This last would be way the best. Remember, with raid-0 you only need ONE failure to trash your partition. And with say four disks, you quadruple your chances of said failure. What size are these disks? And given the price of disks, if you're trying to combine small disks ( <1TB typically) what's the point? It'll probably cost more in electric to run all these disks than to just buy a new large disk and bin the old ones. Cheers, Wol
