WD1200 Breaks New Capacity Record With 120 GB At 7200 Rpm

There is hardly any difference between the previously tested 100 GB model WD1000 and the new 120 GB drive. Both hard drives have three platters and a per-platter capacity of 40 GB each. While the 100 GB drive clearly does not make use of its full capacity, WD obviously didn't have to do much more than alter the firmware and maybe run some quality checks in order to activate the remaining 20 GB.
