Multiple disk access commands such as XOR commands are broken down into their constituent read and write parts and, if in LBA sequence, coalesced into pipes. These XOR read and write commands are then provided to the RPO algorithm of the HDD for scheduling along with data reads and writes. The actual XOR buffer operation is also scheduled by the RPO algorithm, advantageously to occur during a seek for another read or write.
