Acoustics & Power Consumption



Noise levels of the he Deskstar 7K3000 2TB, idle and seeking.

While the Deskstar 7K3000 2TB performs like a beast, the noise level was nothing to write home about, measuring 17 dBA@1m when idle and 18 dBA@1m when seeking. Its acoustic profile has a bit of an electrical twang to it that is perhaps a result of the vibration level of the drive (we measure/record with the drive on a bed of foam but it doesn't eliminate vibration completely); It produced a noticeable 120 KHz spike caused by the drive's 7200 RPM motor. Seek noise was much better, so muted the difference was almost inaudible at one meter's distance.

The last 7200 RPM Deskstar we reviewed, the 7K1000.C, had a significant vibration problem and the 7K3000 is similar, scoring a five on our subjective scale. They are noticeably worse than most drives released in the last four years or so; Unlike other manufacturers, Hitachi seems to have done little over the years to reinforce the casings of their hard disks, still relying on a mostly unchanged industrial design.

Given the drive's level of performance we were surprised to discover its power consumption was quite modest: 5.3W idle and 7.8W when seeking. It's not quite "green" drive territory, but noticeably lower than other 7200 RPM models. Unlike the Barracuda 3TB, it doesn't have any extra power saving features (head-parking) though.

Of all the high capacity 7200 RPM drives we've tested the 7K3000 is actually the most frugal when it comes to power; Only reduced-RPM drives can compete with it in this department. As far as noise is concerned, it's not too bad, marginally louder than the Barracuda 3TB; It's unlikely one could hear the difference, at least if the drives were both suspended. Extra noise from vibration can't be calculated as its effect varies depending on the case.
