OCZ Agility 4 256GB Solid State Drive Review

Agility 4 Overview
The Agility 4 solid state drive looks much like any other 2.5-inch solid state drive from OCZ.  On the front there is a sticker that lets you know it is the Agility 4 drive and that it is Indilinx infused.

On the back of the drive there is another sticker with all of the part numbers and serial numbers for the drive.  Also you will notice a large “void if removed” sticker over one of the screws.  There are 4 mounting holes on the bottom of the drive.  There are also 4 mounting holes on each side of the drive.

Just like all SATA drives you have both SATA power and SATA data connections on the drive.

Getting inside the drive is very easy, you just remove the 4 small screws and take the back off the drive.  Keep in mind by doing this you are voiding your warranty.  Once removed you can see that OCZ uses a thermal sticker to keep the Everest 2 controller nice and cool.  Taking a closer look at the PCB we can see the Indilinx Everest 2 controller in the center with eight OCZ labeled NAND chips surrounding it.  There is also a 256MB Hynix cache chip present.

You can actually take the entire PCB out of the casing by removing 4 more screws.  Once out we can flip it over the reveal eight more OCZ labeled NAND chips and another Hynix 256MB cache chip.  This gives you a total of 16 NAND chips and 2 cache chips.  The 16 NAND chips are 16GB each and are asynchronous NAND.  Both Hynix cache chips give you a total of 512MB of cache unlike the Vertex 4, which had 1GB.
