For the long-term performance stability test, we set the drive up to run a 20-minute 4K random test with a 30% write, 70% read split, at a Queue Depth of 256 over the entire disk. The 2TB Exceria Pro averaged 121,185 IOPS for the test with a performance stability of an excellent 91%. It did seem, however, that there were some signs of thermal throttling towards the end of the test run.
