Wouldn't multiple platters of the same density still produce a throughput that's a multiple of what it would have been with a single platter? I'm assuming the heads on the multiple platters are all able to operate simultaneously. Anyway, here's a data point: http://www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_7200_12.pdf All the disks from 160G up to 1T have the same sustained data rate, which is 125 MB/s _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
