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 SSD Compression Benchmark
Bring Your Translator:

Read performance was similar for all of the drives in the AS-SSD compression benchmark. Write performance, however, differs quite a bit. The OCZ Octane, Crucial, and Samsung drives show flat write performance, which is to say performance doesn't differ much with incompressible or highly compressible data. The SandForce-based drives take a performance hit when writing incompressible data. Note that the Intel drive was somewhat faster than the OCZ Vertex 3 across the board.
