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.
There are three main things to take away from these AS SSD Compression Benchmark results. First, notice that the performance of the SandForce-based drives tapers off as the data become less compressible. Second, the performance of the SandForce-based drives equipped with Micron NAND show a much sharper drop-off than the drive with Toshiba NAND. And finally that the Marvell controller-based Crucial M4 performs identically regardless of how compressible the data is.
