ATTO Disk Benchmark

ATTO is a more straight-forward type of disk benchmark that measures transfers across a specific volume length.  It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart.  We chose .5kb through 8192kb transfer sizes over a total max volume length of 256MB.  This test was performed on blank, formatted drives with NTFS partitions.

Seagate Momentus XT

WD Scorpio Blue

Seagate Barracuda 7200.11

Patriot Zephyr 128GB


The Seagate Momentus XT performed somewhere in between the WD Scorpio Blue and the Barrcuda 7200.11 in the ATTO Disk Benchmark. The true solid state drive, however, was in a league of its own. But again, we must reiterate, a low-level benchmark like ATTO that simply tests bandwidth with varying block sizes, will not benefit from the adaptive memory technology incorporated into the Momentus XT.
