Instead of writing a single stream of files to just one disk until full, then going to the 2nd disk, then 3rd, etc. Why not write full files to all disks at the same time? That means file writes are always at single disk speed, but it means files can be written in parallel. For sequential writes it would be almost as fast as raid0 but without the ensuing data loss.
