Alguns discos rígidos são mais silenciosos que outros. Revisão silenciosa do PC cobre isto completamente completamente :
Until about two or three years ago, the majority of hard drives on the market used ball-bearing motors, which had a characteristic high pitched whine and other objectionable airborne noise. Since then, the industry has shifted to much quieter FDB (Fluid Dynamic Bearing) motors, with the result that most recent drives are significantly quieter than older drives ... All major drive manufacturers now use FDB motors in their current lineups. If you have a typical non-FDB drive that's more than a year or two old, the simplest way to achieve lower noise (and improved performance) is to swap it for a new drive, almost any new drive.
There are three other factors that affect drive noise:
- The number of platters in the drive
- The difference between idle and seek
- Automatic Acoustic Management (AAM)
