The Atto Disk Benchmark is great for analyzing how file sizes affect performance, and we have used 4KB, 8KB, 16KB, 32KB, 64KB and 128KB transfer sizes. First up we have the read performance, and based on what we have seen already we know that this is where the SSD drives do quite well, even with smaller files.
The Intel X25-M 80GB delivered the best results here, and although its top end performance was not as good as the OCZ Vertex 120GB, it was considerably better at handling 16KB and smaller files. The OCZ Vertex 120GB was faster than the Super Talent UltraDrive ME 64GB, despite the fact that both drives are based on very similar hardware.
This is where things start to get more interesting, as we look at the write performance. The G.Skill Titan 128GB suffered a bit when writing smaller files, but it did away with some pretty impressive results when working with 32KB or larger files.
The Intel X25-M 80GB was surprisingly unimpressive in this test, with a maximum throughput of just 80MB/s, though that matches Intel specifications. The OCZ Vertex and the Super Talent UltraDrive were superior to the Intel X25-M 80GB regardless of file size in this test.
