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 rates here. -- Thorsten Leemhuis <fedora@xxxxxxxxxxxxx>
