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 Corsair P256 SSD hard drive was able to reach 210MBps on the read test and 194MBps on the write tests. This drive really burns up this benchmark and makes short work of it.
4MB Files Test Comparison Chart: The Corsair P256 SSD nearly doubles the read and write performance of the Seagate 7200.3 320GB hard drive in the ATTO benchmark. The Corsair P256 SSD is the real deal as you have been able to find out from looking at the five benchmarks the drive was tested with.
