BUILD UFS or ZFS for this hardware

[mervincm]

ASUS p7FE server board xeon quadcore 12GB ECC
2 x integrated in intel NIC Intel 82574L
6 x SATA 3G ports
1 x HP P400 RAID controller w battery backup
5 x Seagate ST000DL003 2000GB Barracuda Green
CC32 Firmware (4K) 6Gb/s, 64MB cache
1 x Seagate ST32000542AS 2000GB Barracuda Green
CC34 Firmware (512K) 3Gb/s, 32MB cache
1 x 32GB intel SLC SSD, 1 x OCZ Agility 4 256GB MLC SSD, 1 x 120GB Samsung 840 TLC SSD
APC UPS 1300VA

This is what I have spare on my parts shelf. Obviously I don't think all will end up in the NAS, but.

Requirements are
NFS for ESXi 5.5 host , only a few VMs
CIFS for Windows 8.1 Desktops
4-5 TB of usable space

My thoughts
-UFS is being dropped from FREENAS? so if I choose it I would be locked out of future bug fixes and features
-UFS would not be able to use SSD or all the RAM I have to any benefit.
-ZFS is exciting, but memory is on the low side.
-Barracuda Green with CC32 drives are known to be flaky in some NAS appliances, dropping out of raid even though healthy
-I ran them for at least a year w/o issue from the HP P400 card presented as individual disks via ESXi5i (RAID0,) with Windows 2012 storage spaces RAID 5 and de-dupe.

-one day will have money to replace the HDD and add RAM, but have no other use for these ones and I need 4TB of NFS right away. no need for dedupe or compression or anything like that, I have lots of spindles I think.

ZFS RAIDZ2 with 5 x 2TB on SATA ports + 32GB SSD on P400 for ZIL.

Without dedupe the amount of RAM should be sufficient for an array of that size. The SSD should also be more than big enough to act as SLOG

Thanks. I am going to try it that way then.
