OCZ Vertex 4
Here we get our first look at the Vertex 4. We've seen this case from OCZ a few times before and it does the job. The top cover is hard plastic and the top sticker shows that it is an Indilinx Infused Vertex 4.
The back and sides where the screw mounts are located are made of metal, either aluminum or an alloy. On the back of the drive is where you'll find the model number and with it the capacity size. The serial number is also located here.
All of the mounting points are where they should be and as we pointed out earlier, the screw mounts area all metal.
The SATA power and data connections are offset to where they should be and the included desktop adapter bracket offsets the drive to the standard SATA location of a 3.5" form factor drive.
Our first image from the inner working is actually the bottom facing side of the drive. There is a thick thermal transfer pad for the Indilinx Everest 2 IDX400M00-BC controller that helps dissipate heat into the metal portion of the case. The controller is right in the middle of the drive, most likely situated this way to decrease latency which improves IOPS. Eight Intel 25nm flash chips are located on each side of the SSD. Also on each side is a Micron 256MB DDR3 cache chip.
On the inside, both the 512GB and 256GB models look the same other than the inscription on the flash and the small switching chips shown here on the 512GB drive. The 256GB drive does not have these chips, but both drives share the same PCB design.
