Interesting that it looks like Blu-Rays in all forms have much shorter longevity than the preceding DVD and CD formats. Presumably due to tighter tolerances required to fit more data on the same platter size? I had switched to large format 50-100GB M-DISC BD-Rs a few years ago, but to be honest I'm often too lazy to bother with the process of burning discs for offline storage. I should probably upgrade my NAS/external HDD&SDD stack again. I would advise anyone going the NAS route to think carefully and read reviews on RAID devices. It's probably safer & easier to keep 2 copies in 2 formats on 2 different media in the end. I have had numerous consumer grade NAS RAID devices fail to the point I almost find it an additional failure mode rather than level of safety. Fragility of consumer grade RAID reminds me there's a reason our employers hire storage engineers!
