Corsair Performance Series Pro (256GB) Review

AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.

Incompressible sequential read testing is fairly boring as nearly all SSD capable of SATA 6Gb/s perform the same, and the Performance Pro is no exception.

Incompressible sequential write speed is another story, though. Here the Performance Pro is dominating our charts. It's actually surprising how big the difference is. We are looking at over 60MB/s (17.2%) difference between Plextor M3 and the Performance Pro.
