It isn't "that" bad. Some simple math. at 5400RPM, the average rotational latency is about 5.5ms, while at 7200RPM, the average rotational latency is about 4.1ms. That isn't a significant difference. Average seek times (mechanical head movement) will probably be similar for the two drives. Even going to 10K rpm only drops the rotational latency down to about 3ms average. I don't personally like _any_ IDE-type drives, as they tend to crush system performance when the drives are really busy. I'd rather have SCSI any time. But that wasn't really the topic here...
