Samsung has long been known for producing quality
affordable monitors for many years but not for its production of
hard drives. Today we are looking at the SpinPoint SP4004H which is
a 7200 RPM, ata100, 40 gig hard drive. Samsung has
incorporated Acoustic Management through the use of their NoiseGuard™Acoustic
Noise Suppression Technology and their SilentSeek™ Technology to
bring their 7200 RPM hard drives down to 5400 RPM noise levels.
 
Since most of the noise is generated from
the motor and the sensor, Samsung has targeted these two areas to work
on, when implementing its NoiseGuard™ technology. Here's a
picture of what they use to calculate noise:

This information in regards to noise levels helped Samsung to move ahead
and include Noiseguard. What it really is, is replacement of
material that makes up the hard drive. Different materials were
used until the best noise absorbing was found. This included the
motor and also the hard drive cover. Find out more about it at the
Samsung
Website.
