How Important is ECC Memory?

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

Anecdotal evidence, but I have been self hosting for 3 years and never had a single problem without ECC memory.

I think the thing is if you are serving thousands of requests constantly like a "real website" and/or have financial reliance on it then ECC memory becomes a huge ROI draw. If you are running a media server + a few services for one household, ECC memory is very overkill in the vast majority of cases and you won't see a difference.

For what i know DDR5 comes with ECC by default, so this won't be much of an issue in a few years.

It is not exactly ecc, you should check it out, I don't remember what was different

It's not end to end, it corrects the bits in the cell, but if the data is corrupted on the wires you're screwed.
