But beware that many of the cheaper drives (eg Western Digital "EARS"
series) lie to say that they are still using 512 byte block but are
really using 4K blocks. This is supposed to make it easier to use
these drives with Windows XP, but it messes up performance in other
OS especially when using RAID with mdadm or ZFS.
