Our vibration and power consumption tests suggest that the differences were
a direct result of the number of platters in each drive. The level of vibration
was better than average on the 2TB LP, good on the 1TB Pipeline HD .2 and almost
non-existent on its 500GB brother. In this regard, they are all considerably better than Seagate's 7200rpm drives. Noise and power draw all scaled with the size of
the drive.
Power consumption during seeking activity was lower than 7200rpm drives, but
idle power was particularly impressive with the 500GB Pipeline HD .2 setting
a new record for 3.5" drives. The 1TB version was not far off.
COMPETITIVE COMPARISON
When it comes to noise related properties, the 500GB Pipeline HD .2 is more
or less comparable to the Samsung 500GB EcoGreen. Both have only a single
platter; the EcoGreen uses less power during seek, but
the Pipeline generates 2~3 dBA less noise in seek.
The 2TB Barracuda LP does not match the 2TB WD Green drive. It is
louder, vibrates slightly more, and uses more power unless you disable the Green
drive's head parking feature.
