    According to this site the average lifespan of the cheapest type of bluray is 5-10 years. So a personal backup with makemkv (and maybe handbrake) might not be a bad idea.

        True. I missed that. With 10-20 years the general point still stands though. There should be quite a few movie blurays out there that are close to the end of their life.

          It’s based on the same stuff as CDs and DVDs.

          I don’t think they last forever, but if the CDs and DVDs aren’t failing in mass numbers yet, I don’t see why the Blu-ray discs would be.

          Estimate for CD lifespans was in the 100 year range, but the only way to really put that to the test is to try them in 100 years.

          How they’re stored probably plays a major role as well. Most of mine are just stored in my living room in the boxes they came in. If you leave them lying in direct sunlight, or attics and garages at unusual temperatures and humidity levels, they’ll likely die a lot sooner.

            FWIW, I have some CDs that are pushing 40+ years at this point. They work fine, scratches and all.

            In my experience, CDRs and other record-able media can’t handle a single summer in a hot car. Mistakes were made. If you have your hands on anything like that, I agree: focus there first for your data hoarding activities.

              Yeah, definitely had a few CD-Rs die in the car. We don’t normally have particularly extreme weather in the UK so they last a few years normally. The combination of CD player heat, engine heat and summer heat makes them the temperature of a hot drink. They don’t like that.

      You’re talking about writable discs. Normal blue-ray discs have a much longer life expectancy than most other mediums including HDDs. Standards and manufacturing have improved too. Modern discs have a life expectancy for at least 50-150 years.

      I have a collection of over 300 discs. 100 of them are 10 years or older. None of them have failed on me. And I don’t have a temperature controlled room or anything like that. A lot of HDDs have failed on me during that time.
