ATTO Disk Benchmark v2.41

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.
