That doesn't agree with my understanding. My understanding, for a single disk, you're right. No disk can come near the bus speed for either SATA or SAS. But SCSI vs ATA, the SCSI is supposed to have a more efficient bus utilization when many disks are all doing thing simultaneously, such as they might in a big old RAID, 48 disks, etc, like you have. 'Course none of that matters if you're serving it all over a 1Gb ether. ;-) I don't know under what circumstances SAS performance would be SATA. Nor do I know by how much. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
