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 Sabrent Rocket 4 Plus averaged 115,934 IOPS for the test with a performance stability of 75.5% which is excellent for a consumer drive. Incediently those figures are a good deal better than the 83,504 IOPS average and 55% performance stability of the 1TB Rocket 4 Plus.
