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.
