ATTO Disk Benchmark

ATTO is a more straight-forward type of disk benchmark that measures specific transfer sizes across a specific volume length.  It measures raw transfer rate for both reads and writes and graphs them out in an easily interpreted chart.  We chose 8kb through 1024kb transfer sizes over a total max volume length of 32MB.  This test was performed on blank, formatted drives with NTFS partitions.

Again, our apologies for all the thumbnails but as we've said before, the pictures speak volumes.  A few obvious observations we can easily take away are that all of the MLC-based SSDs had a tougher time with small block writes from 8K - 32K and didn't become competitive with the SLC-based drives or the VelociRaptor, until we hit the 64K transfer size threshold.  At that point, the Core Series OCZ and Super Talent drive held their own, though, in general, they did fall a little short on write performance versus the others. And there's no question, the VelociRaptor 10K RPM hard drive smoked all SSDs in this test, in terms of write performance.  From a read perspective, the MLC-based OCZ and Super Talent drives outpaced even the VelociRaptor in large file transfers but lagged behind it in small 8K - 32K transfers yet again.  Finally, performance with the SLC-based SSDs was significantly flatter and more deterministic versus the MLC-based product.  The SLC drives had fewer spikes and dips exhibited depending on transfer sizes but generally offered less throughput overall versus their MLC siblings.
