AS-SSD Compression Test
Next up we ran the Compression Benchmark built-into AS SSD, an SSD specific benchmark being developed by Alex Intelligent Software. This test is interesting because it uses a mix of compressible and incompressible data and outputs both Read and Write throughput of the drive. We only graphed a small fraction of the data (1% compressible, 50% compressible, and 100% compressible), but the trend is representative of the benchmark’s complete results.
Like all SandForce-based solid state drives, performance will vary with the compressibility of the data being transferred to and from the drive due to the controller's architecture. In the read test, all of the drives are bunched very close together. In the write test, however, the SandForce-based drives trail when incompressible data is used. As the compressibility of the data increases though, so too does performance, and they finish at the top of the charts.
