I have a Verbatim BDR that was branded M-DISC. I burned a bunch of data and put a file full of hashes for the files on it when I started using BDR's as backups to get a feel for when my data might be at risk. I use it as a coaster on my desk. My kids have carried it around with sticky fingers. I fidget with it and flex it a good bit. I've left it on my patio table outside for months at a time. I wash it in the sink with dish soap from time to time to clean it and dry it with whatever hand towel is in the bathroom. I abuse it to see when it starts to lose data.

I've been doing this now for a bit over a decade. It hasn't experienced any noticeable corruption yet on ~22GB of data, but I'm not doing any deeper reads on it. Spot checks on my properly stored discs have also not lost any data.
