ATTO Disk Benchmark and CrystalDiskMark

First we run ATTO Disk Benchmark with all transfer sizes selected and queue depth set at 4. Many SSD manufacturers, especially those selling SandForce based SSDs, use ATTO results to determine max speeds that consumers see on final packaging and specs sheets. ATTO uses compressible data during benchmark. CrystalDiskMark is another popular storage benchmarking tool. It allows to switch between compressible and incompressible data. We run benchmarks in both modes to see how SSDs deal with different types of data.
