SanDisk Extreme II SSD Review

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.

Bring Your Translator:

The compressibility of the data being transferred on the SanDisk Extreme II drive has no measurable impact on performance. In both the Read and Write tests, all three of the SanDisk Extreme II drives we tested offered flat, consistent performance. As we've seen in a few of the other tests, the 240GB and 480GB Extreme II drives put up read and write scores among the best drives here, but the 120GB model can't offer quite the same write performance.
