I have yet to find a conclusive analysis on how well RAR with recovery works for different failure modes.
I mean I can guess it works pretty well for single-bit flips, but how about burst errors, how long can those be? Usually you want to have protection from at least 1 or 2 filesystem blocks, which can be 4 or 8k or even more, depending on the file system. How about repeating error patterns, data deletions, etc.?
