Note that the majority of tests and durability claims about M-DISC (particularly about the special recording layer) are about M-DISC DVD-Rs. Although manufacturer likes to conflate them in marketing, it's not clear whether the M-DISC BR-Rs are any different than regular HTL BD-Rs.

Also apparently Verbatim are selling fake M Discs https://www.reddit.com/r/DataHoarder/s/cmxnECtgAv https://www.reddit.com/r/DataHoarder/s/cmxnECtgAv

  Manufacturer response: Verbatim clarified that these discs were advancements. The technical changes resulted in a different appearance and the ability for higher burning speeds, the changed media-ID was due to an adaptation with regard to other Verbatim products. Verbatim had already shipped the first modified media in early 2022. The data security of the new discs is not inferior to that of the old discs: Data should also last 1000 years, according to the manufacturer. How was the 1000-year lifespan for M-Disc media calculated? If there's a chemical process for simulating centuries of media degradation, then it could be applied to the new Verbatim media to evaluate their longevity claims. There must be an industry association which licenses the M-Disc trademark and disk identifier? If the Verbatim media is legit, they can be issued a unique, approved disk ID by the M-Disc trademark licensing body.

    Either the original M-Disc BDR marketing was bullsh*t or this response is. Whichever way it is, it doesn't make Verbatim look good.

      Did Verbatim ever look good? Afaicr, the writable optical media market has been race-to-the-bottom since ~2000.

        None of my Verbatim discs (at least >20 recently accessed, maybe >200 over the years incl. the ones I have given away) rotted/corrupted after a decade. I don’t think they’re bad.

  Actual user here. Some of them seem to be unreliable (I have those 100GB discs) and not like the older batches I had. DM me for stats if you are interested in knowing what happened. But they're not fake - apparently they got bought out and the new media IDs belong to them. Verbatim 25GB M-Discs are great. Have an archival copy of my files in addition to my NAS stuff. The important files are often small, so I use regular these smaller capacity M-Discs for them.
