Benchmarks: Atto Disk Benchmark

The Atto Disk Benchmark is used to measure read performance of each drive using 1KB, 2KB, 8KB, 32KB and 128KB sample files. As you can see, for the most part the Intel X25-M is the fastest SSD, losing only to the OCZ Vertex 2 Pro and Vertex LE drives once the file size reaches 128KB. The Vertex 2 was slightly slower than the Vertex 2 Pro and Vertex LE drives, while it dominated the original Vertex when working with 2KB, 8KB and 32KB files.

Again we find that the Vertex 2 is slightly slower than the Vertex LE and Vertex 2 Pro drives when measuring write performance. This meant that although the Vertex 2 was slower than the original Vertex and the Intel X25-M when working with 1KB and 2KB files, it was considerably faster than both once the file sizes exceeded 2KB.
