You say that as if bit rot is the black plague of data storage. In the past 20 years I have encountered 'bit rot' with NTFS... not once. I have encountered bad blocks and replaced drives once in a while by monitoring SMART status, which probably prevented the rot. It is definitely great to have protection against it, but to call other features window dressing when others have used them more often than they thought of checksumming feature is not objectively fair.
- usefulcat 8y agoIn the past 20 years I've lost multiple files to bit rot on NTFS. In my opinion, the primary purpose of a filesystem is to reliably store data. Checksumming is not particularly complex technically, does not impose significant run time costs, and allows the filesystem to at least detect when data has been damaged. Unless there's some other very compelling reason to not do checksumming, it's reasonable to consider it's omission to be a de facto bug.
- Demiurge 8y agoDoes this mean ext4 is bugged too? We many filesystems with this bug, and we lived with this bug for a while. Anyway, I don't disagree on the technical cost/benefit analysis, but still, unfair.
