During CES 2012, the SSD Review got an early look at Other World Computing's (OWC) stackable PCIe SSD. The drive is connected through a PCI-Express 2.0 x4 interface and contains the Marvell 88SE9445 SATA 6Gb/s RAID controller. The stackable PCIe card is capable of holding four mPCIe cards, which can provide a total capacity of 2 TB when all four slots are filled. The mPCIe card contains either the LSI SandForce SF-2281 or SF-2282 controller and houses a total of eight Toshiba Toggle mode NAND flash memory (four on the front and four on the back). No pricing, availability, or performance information was provided during CES 2012 for OWC's PCIe SSD.
Mushkin joins the PCIe SSD race with its announcement of its 'Scorpion' PCIe SSD during CES 2012. Mushkin lists the Scorpion's performance at 1275 MB/s sequential read, 1500 MB/s sequential write, and 120,000 4K random write IOPS. The drive is connected through a PCI-Express 2.0 x4 interface and looks to utilize four LSI SandForce SF-2281 controllers in RAID, along with a single Marvell PCIe controller. It will be available in capacities of 240 GB, 480 GB, and 960 GB and is expected to be released in the first half of 2012.
