Hard drives are affected by bit rot even when not in use. A disk check every six months would help, but is not a guarantee against data corruption or loss. M-DISCs are physically etched, and should last around a lifetime to a thousand years, depending on who you believe. The catch would be being able to read it in the distant future (in other words, if you’re using M-DISC as a backup solution, you should also have a backup disc drive).
M-discs don’t rot, theoretically they’re one of the best consumer long term storage mediums. I think the practical issue with them on a super long timescale is keeping a functional reader if blurays fall out of fashion.
M-Discs are just like Blu-ray storage. However, they are not re-writable, instead being physically engraved with a laser. They are marketed as lasting 1000 years. Get yourself a nice Bluray-writer and you’re all set.

woah woah woah, Mr. Namedrop. What is this, now? 100GB RW Blu-rays? $57 for a pack of 6?
$57 for 600GB
$100 for a 4TB WD Red
That implies it’s powered. Would it last as long as cold storage? (with running disk checks every six months)
…this is so offtopic, but I must know.

I’d need roughly 15-16 packs to do my entire archive atm, which is nearly $860.
…buuuut, I also see value in doing something like this over time. Say, I buy a pack once or twice a month, back up some data.
Yeah. In my case, I’m mainly only doing this for irreplaceable data, such as documents and photos.
You would have to weigh disk rot vs hard disk mechanical component failure.

For a WD Red? Get that shingled magnetic shit out of my NAS.
