OWC Releases Mercury Accelsior PCIe SSD@ 2012/04/19
The actual design is pretty interesting. OWC has opted to build the SSD out of two blades, each with their own controller and NAND running. The blades run in RAID 0 by default but they can also be configured in RAID 1 mode. Oftentimes everything is intergrated on one PCB but OWC's approach is different, and there is actually a big advantage todoing things this way. Using blades allows the capacity to be upgraded without buying a totally new card. OWC does not sell the blades separately yet, but manufacturing new blades should be somwhat cheaper than manufacturing the whole PCB, so down the road this could result in a lower total upgrade price.
