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.

The SandForce based drives continued their dominant performance in the ATTO Disk Benchmark. All of the drives begun hitting their peak performance once block sized hit the 32K mark, but it was the SandForce based drives that broke out to a commanding lead, especially in terms of write performance.
The 120GB drives perform exactly as their 100GB counterparts do here.
