I had some CD-Rs that rotted within a few years. I was devastated, because at the time CD-Rs were hyped up as the most durable of any consumer media, and storage was expensive. I had tons of stuff that was ONLY on CD or DVD. That’s how I archived everything.
There was an old site that did a comprehensive analysis and ranked different brands of CD-R and DVD-R discs into tiers. My main takeaway at the time was Verbatim or bust. There were some other brands that got discs from the same manufacturer, but not consistently so it was something of a gamble. IIRC Sony was one of the better ones, but Verbatim was the safest choice.
I can’t say I’ve tested any of my old discs in the past 10 or maybe even 15 years. I copied my most important data into newer media, but I still have a ton of discs I should probably clone to my NAS. One of these years…
Then came M-discs, which as far as I know are still considered legit. They never really caught on, and production has either halted entirely or is at least limited. I never used them myself.
I always bought the cheapest discs for backing up my media and out of maybe 1000 disks, checked last year, only 15 or so were either partly or completely unreadable
The last burnt CDs were in 2k2, I just kept em on their spindles on my bottom shelf (not protected any more than that thru hot and cold) and all but 15ish were toast. Might have gotten lucky
Humidity and UV are murder on a lot of things. Pressed optical media will generally las a lot longer than CD-R if for nothing else but the top layer over the reflective foil that’s missing from some cheap recordable disks. The error resiliency is a factor to thin of too. If you miss a few bits in a picture or audio recording it won’t do much, but in a executable program it could prevent it working at all.
When I was younger, I bought a fair bit of music CDs, mostly for the sake of collecting. To this day, most are still unopened in their original plastic wrap. I no longer have a disc player in any of my computers, nor any functional discman left in my possession, so listening/ripping them is probably never going to happen.
Sometimes I see people complaining about digital versions, but looking back, it probably really don’t matter nearly as much for vast majority of the cases…
