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.

Benchmark Results: As you’d expect, the SSD and hybrid drives far outpace the spinner but surprisingly, the 7200 RPM Momentus kept pace, and for the most part bested, the aging 10,000 RPM VelociRaptor.

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: On the CrystalDiskMark test, the VelociRaptor did fare than the Momentus but with one exception, the margin wasn’t significant which just shows how far the spinning platter technologies have come in just a few years.
