Raid doesnt even protect against bit rot either. It doesn't matter how many disks you write to even in a raid one array you are still vulnerable. Unless you have a high end raid card that does block level checksuming your raid array will not go back and verify previously written to data is still correct. If it does have checksuming it still isn't smart enough to know which drive is the is correct and will lock the array in the best case.
ZFS pools do checksumming, snapshotting, etc.
As well as BTRFS and ReFS
