Here we see the statistical differences between the smaller capacity 128GB drive and the 256GB that OCZ sent over for review. OCZ is also definitively pointing out which benchmark programs were used to obtain the claimed performance numbers, although what is not clear is which platform was used in conjunction with the drive, which as we'll see in a bit can make a significant difference.
Opening the Vector up we find a setup similar to the Vertex 4, with a thermal pad between the Indilinx processor and metal frame. By the way, doing so will void that nice five year warranty, so obviously we don't recommend trying this on your own product.
The main processor is OCZ's in-house Barefoot 3 controller, the Indilinx IDX500M00-BC. If you recall, the Vertex 4 used a similarly-stamped IDX400M00-BC, which as Shawn pointed out was actually a Marvell controller with some customized firmware. The Barefoot 3 however is a true Indilinx design and the first to make an appearance in a SSD since OCZ acquired the company two years ago. Caching is provided by two 256MB Micron 2DM77-D9PFJ ICs, one on either side of the board, and sixteen OCZ-branded Micron M2502128T048SX22 16GB 25nm NAND chips. A quick calculation reveals that OCZ has not allocated any of the available 256GB capacity for over-provisioning as common in other SSD designs.
Let's get the Vector SSD installed and see how it performs.
