alt Hacker News> You notice when things like your compressed files start giving CRC/checksum errors or your downloads don't match SHA-512.
And 9 times out of 10 (probably much more) it will be faulty storage, not RAM.
I'd say you are way overestimating impact of no-ECC.

...No? Faulty storage will almost always show up as I/O errors, modern storage generally doesn't want to send a block of data to the CPU if there is an error in it. If your bits are flipping, chances are it's RAM and not storage. Your storage already has ECC.
Some crappy flash drives might not do this, though. Seems to behave like a floppy disk at times.

You need the ECC RAM for your filesystem with integrity only then can you be confident you aren't going to be familiar with a concept like this happening 9 or 10 times.
