It is done at a block level now with so many blocks of a file going to the first drive, then the next and so on. Don't need a cluster of computers to do it, just a RAID controller or even software that drives the multiple drives. Linux has a software RAID driver already that does various levels of RAID implmentations, including RAID 0. > It's a thought. It's a good one.
