The 1.92TB DC1000M is officially rated as up to 205,000 IOPS for random writes which, after testing the drive with our 4-threaded tests seems to be a very conservative figure as the drive produced a peak of 435,015 IOPS at a queue depth of 128. Apart from QD1 (153,371 IOPS), the drive bettered the official maximum IOPS rating through every tested QD.
