OCZ Vertex 4 256GB Review



When you look at what the Vertex 4 brings to the table it's hard not to be impressed. Equipped with OCZ's latest Indilinx controller that is optimized to work with data streams of varying compressibility without running into performance bottlenecks, the Vertex 4 delivers excellent performance when running in its wheelhouse. When you look at the results in ATTO, Crystal Disk Mark, AS SSD and IOMeter it is clear to see why the drive feels so fast when working with it. When you look at the average response times on this drive it just reinforces the quickness you feel that is not just a figment of your imagination.

OCZ recently released a firmware upgrade for the drive that is a significant upgrade from the 1.3 and 1.4 firmwares as it helps increase the sequential read performance. This version 1.5 update is available from OCZ's support site and is implemented using the OCZ toolbox for the Vertex 4. When coming from the firmware this is a non destructive update.

In the ATTO testing the Vertex 4 met or exceeded the read and write specifications with the new firmware of 560MB/s read and 510MB/s write. OCZ nailed the performance with this drive as well as the reliability concerns that come with a new controller. To make sure that the end user has piece of mind for the long term usability of the Vertex 4 OCZ has increased the length of the warranty by two years over the warranty period in place on the Vertex 3 to five years.

Available in capacities from 64GB to 512GB the Vertex 4 will set you back between $99 and $699 with the 256GB variant at an appealing price point of $219. I was unsure how this update to the Everest lineup would fare but having worked with the Octane it's easy to see how this update backs off on the raw sequential speed and focuses on everyday workload performance and responsiveness. If you currently have an SSD, then is this enough of an increase for you to switch? It depends on what you want out of a drive, but as a new purchase the Vertex 4 offers up excellent performance for a modest price along with OCZ's support network to get you through any challenges.
