Lately, we have been looking at a slew of Solid-States drives that delivers comparable performance across the board, with most differences coming down to capacity and the NAND flash memory used. In general, the Sandforce SF-2281 controller has been the star of the show, capable of read speeds up and over 550 MB/s. Moving in a different direction from the norm, Corsair has stepped up to the plate with its Performance Pro Series drives, which use the Marvell 9174 series controller and Supercharged Synchronous NAND chips. The Performance Pro Series drives come in two capacities; 128 GB and 256 GB. We will be looking at the 256 GB variant today. The drive has top-line specifications of up to 515 MB/s sequential read, 440 MB/s sequential write, and 65K IOPS 4K aligned. Pricing is competitive, starting at $199 for the 128 GB version and $419 for the 256 GB version. Using a refined controller that bucks the current trend, this drive looks to be an interesting choice. Let’s see if the work on the firmware and hardware pays off.
