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 OCZ Vertex 2 100GB solid-state drive was able to reach 233MBps on the read test and 235MBps on the write test in the I/O Comparison benchmark.
Benchmark Results: The OCZ Vertex 2 100GB solid-state drive was able to reach 280MBps on the read test and 238MBps on the write test in the Overlapped I/O benchmark.
4MB Files Test Comparison Chart – Overlapped I/O: The OCZ Vertex 2 100GB SSD scored very well against the drives in the benchmark.
