comment On which disk is a file located in a btrfs RAID-1 array/filesystem?
I really doubt if such too exists. If I were you, I'd ask the question directly to the btrfs-kernel mailing list. And if you do please - post their reply here. It would be easier to find.

It will rather be a list of hard disks. The file will likely be spread across many devices.

There is also usermode LXC. Whith it you can arguably get a pretty good security too, roughly comparable to KVM or even better. UML still is more secure, since it should be more immune to privilege escalation via kernel bugs.

To put it simply: one layer of ECC simply isn't enough on nowadays' storage sizes. See the link on the @SteveWills answer.

It is all about the errors that gets uncorrected by the disk's firmware. If the firmware didn't correct for the errors, the error rate would be many, many, many orders of magnitude worse than 10^(-14).
