OWC Mercury Accelsior Joins Other PCIe SSDs
OWC has released their first ever PCIe SSD, the Mercury Accelsior. The drive comes in four capacities, namely 120 GB, 240 GB, 480 GB and 960 GB. The lower two drives utilizes SandForce SF-2281 controllers while the upper two uses SF-2282 controllers. The maximum sequential read and write speeds for the Mercury Accelsior are 780 MB/s and 763 MB/s respectively.
OWC has been known to produce Mac-based drives and this one is no exception. The Accelsior boots with Mac OS X without the need for any drivers and is the first PCIe drive to do so. The Mercury Accelsior employs the same plug-in-play functionality on Windows-based computers.
Updating the capacities is easy with these drives as you don’t need to buy a whole new unit. Each Mercury Accelsior SSD contains two blades having their own SF controller and 24nm Toshiba Toggle-Mode MLC NAND. Getting higher storage means you only need to replace the blades. The 120 GB costs $360 while the 960 GB costs $2096. The blades should be much cheaper although OWC is yet to sell them. The drives are configured RAID 0 by default but can be changed to RAID 1 if desired.
