OCZ's RevoDrive Preview: An Affordable PCIe SSD
 

OCZ sent us the more expensive $699.99 240GB version but the sort of performance scaling we'll show here today should apply to the smaller, more affordable card as well. The genius isn’t in the product, but in how OCZ made it affordable. OCZ is able to offer a single card at very little premium compared to a standalone drive. A standard OCZ Vertex 2 E 120GB (13% spare area instead of 22%) will set you back $349.99. A 120GB RevoDrive will sell for $369.99 ($389.99 MSRP), but deliver much higher performance thanks to you having two SF-1200 controllers in RAID on the card.
