People have been running Ext4 systems for decades pretending that if Ext4 does not see the bitrot, the bitrot does not exist. (then BTRFS picks up a bad checksum and people scold it for being a bad filesystem)
ZFS made me discover that my onboard SATA controller sucks and returns bad data occasionally under heavy load. My computer cannot complete a ZFS scrub without finding errors, every single time.
Ext4, bcache and mdadm never complained about it, ever. There was never any sign that something was wrong at all.
100% worth it if you care about your data. I can definitely feel the hit on my NVMe but it’s also doing so much more.
