gmirror disks vs partitions

[Josef Karthauser]

A poll for opinions if I may?

I've got a few gmirrors running on various machines, all of which
pair up two drives at the physical level (i.e. mirror /dev/ad0s1
with /dev/ad1s1).  Of course there are other ways of doing it to,
like mirroring at the partition level, ie pairing /dev/ad0s1a with
/dev/ad1s1a, /dev/ad0s1e with /dev/ad0s1e, etc.

Apart from potentially avoiding a whole disk from being copied
during a resync after a crash, are there any other advantages to
using partition level mirroring instead of drive level mirroring?
