Creating an SSD Over-Provisioning Test
During an SSD over-provisioning test, SSD Profiling Tool first fills the SSDs with random data. It then tests the random write performance of the SSDs over several test phases, each using a different amount of over-provisioning.
For example, if a test is created with a test range of 0-20% and a test interval of 5%, SSD Profiling Tool will test SSD write performance in 5 phases, with over-provisioning set to 0%, 5%, 10%, 15%, and 20%. If the random write performance of the disk is very low during any phase, SSD Profiling Tool will end the phase early and move to the next one.
SSD Profiling Tool creates and starts running the test. The test appears as a background task in QTS.
