Drive Surface Temperature
Apparently, the two-platter drive runs a bit cooler than the three platter model, which comes as no surprise.
As expected, idle power is lower on the drives that utilizes less platters. The 450GB and 600GB drives with three platters both require 0.5W more power in active idle (spinning).
Delivering data at peak throughput results in similar power consumption. The difference between two and three platters is smaller now.
Power consumption during delivery of a defined data stream (video) was highest on the 450GB drive for some reason.
Workstation I/O power consumption scales with the amount of heads utilized.
