OCZ Agility 4 (256GB) Reviewby Kristian Vättö on September 1, 2012 1:00 PM EST
The Agility 4
Besides the sticker, Vertex 4 and Agility 4 are virtually identical.
The PCB is actually screwed to the top part of the chassis, which is not very common. The top part of the chassis is made out of plastic, whereas the bottom part is metal. There's also a single thermal pad for the controller.
The controller is the same Indilinx IDX400MOO-BC (also known as Everest 2) as is found inside the Vertex 4. The silicon is provided by Marvell, although neither OCZ or Marvell has confirmed which exact silicon the Everest 2 is based on.
Similar to the Agility 3, the Agility 4 uses Micron's asynchronous NAND. As far as I can tell, Micron was the sole supplier of NAND for the Agility 3, so I would expect this trend to continue. There are eight NAND packages on each side of the PCB, bringing the total NAND package count to sixteen. Since our model is a 256GB version, each NAND package is 16GB (two 8GB dies).
There are also two Hynix 256MB DDR-1333 chips. All our Vertex 4 samples have had Micron DRAM in them, though it's very likely that OCZ is using multiple suppliers.
