Web28 Oct 2024 · "Parity" means that the b th block of disc 2 is the xor of the b th blocks of discs 0 and 1. The point is that, if any single disc fails, we can recover its data because the b th block of any disc is the xor of the b th block on the other two discs. For this to work, it's crucial that the parity data is on a separate discs.
