The specs I read from the manufacturers indicated the newer generation
7200's were no more power hungry than the older 5400's. I didn't look
and see if the newer 5400's (if there were any at the time) were
different than the old 5400's (it wouldn't be surprising if the were
better).

? If the disks have the same density, the 7200 RPM one should read
72/54 times as fast once the reading/writing starts, no?
