ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds 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 and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

With transfer sizes between 4K and 256K, the Samsung SSD 830 Series drive offered the best Read throughput of the bunch, and remained competitive with all of the other drives as transfer sizes increased all the way up to 8MB. The Samsung SSD 830 Series drive's write performance was very good, but it ultimately falls short of the mark set by the SandForce-based drives.
