Maybe I'm missing something, but how is a RAID10 of just two devices is
considered reasonable without any questions or explanation? What is the actual
layout that is expected here, and what benefits (or even differences) does it
have compared to RAID0? I thought you need at least 3 devices (and h/w RAID
controllers might even require 4) for RAID10 to start making sense.
