Silent Data Corruption Is Real
It really bugs me (and has for a while) that there is still no mainstream linux filesystem that supports data block checksumming. Silent corruption is not exactly new, and the odds of running into it have grown significantly as drives have gotten bigger. It's a bit maddening that nobody seems to care (or maybe I'm just looking in the wrong places)(...sure, you could call zfs or btrfs "mainstream", I suppose, but when I say "mainstream" I mean something along the lines of "officially supported by RedHat". zfs isn't, and RH considers btrfs to still be "experimental".)
