-- Samsung SpinPoint P40 SP8004H 80GB Hard Drive
-- Price: ~$89 USD
-- 05.24.2002

   A few months ago we reviewed the Samsung SP40004H and was impressed with its performance.  So when Samsung asked us if we wanted to review their new 80GB hard drive we couldn't refuse.

  In the P40 line of hard drives 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.

Key Features:

  •  3.5-inch High Performance Hard Drives.

  •  80.0GB Formatted Capacity

  •  High Speed Digital Signal Processor(DSP)Based Architecture

  •  Ultra DMA 100 Support

  •  7,200 rpm Spindle Speed

  •  8.9 ms Average Seek Time.

  •  7 way interleave OTF Error Correction

  •  S.M.A.R.T. Compliant

  •  ImpacGuard™

  •  NoiseGuard™
