After careful consideration and much regret I have decided to transfer all hardware review activities to a new domain. I purchased Hardwareasylum.com in 2012 and have been working hard to build a new and improved Ninjalane on that domain. If you are reading this you have reached one of the archived articles, news, projects and reviews that were left behind during the site migration.
Please update your bookmarks and be sure to visit the new and improved Ninjalane at Hardwareasylum.com
OCZ 50GB RevoDrive PCI-Express SSD Review
Author: Jim Manis
The product we have in the labs today is the REVO 50GB bootable PCI-E drive. Using RAID 0 SSD drives with Sandforce controllers and their own Silicon image Raid chip sounds like a dream come true for performance enthusiasts. OCZ rates the Revo 50GB drive at 540 MB/s Read and 450 MB/s write speeds with a 4k Random Write of 70k IOPS.
Revo Drives feature MLC (Multi Level Cell) NAND technology and Sand Force 1222 controller which is already a proven combination. The card operates on the PCI-E generation 1 standard for better motherboard compatibility. Bandwidth in this case will not be a limiting factor as the PCI-E bus has more than enough available.
By utilizing the PCI-E lanes the Revo family of drives eliminates the bottlenecks you would encounter with traditional SATA 3GBs or 6GBs interfaces. The card installs into a x4 slot but should work in any lane above x4 size. The speed afforded by a PCI-E x4 is more than enough for a super fast storage device like the Revo Drive 50GB.
In the following pages we will take you on a tour of the drive and subject it to our test suite and see if it lives up to it's specifications, the hype and our expectations.
