> Only buying CMR surveillance-class HDDs now for my backups. I have no way to confirm if this is true, however someone years ago told me that surveillance drives have inferior error correction and are optimized to not block recording in case of errors because they work on the assumption that you are storing videos, therefore if you miss a frame that's not a big problem if the rest of the file is fine. That of course would be a big issue in case of other data, especially if compressed. Again, no proof of that, but it's enough for me to avoid them for archival until I can be sure the above turns out as untrue.
