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 AS-SSD compression benchmark shows a significant difference between the performance profiles of the SandForce-based drives and the Marvell-based Crucial M4. SandForce controllers perform best when paired to synchronous flash memory and moving highly-compressible data. The Marvell-based drives, however, offer consistent performance regardless of the data compressibility of the data. With its latest firmware update, the Crucial M4 offers excellent consistent read performance, but middle-of-the-road writes versus the SandForce drives.
