Sound editing -- maybe, but I think modern disk are fast enough these
days for these things
Video editing is also debatable IMO -- I think in a lot of cases it's
faster if you read the source from one disk and write the video to
another. If you do things like this on an RAID 0 you get higher transfer
rates, but the hdd-heads of both drivers often need to reposition
between source and target... So the seek times eat your higher transfer
