Automatic Acoustic Management
From Wikipedia, the free encyclopedia
Automatic Acoustic Management, or AAM, is a noise management feature available in most modern hard drives. The feature reduces the seek noise produced by hard drives, at the cost of a small decrease in performance. It is software controlled, and is usually initially set to favor performance. AAM level may be changed by the end-user, using a software tool. The same tool works for every hard drive that supports AAM; Hitachi's Tool[1] is often used.
Many Seagate hard drives do not feature AAM, due to a dispute they had. Some people[who?] believe that the PATA 7200.7's had AAM enabled by default, whereas the SATA (non-native) had it disabled, as the SATA drives tended to be a little faster and noisier.
