Low vibration is not a strong suit of the DiamondMax 10. Our first sample of the drive had the most vibration of any drive in the lab by a large margin. In fact, we requested a second sample to confirm that the problem was not simply a result of sample variance. The second sample did indeed soften our initial verdict, improving our vibration evaluation by a single grade. Even the second sample still had more vibration than any other drive in the lab, although the difference was not as marked as in the first sample.
