Performance?
Authored by: GORDYmac on Oct 18, '04 02:08:44PM

What kind of performace hit does this measure take? If all drives can be quiter, I'd imagine that the feature would be standard [right?] unless enabling it degraded performance.

Performance?
Authored by: allanmarcus on Oct 18, '04 02:22:03PM

A Samsung paper hints that it might be 3%-5%.

The best research I can come up with is this from a Fujitsu paper <http://www.fsc-america.com/pf_silent_drives_e.pdf>:

Activating Automatic Acoustic Management:

The Automatic Acoustic Management feature is activated and configured in the BIOS setup menu of the individual drive. The following options are available for selection in the CD Silent Mode field:

Disabled: The BIOS leaves the settings to the drive itself or to a software tool.
Maximum: The drive can rotate at maximum speed (maximum noise generation)
Medium: The drive can rotate at no higher than medium speed (medium noise generation)
Minimum: The drive can rotate at minimum speed only (minimum noise generation)

Note: The slower the drive rotates, the lower is its performance. Owing to the high read error rate at high read speeds, the relationship cannot be regarded as linear.

I read sth about a hit of the sixth part, more or less.
You can still try some value *between* hex 80..FE as a tradeoff, one maxtor here for example, has a factory setting of hex C0 (ie. kind of the middle between 80 and FE).
