ATTO Disk Benchmark Tests

ATTO is a more straight-forward type of disk benchmark that measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes over a total max volume length of 256MB. This test was performed on blank, formatted drives with NTFS partitions.

ATTO Disk Benchmark
Version 2.46

Samsung 470 Series 256GB

Corsair Nova Series V128 128GB

Intel X25-M Gen2 80GB

OCZ Vertex 2 100GB

The higher rated OCZ Vertex 2 (up to 285MB/s read and up to 275MB/s write speeds) showed the strongest performance in most block sizes, with Samsung's 470 drive trailing not too far behind. What we found most interesting here, however, is that the Samsung drive at times performed better than its rated spec. From 128KB up to 8192KB, Samsung turned in higher read  and write speeds than it's rated for, up to 15MB/s and 2MB/s, respectively.
