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.
In the AS-SSD read test, the Vertex 450, like all of the other drives, posted extremely consistent scores--except for the Vertex 3.20, which had a rough start due to the 1% compressible data.
The write test results are far more interesting; the Vertex 450 was again consistent and was able to hang tight to the OCZ Vector. SandForce drives, as we’ve mentioned in past reviews, struggle with incompressible data. With its Indilinx controller though, the Vertex 450 offers both top-notch consistency and excellent bandwidth.
