On a very high level ZFS main thing compared to APFS is currently data integrity features such as checksums of the data to detect bit rot (silent corruption) and the ability to automatically heal the data (with enough redundancy in place).
It would be good to at least have the checksum capability in place to make one aware of bit rot silently destroying data. Hopefully there has been some improvements to the capabilities since the announcement last year.
- nkkollaw 10y agoDoes bit rot actually happen on regular computers? I thought it took years and it was mostly a danger for huge external hard drives. I'd rather have better SSD performance. I just personally never lost any data because I let it sit for too long.
- mveety 10y agoYes, bit rot happens all the time. Normally the drive its self catches and repairs these errors, but sometimes they slip through and become the filesystems problem. It doesn't really happen super often, but the fact that it happens at all mandates that filesystems that care about data integrity handle it.
