I'm trying to find info on how Raid 5 works *in the case of 3 data
drives + 1 parity*. I understand how exor'ing 2 data would yield a
parity bit, but the 3data/1parity algorithm eludes me. I can't think
of how you'd have enough info to recover, even if there were such
a thing as a 3-input Exor. <g>
Is this simple? Or is there a website or paper covering it?
