OCZ RevoDrive 120GB PCI Express SSD

Interface speed has always  been an advertising gimmick in the age of magnetic storage, as hard drives never delivered enough performance to  push the limits of the pipes to which they were attached.   At the time they were released, ATA-133 did not provide any faster   performance than ATA-100, and neither did  SATA 3 Gbps over  SATA 1.5 Gbps.  However, with the rise of the SSD, bandwidth is starting to become an issue.  High performance models are pushing boundaries, particularly when performance junkies combine two or more in RAID configurations.

The OCZ RevoDrive is a high performance storage product that uses the PCI Express bus to go beyond the limits of SATA. As a PCI-E 4x card, it can handle up to 16 Gbps — one PCI-E 2.x lane can push 4 Gbps.  The card/drive uses a pair of SandForce controllers which are used in many popular budget SSDs such as  the  OCZ Vertex 2,  Corsair Force, and G.Skill Phoenix series (all 3 Gbps models).  The secret to SandForce’s success is a fast compression scheme that lowers the amount of data to be written, resulting in a net performance gain.  To boost speeds further and actually make use of the extra bandwidth, the RevoDrive uses a Silicon Image 3124 software RAID controller, allowing the two SSD partitions to work in tandem in RAID 0.
