4k sector disks

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

Is there any special configuration needed to use 4k sector disks
efficiently ?

I have a couple of SATA drives with 4k sectors, the disklabels for
them give a sector size of 512 bytes but 'atactl identify' shows
the true sector size.

I used 'newfs -S 4096' on one of them, a new SSD, but am wondering
whether to copy stuff off the other one and repartition.
