Iometer
We reckon the Iometer test is the gold standard by which consumer drives are judged. The drives are bombarded with large-file-size sequential throughput and small-file random reads and writes. By doing this we can expose any weakness in the controller and NAND setup. The drives go through an hour of preconditioning before running the benchmarks.
It's relatively easy to hit high read IOPS but it's the writing speed that separates the better drives from the rest. A consistent 36K IOPS after a 20-minute run bodes well for long-term running.
