Unless I'm misunderstanding what you're suggesting, that would mean
two or more RAID partitions for the same array on a single drive.
Which means that if one drive fails, you could lose more than one
part, and RAID-5 is NOT guaranteed to recover fully when more than one
part of the array fails.

I've thought about writing a program that would present itself as a
file server (maybe Samba, most likely WebDAV for the first version),
and manage a set of files distributed over multiple hard disks. Kind
of like RAID-5, but running at a filesystem level rather than a block
level. It would give me the flexibility I have in mind, but I'm not
sure whether or not it's already been done (although I know Google has
