WD Black 2 Dual-Drive SSD+HDD Hybrid 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.
The WD Black 2's SSD performance is not affected by the compressibility of the data being transferred to and from the drive. Performance is flat and consistent across the board here. Though, as expected, transfer rates are lower than the other drives once again.
