How Important is ECC Memory? (sh.itjust.works)

Hello fellow selfhoster, I was wondering how important it is to have ECC Memory. I want a server that is really reliable and ECC memory pops up as one of the must haves for reliability. But it seems to me in my research that it is quite expensive to get a setup with ECC memory. How important is ECC memory for a server (I rely on).

So far I have been rocking a Raspberry pi 4 which has ECC memory

For large storage, ECC helps a lot for avoiding storage corruption. In combination with a redundant architecture in zfs it is almost bullet-proof. (Make no mistake, redundant storage is no substitute for backups! You still need those.)

One option is to use comparatively old server hardware. I have some pretty old stuff (around 10 years) that uses DDR3 RAM, which is dirt cheap, even with ECC (somewhere around 1 €/GB). And it will be fast enough by far for most applications. The downside is higher power consumption for the same performance. The Dell T320 I have with eight 3.5" SAS disks and 32 GB RAM uses some 140 W of power, to give you a ballpark figure.

Yea I have been trying to avoid high power consumption as power is quite expensive here. I think for my case non ECC + ZFS + backup will suffice. Thanks!

I don't believe ECC uses noticeably more power
