Mirroring offers redundancy but uses twice the disk space, AND is slower than striping.

Actually, disk Reads of a stripe and a mirror are the same. Writes are same speed as a single disk (half the speed of a two disk stripe).

If you use something like gmirror and set the algorithm to 'round robin' reads are done from both disks.... if you access a 2MB file, 1MB is read from disk0 and the other MB from disk1.
