Web-Server, File-Server Patterns
The drives are tested under loads typical of servers. The names of the patterns are self-explanatory. The results are presented as performance ratings which are calculated as the average speed of the drive at every load.
These graphs show us the longest request queue the drives support. It is the point where their performance stops to grow up linearly. Most of the SSDs have this point at a queue depth of 8 requests whereas the Vertex 2, at 16 requests. The latter’s graph has a bend that indicates a firmware flaw, yet this SSD is unrivalled, anyway.
The overall standings agree with the results of the previous tests. The drives that had a good read speed in IOMeter: Database cope with this test successfully, too. We can only note that the Onyx takes last place, being much slower than the other small-capacity products, and the Colossus has a low performance rating due to its small performance growth at long request queue depths.
The Vertex 2 enjoys an overwhelming advantage when there appear write requests. As opposed to the others, its performance grows up at longer request queue depths rather than remains the same, as that of most Indilinx-based models, or lowers as that of the Onyx and Vertex Turbo. The latter two are still faster than the Solid 2, though.
