Our enthusiasm for the WD 750 GB Green Power reviewed in December 2007 prompted us to go hunting for the
1 TB flagship model so we could do more than speculate about its greatness.
With Western Digital's odd IntelliPower system for rating spindle speed, we
wanted to confirm for ourselves that it shared all the characteristics of its
smaller brother — noise, power and all.
The terabyte HDD sample that arrived was promising — with the exception of the model
number on the label, the two drives were identical to the naked eye, with no
indication that anything important had changed. Mechanically, the only difference
should be the addition of an extra platter to accommodate the extra capacity. A quick frequency analysis test confirmed that terabyte model spins at 5,400
RPM just like the 750 GB version. Please see our WD 750 GB Green Power review for all the details.
