I've done only tests using disk staging with JBOD and SAN attached disks.

UFS performed pretty well.
VxFS was a bit slow on clearing image files, but that wasn't a huge
problem as the image cleanup didn't always happen when I was trying to
write new ones.  Since it was VxFS, I could manage it using our standard
tool set and I knew it would most likely survive a host crash and not
corrupt itself.
ZFS had a lot of overhead that my test system didn't appreciate, but did ok.

If I had a faster system, performance might be a non-issue, and the
reasons for picking one would be for the feature set.
