OCZ Vertex 3.20 120GB SSD
Cosmetically the 3.20 isn't much different from the last known Vertex 3 drives on the market. It uses the same black plastic cover over a metal base tray.
The part number now has an extra .20 at the end. All of the mounting points are located on the metal base tray.
Vertex 3.20 remains a 9.5mm Z-height drive. Before OCZ neutered their product map, they had a 7mm Vertex 3, but those are long gone now. We're a bit surprised OCZ didn't move Vertex 3.20 over to the 7mm form factor and reduce the number of different cases used. The 7mm Vertex 3 appears to use the same case as Vector. Then again, OCZ may have several 9.5mm cases in a warehouse and this drive is a good excuse to get rid of them.
As I was writing this article ADATA announced a 7mm move for their entire product line. We hope OCZ follows suit soon.
The SATA power and data connectors are where they should be.
Just like the 240GB Vertex 3.20, the 120GB model uses sixteen NAND flash chips, eight on each side. The familiar SF-2281 controller keeps everything in line, but we noticed that OCZ didn't use the new B02 stepping that reduces power.
The big change with this product is the new 20nm Intel flash.
