just keeps buying garbage with no gains no real steps and using old hardware.

  31. @odiebugs: About the difference between the Vertex 3 and 4, yes, but it’s not quite that simple:

  32. In the enterprise section you missed listing the latest generation for OCZ, which has been out since October of last year

  33. Thanks Bruce! An update to the enterprise section is long overdue. Thanks for the reminder.

  34. This ADATA SSD drive should be number 2 after the Intel and number 1 if you compare to the price.

  35. How often can we expect this list to be updated?
    There are often changes going on.

    Nice list btw..but it’s almost half a year out of date now. 😛


  36. very informative..but i suggest adding corsair force gs to the list..its an upgraded version of corsair forc gt and its the fastest ssd that has been launched by corsair yet..the sandisk ultra also should be added

  37. Hello,
    We have RunCore SSD for our better server and there are no comparaison with HDD.
    We have buy our SSD on for our good price.
    What is the best SSD with PCIE for animation computer ?

    What is the most important in SSD for have the best result in Photoshop?

    Thank you

  38. @ADMIN, true, I do see nice gains in small R/W, 4k IOPS 120,000. Personally this drive is dependable and quick. Just in very large writes does it pace back a bit. A lot of people are having problems with some of the SSD’s, but they are mostly BIOS and windows problems that the consumer is blaming on the SSD. Now if Intel would stop crawling with the Ivy bridge-E so we can see the LGA 2011 to show its true colors, life would be better. If you update this review, you might have to add in the Corsair Force GS as top dog. Asus still putting that garbage Marvell 9128 on boards.

    Another proof that they are just getting the most $$$ out of outdated technologies (especially NAND MLC).

  40. […] even close. He would be better not wasting the extra money for the 840 pro and going with an 830 SSD Ranking: The Fastest Solid State Drives – October 2012 […]

  41. Prices seem wrong. In most cases the high
    price is misleading since many sites HAD and
    have the highest capacity items for about 1/2
    the price shown.

    For example, you show:
    “2. OCZ Vertex 4
    Available Capacities: 128GB – 512GB
    Price: From $399.00 to $1,899”

    but the prices 512GB were generally in the
    high US$400’s to low US$500’s. (The
    highest price Froogle found on 12/22 was
    $712.49, but I don’t know the high price
    in the past.)

  42. Thanks for the catch Mark, this has to be changed ASAP.

  43. hi, i have seen the Samsung 840 Pro but u dindt put the diferent transference rates that varies about the capacity… do the samsung are the same rate in all the capacities?


  44. Excellent article. Thanks. Perhaps you can answer another question. What is the difference in speed and quality between the SanDisk “Extreme” series SSD and their “Ultra Plus” product? Thanks

  45. I’ve actually found that since the 1.5.1 firmware update for the OCZ Vertex 4 it has made is MUCH! Faster. The usual speeds I get from it are about 550MB/s read and about 490MB/a write. This making it the 2nd fastest drive in the market.

  46. I just want to say that I appreciate you guys making this website a lot. I am building a fast computer coming out of high school and I wanted to find the best SSD’s that I can run my favorite games and OS on. Using your site, I will be able to make my search for one component that much easier, which is nice when you have to search for a lot of them. XD

    Thanks again!

  47. It’s all very well posting these’s speeds for SATA 3 users. But what about all us SATA 2 users. We need to know the speed/s we will get on SATA 2 using SATA 3 drives as well. Also raid speeds would help to.

    So lets see some tests here.

    I have 2 Crucial C300s 128GB in raid. On SATA 2

    Read is around R 530 MB/s and W 260 MB/s.

    As a single drive set up, R 267 MB/s and W 140 MB/s

  48. Another failure, this time at processor market – it looks like Haswell is going to be slower than its predecessor in memory-intensive applications. Not to mention that its caches may be actually slower as well in such applications. Probably defect Xeons (socket 2011) are the only good alternative for upgrading

  49. I am genuinely thankful to the owner of this website who has shared this enormous article at at this time.

  50. Would be great of this list can be updated. Lots of new ssds have come out.

  51. Drive measurements need to be done more accurately!

    All SSD results today are largely exaggerated, because the measurements are done using assisted, rather than directly oriented test techniques.

    Show us the *real* numbers, kids.

    Here are some real Sandisk numbers.

    Sequential Read : 360.335 MB/s
    Sequential Write : 169.426 MB/s
    Random Read 512KB : 341.851 MB/s
    Random Write 512KB : 166.551 MB/s
    Random Read 4KB (QD=1) : 24.467 MB/s [ 5973.3 IOPS]
    Random Write 4KB (QD=1) : 35.268 MB/s [ 8610.5 IOPS]
    Random Read 4KB (QD=32) : 204.754 MB/s [ 49988.7 IOPS]
    Random Write 4KB (QD=32) : 124.776 MB/s [ 30463.0 IOPS]

    Much less than they claim.

  52. What about the samsung 840 evo? And is this not being updated Anymore?

  53. Can you list a date when this was last updated? I love the simplicity and comprehensiveness of this list, but shouldn’t newer drives (such as revodrive 350) be on this list?

  54. Very useful post. Wanted to know more about ssd drives and brands. Thanls

  55. Hi there, just asking the FusionIO ioDrive Octal, the PCLe, can you use more than one drive, am building a nice gaming rig and what about it’s price? Do they allow exports because am in Africa, Kenya.

  56. Does the hexabus Foremay EC188 D-Series need more than one PCLe port?

  57. Just asking? Can you install Windows 8.x on those pcle drives, they are said to be servers and am not sure I can play bio shock infinite on them ( I hope I can) and I think I will go for the ioDrive octal 10tb version. It has better specs. Can the Asus x99 deluxe motherboard support 4 of those drives? for the fun of I have been living with HHDs till last year, I didn’t know such powerful drives existed. Your page has been very eye opening for me, thank you.

  58. I know HPE uses both NVDIMM and NVMe in their servers. May I know which other companies use a combination of these ?

  59. I just chucked out three solid state drives for one 3tb no state drive couldn’t be happier. Though I wouldn’t run it with Windows, Windows can’t see anything above 2tb imagine that.

  60. Which SSDs do not have Garbage collection mechanisms. Juts want to avoid them.

  61. I see here old and SATA based SSD’s. Among fastest are PCIE SSD’s such as Samsung 960 and Patriot Hellfire. Look for highest random read speed for practical speed.

  62. Bought Samsung 950 Pro, unfortunatelly it does not support my HP EliteBook 840 G3 with Product Number: L3C67AV.

  63. I do not realize the relation between the Interface (sata ii, sata iii,, pci,..) and the sdd speed. Anybody could explain I would appreciate that. Other question which is a bit off-topic , is it more economical to buy an external ssd and use thunderbolt 3(usb c) rather buying a macbook with larger ssd and exponentially pricier device?!
    Thank you

  64. Hi Ashkan, sorry for the late reply. The interface is important because it is may cap the speed of an SSDs (not
    mechanical drives, which are too slow). For example, most recent SATA III (6 Gbps) SSDs are capped by the interface, which is why you need to move to PCI Express (PCIe) to see an improvement. To confuse things a bit further, PCIe can be in regular PCIe card form factor or the smaller, on-board M.2 (the latter of which may also use a SATA interface, not to be confused with mSATA).

  65. Fusion IO drive octal is faster and larger than all these drives. 6.7GB/s read 3.9GB/s write 10TB

  66. IntelRIP corsair win

  67. SSD does not have garbage collection mechanism.

  68. Its true that Samsung is the best when it comes to consumer SSDs. I am using Samsung 860 Evo in my PC and it makes the Windows 10 load in only 2 seconds.
