Iometer
We have saved the hardest test for last. Iometer is the king of savage benchmarks, and we set it to run for 30 minutes by using a 4K random pattern, with a queue depth of 32 users, that takes in the entire capacity of the drives. Think of the test as pre-conditioning.
Speed is measured with respect to input/output operations per second (Iops), so the higher the better. The first test shows the maximum level achieved, but the second is more telling. It describes what happens when the SSDs fall into a steady-state speed, defined as when the drive is full and has to erase blocks before writing new ones, thus dropping performance.
The TR200 doesn't fare well in this regard, perhaps due to it not having some onboard cache to juggle operations, or not having lots and lots of overprovisioning space, meaning lacklustre write speed rears its head again. However, it does take longer to hit this steady-state speed, and appreciating that this is not a normal workload for an entry-level consumer drive, it is unlikely to become this sluggish in your PC.
