Iometer (Sequential Performance)

Website: www.iometer.org

Our one hour consistency test acts as something of a preconditioning for the drives, although before doing any further testing we trigger the TRIM command by performing a quick format in Windows and leaving the system idle for five minutes. This gives the drive a fair chance to recover some performance. We then perform sequential read and write tests with Iometer using 128KB throughput. We test first at QD1 and then at QD4 to simulate light and heavy desktop workloads (even power users rarely exceed QD4 at home). Each test is run for a full minute to eliminate initial burst phases, and in each case it's the average speed we're reporting.
