The Mercury Accelsior is the first ever PCI Express drive from OWC, maker of the SSD products Mercury Extreme Pro and Electra. It is a plug 
and play drive which means it does not require any driver when installed in both Windows and Macintosh computers. The Mercury Accelsior is rated at 780 MB/s for sequential read and 648 MB/s for sequential write. Peak IOPS is at around 100,000.
The SF-2281 powered solid state drive is constructed using a pair of 24nm Toggle NAND each with their own controller. When a storage upgrade is needed, the user only needs to detach the “blades” from the main PCB unit. It is cheaper to do such than by a whole new unit. The Mercury Accelsior comes in 120 GB, 240 GB, 480 GB and 960 GB capacities.

Reviews:
The OWC Mercury Accelsior PCIe SSD RAID 0 offers some serious advantages, despite the high price compared to a conventional hard disk. One should carefully weigh, these days, the low cost of an HDD in light of its so-so performance, spin-up lag and customary headaches.
Features aside, one thing that we always gauge products on is performance. So how did the Mercury Accelsior perform? It definitely performs much faster than all of the solid state drives we have reviewed this year because it is not held back by the SATA III bottleneck. In ATTO we saw scores of 809MB/s read and 801MB/s write! That is very impressive and the Accelsior is one of the fastest drives of all time that we have tested.
