What other filesystems have checksums for data? Last time I looked, after a silent SSD failure that I only noticed because some .so files were affected, the only options were btrfs and reiserfs (I think ZFS required a custom kernel at that time).
The incident was really eye-opening in how fragile was my data: if .so files were not affected, I would have continued to use the system and erroneous data would silently be propagated to backups.
