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.

The OCZ Vertex 4 drives offer very consistent read and write performance, regardless of the compressibility of the data. In the read test, all of the drives are bunched close together. In the write test, however, there is a significant spread. The SandForce-based drives' performance takes a nosedive with incompressible data, whereas the other drives are more consistent. The Vertex 4 drives offer some of the best performance in the write test, sandwiching the Samsung SSD 830.
