SiSoft SANDRA Read & Write
Testing began with SiSoftware's SANDRA XII, the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison drives. The benchmarks were run without formatting and read performance metrics are detailed below. We also included SANDRA's graph so you are able to see how the drive performs over time along with the average rated result.
With regard to Read performance, the WD VelociRaptor 600GB is up to 30% faster than the older 300GB version and about 16% to 18% faster than the high-performance, high-capacity reference drives tested here.
The same holds true in SANDRA's Write performance test. Here, the WD VelociRaptor 600GB is about 25% faster than the competition.
