Next, we have the average I/O response time (the lower the better of course), starting with 64k streaming reads. While all the drives were fairly similar at queue depth 1, they diverged as the queue depth increased, with the Intel-based drives again doing well. It was not till queue depth 5 before the OCZ and Patriot SSDs got back into the competition.

When it came to the writes however, the OCZ and Patriot SSD drives were significantly slower at the start compared to even the mechanical hard drives, improving only at queue depth 5. The Kingston drive was the best performer, with the Mtron slightly better than the Intel among the SSD drives.

When it came to the file and web server workloads, the SSD were leagues ahead of the WD hard drives, so much so that there was not much differences between the SSDs, with the Mtron a tad behind for the file server workload.
