I'm the proud new owner of an HP Proliant Microserver N40L, and planning to upgrade the (obviously paltry 2 GB of) memory to the maximum of 16 GB. (Theoretically 8 GB is the limit, but empirically 16 GB has been shown to work.) Some guides advise that ECC memory is not that important, but I'm not so sure I believe this.

I've installed FreeNAS and am planning to add ZFS volumes as soon as my new hard drives arrive. Would it be stupid to skimp and get non-ECC memory for a ZFS-based NAS? If it's necessary, then I'll bite the bullet, but if it's just paranoia, then I'll probably skip it.
