It doesn't. It solves the "make one big filesystem from a bunch of drives" problem, without losing everything when one drive goes bad.

unRAID is similar, except they add a parity drive in parallel with the data drives, permitting loss of a single drive with no data loss. And loss of subsequent drives without losing everything.

Yeah, pity unRAID wants to be standalone (or in a VM).
