Corsair Performance Pro Series 256 GB Review



Corsair has taken a controller and tweaked the firmware to deliver a drive that offers excellent performance, especially when working with compressed data. Throughout testing, the Performance Pro delivered consistent results and did not show any signs of performance degradation. Many times, drives are tested with no stored data, which shows the best-case scenario for performance. However, that does not represent our day to day usage patterns – these drives see reads and writes of data all day long. Thus, there will undoubtedly be some drop-off unless you let the drive wait for a TRIM cycle for cleanup. This is where the use of the Marvell 9174 controller and its alternative garbage collection routines pays off in spades. The Marvell controller sets up an aggressive routine that runs more often and independent from the operating system at hand. It will maintain performance regardless of whether you run something other than Windows 7 or a RAID array, where TRIM is usually not supported.

Across the board, the Performance Pro 256 GB drive offers excellent performance. It easily reaches its rated speeds of up to 515 MB/s sequential read and 440 MB/s sequential write in the ATTO testing. What is more impressive, are its results in CrystalDiskMark and AS SSD, where the Performance Pro delivered the highest performance of any non-RAID drive I have looked at so far. In the IO Meter testing, the Performance Pro was easily the highest performing drive once again. Corsair and Marvell have put together a drive that just flat-out delivers. Priced competitively at $419, the 256 GB Corsair Performance Pro drive easily makes the short list. It's priced right, delivers awesome performance, is built with high-end performance in mind, and comes with a 3 year warranty. It's not the fastest drive, but has the Cojones where it counts and rightfully earns the "Performance Pro" name.
