We do a pool of mirrored disks with fast SSD's for our ZFS caching.
Performance is fantastic and, as I mentioned in another reply, the
rebuild time of a failed drive (or a resilvering when I upgraded all of
the drives on the fly without downtime) is way faster than any RAID I've
ever worked on before (which is quite a few in my career).

However, even if performance wasn't great we would still probably be
using it because of the tooling around ZFS. We utilize a lot of the
tools it provides for shared file-systems, backups, compression,
de-dupe, ect.

Never used ZFS on *BSD. I've only used it on SL7 so I can't say anything
about an OS difference.
