To test how SSDs handle intensive and mixed workloads, we use Iometer to simulate the workloads of four real-world heavy use scenarios: database, file server, workstation and web server. The workloads are similar in that they all use fully random data at a total queue depth of 64, but differ by the sizes of the files used and the percentage split of read/write operations.

Each workload is ran and recorded for five minutes, one after the other, with thirty seconds of data before this going unrecorded so as to discard any initial speed bursts. Five minutes may not seem like much, but as you'll see it's easily enough to separate strong controllers from weaker ones with workloads this demanding. The results here are applicable only to the most demanding users - the average home user or gamer need not concern themselves.
