I currently manage four NASes (two primary, two backup replicas). Only one has ECC RAM. And I'm okay with my setup. ECC is great to have, but it is oversold by some as being absolutely required for all storage devices, IMO.

For truly important files (photos), I’ll take the slight added expense of ECC for a little more peace of mind that old photos aren’t being gradually degraded with every resilver or scrub.

Good point about ZFS. Having more than one copy helps too. ECC is great when possible.
