-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZFS is lovely, but a bit of a pain to configure, and effectively unsupported on Linux - so you need FreeBSD for your fileserver. Which may be a degree of complexity too far. LVM is not as fantastic, but also very simple.
For a simpler solution I'd go RAID 10 - 4 2TB disks, gets you redundancy and striping for a total of 4TB, which should be plenty. If you need to upgrade, you can add another pair of disks.
