OCZ Agility 4 (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 performance is nowhere near as bad as it was with Agility 3, but it's significantly behind other drives.

Incompressible sequential write performance is not Vertex 4 level, but still a bit better than average.
