Agility 3 Overview
The Agility 3 looks like pretty much every other 2.5-inch solid state drive that we have looked at before. On the front of the sticker with the Agility 3 logo and the OCZ logo. The casing itself is made out of aluminum.
Flipping the drive over there is another sticker on the back with all of the serial numvers and other information on the drive. Just like any other drive you have SATA and data connections on the end of the drive. That is it, there really is not much to do this drive at all.
So let’s take a look at what is powering this drive. To get inside all you need to do is remove 4 small screws on the back of the drive and slide the casing off. One it is removed you can check out what powers the Agility 3. As I said the SandForce SF-2281 controller powers the Agility 3, more specifically the SF-2281VB1-SDC chip. This chip is rated a 500MB/s for both read and write. Of course this drive is rated for 525MB/s read and 500MB/s write so OCZ has most likely tweaked the firmware.
Looking at the memory chips there are 8 on the front of the board. These chips are the Micron 29F128G08CFAAA 25nm NAND chips and are 16GB a piece. If we remove 4 more screws we can take the PCB out and see that there are 8 more NAND chips on the back. This give you a total capacity of 256GB, which 240GB is usable. The extra space that is left over is for over provisioning.
