If you quickly showed a computer enthusiast the RevoDrive, they might think you had a sound card or perhaps a drive controller... but they most likely wouldn't assume you were holding a high performance storage device.
The next several images will take a closer look at the 50GB RevoDrive to identify they key components it features. First we see that it is a full height expansion card that uses an x4 PCI Express interface. The brownish PCB is silk screened and the chips are labeled to make identifying the key components rather easy. The images below show that there are eight NAND flash chips on either side, and we'll take a closer look at them in just a bit.
A Silicon Image SiL3124 RAID controller manages the RAID 0 configuration of the two 'virtual' drives found onboard. To the right of the RAID controller we find two SSD controllers, with one labeled "Drive 0" and the other labeled "Drive 1". These are both SandForce SF-1222 controllers, which is one of the more popular SSD controllers in the enthusiast market right now. To the right of the SSD controllers we find the MLC NAND flash chips, with eight on either side for a total of sixteen chips.
The next image takes a closer look at the flash chips, which are all labeled "i 29F32G08AAMDB". These are Intel branded Multi Level Cell NAND chips, each with a capacity of 4GB. With a total available capacity of 50GB, simple math tells us that OCZ Technology has set aside 14GB of reserved space for wear leveling.
