Braggadar: I'm not only referring to CDs, but to larger media. If you haven't ever owned a large DVD or Blu-Ray collection I've got news for you: it's much more common than you'd think and although handling and storage does play a role sometimes it seems to be completely random. It's particularly bad for dual-layer discs.
I have around 300 physical games, mostly comprising PS2, PS3, PS4 and PS5 games, with a few PC games. All of them still work fine. I have a copy of NFS Most Wanted for the PS2 that I ruined as a kid, and not because of age, but it still reads sometimes.
I did indeed hear that movie discs sometimes do go bad out of the blue, but I was mainly focusing on game discs. And when it comes to games, it's a lot harder for it to happen for a simple reason: the game printing factories vary a lot less in quality compared to movie discs. Game discs are made in much better factories overall, while movies could be made just about anywhere. If you grab any PS2 disc (which is a DVD) and compare it to any movie DVD, you'll immediately notice the difference in quality.
Braggadar: As for the "but you digitally backup the physical copy itself"... you're basically saying "physical is better because you can make a digital backup in case of failure".
Correct, and I do think it's a great point for physical media.
Braggadar: Furthermore - depending on your jurisdiction and the terms of the licensing agreement such copying of the original media
might be against the law.
I'm not gonna argue too much here because I might say something that could be wrong. But as long as you're using said backed up copy for personal use exclusively, in most places you should be within the confines of the law. It's only when you distribute it without authorization that you're breaking the law.
In addition, a lot of GOG games are just installed physical copies without DRM, and some games here just straight up include a raw disc image of the game. For example, Tunnel B1 [url=]https://www.gog.com/en/game/tunnel_b1[/url] includes not only a disc rip of the DOS version of the game, but it also includes a proper redump.org grade dump of the PS1 version of the game. And GOG isn't breaking any laws here. So you shouldn't be either if you back up a disc for yourself while you still own said disc.
Braggadar: But claiming the physical disc will last longer than the average digital file backup because you can make a digital copy of said disc is a little ass-backwards, isn't it?
I didn't say that. I said that game discs last more than HDD's. If you copy over your game to a new HDD after a few years, it's a new HDD, so you can't really say your game lasted longer on your HDD, because it's a brand new HDD.
However, technically, once you back up your physical copy digitally, it can last as long as any frequently backed up DRM free copy.
