Arguably we may prefer a mapping that gives us 512 bytes/LBA while informing plug 'n play that read/write of larger aligned quantities may complete significantly (like 100X) faster. Already t10.org PDT x05 on paper says bytes/LBA is fixed at 2 KiB, except for non-default modes, yes? So now likewise t10.org, moving in the direction of modeling reality more accurately, might say this for PDT x00. Pat LaVarre
