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.

Intel X25-M Gen 2 160GB

OCZ Vertex 120GB

The Micron C300 pulled ahead of the competition in both reads and writes in the ATTO benchmark. When the drive was connected to a SATA II interface reads and writes were in the 260MB/s and 215MB/s ranges, respectively. When connected to a SATA III port, however, those numbers jumped up to over 375MB/s for reads and 220MB/s for writes.
