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 750GB Optane DC P4800X averaged 173,382 IOPS for the test with a performance stability of 98.87%, or 99% if you prefer, which is the stability figure you should expect from a dedicated enterprise drive.
