Iometer (Mixed Workload Performance)

Website: Iometer

Our last bout of Iometer testing looks at mixed workloads. After all, a drive is rarely just reading or writing; in most instances it's doing a bit of both. As such, we look at some basic mixed patterns, first with sequential 128KB data at QD1 and then with random 4KB data at QD4. This is of course still a synthetic test but should tell us a bit more about a controller's strengths and weaknesses. Each test is run for two minutes with the average reported.
