Power Consumption

The M9T's energy efficiency is about average for a 2.5 inch drive, using 0.92W when idle and 2.22W during seeks (random read), but the difference is negligible considering the extra capacity.

The SSHD 2TB's power consumption was excellent for a 7200 RPM model. It used just 4.5W at idle which is about the same as most 5400/5900 RPM drives. Seeking brought that figure up to 7.1W, but this is still lower than the other 7200 RPM drives compared. The two platter design really helps in this regard.

Acoustics

The noise levels of the two drives are similar with the SSHD 2TB measuring about 1 dB higher, but given their respective form factors and motor speeds, they have a slightly different sound. Both are reasonably quiet and innocuous at idle with a gentle "whoosh" being emanated, but the SSHD emits additional high frequency noise, making it sound more hollow. The M9T's seeks are rather soft, so muted that they barely distinguishable. The SSHD's seeks arequiet as well but have a slightly harsher twang that is more pronounced.

The M9T 2TB generates the same noise levels as the Scorpio Blue 1TB; It's a reasonably quiet drive for a 2.5 inch model, but can't compete with ultra-quiet models like the WD Red. What really stands out is the level of vibration it produces, that is, hardly any. It scores 9 on our subjective scale, which puts it ahead of every modern notebook drive we've examined.

The SSHD 2TB is a louder drive, but that's to be expected for a 3.5 inch variant. The noise levels we measured were equal to that of the Barracuda 3TB, so the two get to share the title of quietest desktop 7200 RPM drive. What we didn't expect is the characteristic clicking sound of the head parking after about 20 seconds in inactivity. This is highly unusual for a 7200 RPM desktop drive, though we noticed a similar power saving feature in the Barracuda.

Unfortunately it generates a significant amount of vibration, scoring an average of 6 on our subjective scale. We had four samples in total, two of which scored 6, while the remaining two scored a 5 and 7, so there was some sample variation. In recent memory, only the Seagate Enterprise Class 6TB drive has produced a significantly worse result. We used the SSHD in our recent Quiet ATX Gaming Build and the vibration-induced noise it made prompted us to suspend the drive with elastic cord in a 5.25 inch bay.
