Re: deciding UFS vs ZFS

UFS with SU+J surely, gjournal is now depreciated in 9.x onwards

Its your choice of course, but the spreading around argument doesn't hold
water as all file systems will do that over time, and what you are implying
is you will only ever use a small % of the drive. Checksuming is never
useful until is saves your ass, pretty much like house insurance. You don't
needs it and it hurts you to have pay it, but all of a sudden when you do
need it, you are very grateful you did have it. Plus you will get early
warning on drive failures, rather than just failures (assuming you did
copies >1, on a one drive system).

zfs will happily rocket along with 16gb if its a desktop system
