My new hard-drive (Seagate ST1500DL003) is a 4KB sector drive that unfortunately reports a "physical sector size" of 512 byte. cat /sys/block/sda/queue/physical_block_size 512 cat /sys/block/sda/queue/logical_block_size 512 cat /sys/block/sda/queue/minimum_io_size 512 I have created my filesystems on it with "mkfs.xfs -s size=4096". Would there be any (performance) benefit if minimum_io_size could be adjusted to 4096 (by the administrator) in this case? -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
