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.
