OCZ RevoDrive Overview
If you are familiar with the original RevoDrive you know that the RevoDrive is designed as a PCI-Express card that plugs in to one of your open PCI-E x4 lanes on your motherboard. Unlike the original RevoDrive the X2 drive uses 2 boards, which are connected together. Although the overall design is pretty much the same except for a few changes that really help the RevoDrive X2 achieve the best performance possible.
The RevoDrive X2 is actually made up of 4 drives (compared to the 2 on the original RevoDrive) all with their own SandForce SF-1222 controller chip. The big chip in the center of the drive is a Silicon Image 3124 PCI-X RAID controller. This chip will set up 4 SATA II channels one for each of the 4 drives and configure them in RAID-0. This of course will increase the performance. To bridge the connections OCZ uses a Pericom PI7C9X130 bride chip.
Since there are 4 separate drives OCZ uses 2 PCB’s on the RevoDrive X2, this obviously allows for higher capacities. The RevoDrive X2 is available in capacities up to 960GB. Each separate drive is 32GB so in total you have 128GB. This is a 100GB drive so the extra 28GB is used for real-time data compression. OCZ uses Intel 4GB NAND chips.
