Use M-Disc media. It's said to last 1000 years. It's expensive and very slow to rip at the suggested 4x speed.
I've been very satisfied with them, and you just need a regular Blu-Ray drive.
Cheapest solution is an HDD + one more for backups. M-Discs for 15-17€ per 100GB are for the games you wanna take to your grave.
I mean they are games that i no longer have to worry about data corruption or loss. Like ever. And i can Will these to family & friends. The cost is easily worth that!
Yeah, normal burners are more like printers, where the write laser activates or deactivates a pigment which then either reflects or absorbs the read laser to represent 0/1. But that pigment can degrade over time, turning 1s into 0s.
M-discs are instead etched and iirc use constructive and destructive interference so the reader (which is the same reader as normal discs, just the writer needs to specifically support M-disc) reads the 0/1. It will also degrade over time, but since it's a thicker layer of difference, it will last significantly longer than a thin layer of pigment. And I bet that special m-disc specific readers could be made to read it again after it degrades to the point where the interference technique stops working, since an image could still show where the high and low points are, even if the waves don't align perfectly anymore.
In practice, I've found that the drive was way easier to find than the media for m-disc. Like most optical disc writers these days seem to support it but the discs are expensive af compared to non m-disc.
Though when I was going through my old burnt CDs and DVDs, I was surprised at how well they were holding up. I was expecting at least some read errors by now but everything has been fine so far.
Well, other than the data quality lol. Not like the readability of the file but stuff that took days to download back then would download today in seconds and a good monitor I got well after my early files was only 720p for its resolution. The data I prized as a youth is kinda sad today.
Verbatim Datalife HTL BD-R discs are supposedly made in a similar technology (some folk on r/datahoarder think they're exactly the same but idk). At the very least they won't have the same problem as DVDs (no organic dye) and they actually work out cheaper than half decent HDDs. I can get 25GBx50 cake for £30. I've only started burning them a year or two ago so time will tell if I lose my data :x.
blu ray in this economy?
You need an M-DISC BluRay drive.
Are tape drives still a thing?
Yup
If I were more serous I would probably get a couple of those. I remember it being part of our procedures at a gov office.
What about Verbatim AZO? I've heard good stuff about those, and they're not expensive.
Also, as far as CDs go, I've found that an old degraded player which doesn't read burned discs anymore but plays pressed discs will still play burned AZO discs just fine.
