Actually both rotational speed and bearing construction matter

It is true that drive spinning idle noise (usually a high pitched whine) increases when you increase the rotational speed.

It is also true that *often* (not always) seek noises increase when you increase rotational speed.

However, seek noises are more the function of bearing type, decoupling and casing used.

Fluid bearings are usually the most silent types.

IBM does not make a silent drive - none of them is (compared to the competition).

It is also true that newer high speed hard drives can be less noisy than slower speed old drives.

However, new slower speed drives are MUCH more silent still than newer high speed drives.

So the rough equation of high speed = high noise still remains, if you compare drives of similar age (i.e. new 7200 rpm drive vs new 10 000 or 15 000 rpm drive).

If you don't believe me, go to www.storeagereview.com and read the actual acoustic measurements for yourself.

Or do the same as I do: buy a lot of hard drives and learn it the hard way :)

OK, we agree, you can get a new, fast, quiet drive. - Swingline 14:43:54 03/15/02 (1)

Depends on what you call 'quiet' - Halcy 09:42:52 03/19/02 (0)
