ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: The Kingston SNM125-S2/80GB SSD was able to reach ~259MBps on the read test and ~84MBps on the write tests.
Benchmark Results: The I/O comparison benchmark showed slightly slower read speeds as the Kingston SNM125-S2/80GB SSD was able to reach ~239MBps on the read test and ~84MBps on the write tests.
4MB Files Test Comparison Chart – Overlapped I/O: The WD Scorpio Black 320GB hard drive did well in ATTO, but got beat by the OCZ Vertex 120GB SSD.
