OCZ has retained the same SSD casing design on the Vertex 4 series that we saw on some older models. It has a plastic top with branding sticker and the base, extending to the sides, is a brushed metal. On the base the SATA3 power and data connectors are visible as are the four holes used for installation in a case or laptop.

The most notable difference between this and older models is that it features a connector at both ends. One for standard SATA 3.0 connections and the other for mini-PCIe which will please system builders.

Ndurance 2.0 is designed with enterprise class endurance even when consumer NAND chips are used and features multi-level Error Code Correction (ECC) and Redundant NAND Array (RNA) capabilities along with adaptive NAND flash management. It is also designed to reduce write amplification without the performance hit which is associated with data compression. (Write amplification is reduced without compression by keeping multiple write requests within the host, reducing wasteful copy back operations on unaffected sectors and preserving the NAND cells in the process) Master Thesis On Knowledge Management

The 256GB version sits at 535/380MB/s and for IOPS performance (which we have verified) the 512GB model tops out at 120,000 with 90,000 Random 4KB Reads and Random Writes up to 85,000.

Returning to the features for a moment the drive supports AES-256 encryption and the inclusion of Ndurance 2.0 means this high IOPS performance can be enjoyed for a significant period of time with OCZ leading the industry by using a 5-year warranty on Vertex 4.
