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.

Whether connected to a SATA 3G or SATA 6G controller, the  Barracuda XT was the best overall performer according to the ATTO benchmark. All of the drives are tightly grouped, but the XT was a few MB/s faster then the rest of the pack overall.
