alt Hacker NewsThat traditional wisdom is wrong. ECC is a must-have for any computer. The only reason people think ECC is mandatory for ZFS is because it exposes errors due to inherent checksumming and most other filesystems don't, even if they suffer from the same problems.
I'm curious if it would make sense for write caches in RAM to just include a CRC32 on every block, to be verified as it gets written to disk.
