PCIe SSDs, which combine a RAID chip with several SSD controllers and plenty of NAND flash onto one convenient and speedy package, are not a new idea. We’ve reviewed several, most recently the OCZ RevoDrive3 X2 in December 2011. They can be handy for people who want the speed of modern SSDs but don’t have free 6Gb/s SATA ports (this means you, X58). OWC’s Mercury Accelsior comes in sizes up to 960GB; we tested the 480GB version.
The Accelsior’s blades can be replaced with higher-capacity ones in the future, but will anyone actually do that?
