Same, but I also discovered a wonderful bonus in the difference between True ECC DDR5 and just the on chip BS stuff.

ECC DDR5 boots insanely fast since the BIOS can quickly verify the tune passes. This is even true when doing your initial adjustment / verification of manufacturer spec.

Do you know a system that does this? Looking for this too

btrfs and zfs

ZFS, Btrfs, or SnapRAID in a chron job (not a file system, but accomplishes something similar).

ZFS is the “gold standard” here

SnapRAID is awesome, it's been bulletproof in recovering multiple failed drives for me, but note that you have to have your sync and scrub operations appropriately configured to get bitrot protection.

I have had good experiences with SnapRAID as well. I use this script to run it (in a Chron job), which is highly configurable:

Came here for this comment. I wouldn't run a NAS without ECC.
