October 23, 20169 yr Would adding a second parity effect write speeds to the array as being written to 2 parity drive as it does with raid 6?
October 23, 20169 yr Can't say I've noticed..... parity checks are a little slower, but not by much at all...
October 23, 20169 yr Author Can't say I've noticed..... parity checks are a little slower, but not by much at all... Ah ok cool. Do you know if each parity set is calculated separately?
October 24, 20169 yr Do you know if each parity set is calculated separately? P (Parity1) is calculated like this: P = d1 + d2 + ... + dn Q (Parity2) is calculated like this: Q = d12 + d22 + ... + dn2 So Q is not merely a backup copy of P, in case that's what you were thinking. R (Parity 3) could be implemented using cubes.
