I'm doing this since about 6 years now with all of my files and I never experienced any silent corruption. I also regularly experience MD mismatch_cnt effects on RAID1 with ext2/3 filesystems with heavy file removal/creation load (even before MD implemented its self-check features - I cmp-ed and corrected them manually before) and they all seem to have been related to metadata, i.e. inodes.
