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.

As you can see, the SandForce-based AData XPG SX900's performance varies significantly (especially in the read test) depending on the compressibility of the data being transferred. None of the other drives are affected much at all, however, and offer consistent performance regardless of data compressibility.
