It predates and is simpler than HP's proposal (which met resistance in T10 and was subsequently dropped). So we revived our original Type 4 proposal which is 16 bytes of protection information per interval (CRC32C, 48-bit LBA and 6 bytes of app tag). The proposal has been sitting around for a while waiting for SBC-4 to open. -- Martin K.
