Crystal Disk Mark Benchmark Results

Website: Crystal Disk Mark

We've chosen to drop ATTO Disk benchmark from our SSD reviews in place of Crystal Disk Mark. ATTO's highly compressible data pattern gave an unrealistic view of drive performance, and including a 'best case' benchmark for the benefit of SandForce drives was becoming less relevant as SSD partners move away from the SandForce platform.

Crystal Disk Benchmark is similar to AS-SSD in its use of incompressible data files, performing sequential, 512KB and 4KB random read and write tests. it also tests with a more realistic 32-queue-depth as opposed to AS-SSD's 64-queue depth, a load that's less relevant for a home-user.
