would be interesting how that M-disc looks - and reads - today 10 years later..

I 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).

> The drives are huge

You can get 5.25" bay drives.

I believe they are all 5.25in, some are just in a case. Even the library drives are just two 5.25 bays put together, a full height drive; vs. the much more common half height.

Sure but old drives are widely available at low prices.

This is true - I got a fiber channel LTO-8 FH drive off ebay brand new in the IBM packaging for less than 750$ Tapes are 60; so breaking even against 15$ per TB HDDs is pretty fast.
buildbot•34m ago
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.

Still using m-disc for family photo albums and having them in the bug out bag in case something goes wrong. Inexpensive and light. Such a shame the disk format is dying.
thomassmith65•49m ago
I agree, but it's worse than a shame: it's an indictment of the tech industry!

We have the entire planet storing all sorts of important business and personal data digitally - and no longer a good, common way to ensure it lasts even a decade.

For DVDs: Walmart still sells a USB reader/burner for $30. Also I'd bet something will be able to read recordable disks in the future even without drives. Maybe a super super high resolution (compared to now) picture can simply be used to get the data from it visually in 30-40 years.

IIRC, "M-Disc" branded discs stopped being "M-Disc"-spec at some point, but since it's quite a niche product that peaked (over?) a decade ago, it's hard to find any definitive information about this in 2026. It's a shame because I liked the format. I'd be glad to see any form of confirmation or correction.

If you’re talking about this post, it’s just someone who was misinformed. https://www.reddit.com/r/DataHoarder/s/cmxnECtgAv

> Verbatim clarified that these discs were advancements. The technical changes resulted in a different appearance and the ability for higher burning speeds, the changed media-ID was due to an adaptation with regard to other Verbatim products. Verbatim had already shipped the first modified media in early 2022. The data security of the new discs is not inferior to that of the old discs: Data should also last 1000 years, according to the manufacturer.

Cool, but the method of verifying the data (playing back the movie) seems non-optimal. The movie could have had some data corruption that went unnoticed.

Does anyone know the control disc used (http://www.microscopy-uk.org.uk/mag/imgsep16/m-disc-test3.jp...) was HTL or LTH?
