CrystalDiskMark Benchmark Results

Website: CrystalDiskMark

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

CrystalDiskMark 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.
