I guess you do get the performance somewhat in line with the rpm, but even
though I have amassed copious amounts of data due to my obsessive compulsive
habit of keeping all revisions of all code, models, images, renderings, and
documents, the amount of data I access on a daily basis is relatively small
and I'm not concerned with waiting a few extra seconds or minutes per day
for saving/loading. Plus the price difference between 5400 and 7200 drives
add up quickly for 4x 2TB ones.

The real time killer in the bad old days was disk trashing due to
insufficient RAM, which made disk speeds more relevant. Now RAM is more than
adequate, but OS's and applications are more bloated, so a fast system disk
(hence the SSD) is still a good idea, but I don't think the data disks need
to be lightning fast.
