OCZ Vertex 4 128GB SSD

Here we get our first look at the 128GB model. Nothing has changed on the outside from the 512GB and 256GB you read about last month and yesterday.

The model number, serial number and such are on the back of the drive like most OCZ SSDs.

All of the mounting points are located in the under sheet metal. The Vertex 4 line does use a plastic top, though.

The SATA power and data ports are offset to where they should be and the desktop adapter bracket offsets the drive so the ports line up in traditional 3.5" form factor locations.

We expected to find just eight 25nm flash chips inside, but were pleasantly surprised to find eight on each side with a total of sixteen. In the middle you'll see the Indilinx Infused controller and just to the right of the controller is half of the DRAM buffer.

OCZ has been fairly quiet on the buffer sizes in their specifications sheets. The 512GB model has a massive 1GB of DRAM capacity, the 256GB has 512MB of capacity and we expected to find 256MB on our 128GB sample today. We were wrong again; the 128GB Vertex 4 has the same markings on the DRAM as our 256GB drive (2DD22), so it should have 512MB of DRAM too, divided into two 256MB chips.
