Western Digital VelociRaptor 1TB Hard Drive Review

ATTO & CystalDiskMark Benchmarks

ATTO v2.41

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.

ATTO – Intel Z68 Platform

Benchmark Results: For the most part, the Western Digital VelociRaptor 1TB drive puts up scores roughly equal to the other hard drives and hybid/cached drives. Really, reads and writes in the low 200MB/s range is smoking it for a hard drive and exceeds the rated specifications.

CrystalDiskMark 3.0.1 – Intel Z68 Platform

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

Benchmark Results: Again we see the sequential scores in the low 200 MB/s range and really outscores the other hard drives and cached drives in the bulk of the tests.
