At least one supplier of terabyte arrays mitigates this effect and improves seek times, by using 750GB drives and only utilising the first 500GB.
You can do some tuning using partitions this way, assuming you have data which are small, and/or accessed infrequently, and some other data where transfer rate is important. Same idea, but you get to use all of the drive capacity.
