alt Hacker NewsI still use optical discs for my personal backups and have done since 95. My biggest concern is whether I will still be able to buy new drives and blank media in 10, 20 years. Or physical media at all...
Please do not say LTO tapes. The drives are huge, noisy, expensive, and they have a very quick deprecation policy (new drives cant use old tapes).

New drives must read and write the previous generation of tapes and they must read the tape generation that was before the previous.
The larger issue with tapes is that the small magnetic domains don't hold data as long as the mechanical changes in optical disks.

You can get 5.25" bay drives.

Sure but old drives are widely available at low prices.

Literally every single reply to this comment mentions LTO; never change HN.
You can still buy brand new LTO-4 and up from a brief search - I think due to the enterprise use cases it’ll hang around longer than any other format. Tape existed before the HDD; it’ll be there watching HDDS pass away into the ether too. Probably a few tape drives on the Starship Enterprise somewhere.
More seriously; you can buy used lto-7/8 for very little these days, and the tapes are extremely cheap per gb. The drives are somewhat loud; it’s not a beside device for sure. I’m finding it a bit of a pain to manage a good backup strategy with them.
