Note that the shelf live of many types of CDs and DVDs isn't all that long and you shouldn't rely on them to preserve things. Some will be unreadable in less than a decade.
It varies a lot by materials used (Table 2, also note the paragraph preceding it): https://www.canada.ca/en/conservation-institute/services/con...

If I were going to buy a large archive of software, I think I'd want it spread across multiple discs, even at the expense of having more physical media.
CD-Rs, of course, have not held up as well.
Most people, nerds and otherwise, stopped using optical media for sneakernet years ago, and for good reason: you can buy a 5-pack of 64 GB USB 3.1 flash drives (which hold more, and are faster than, a 50 GB BD-R) for $23 on Amazon.com.
For comparison, a 25-pack of 50GB BD-R discs will run you $45, and of course that doesn’t include the drive. It’s still less expensive per GB, but it’s also far less useful because you can’t really share a burned Blu-Ray disc with anyone the way you can share a USB disk.
Edit: A quick search shows some on AliExpress for $0.99.
TL:DR; fake disks have controllers hacked to report 128GB or whatever, writing to them seems to work and opening the file would give you the first part of the file (so you can see the start of the movie or the song or read the first part of a text file) but the rest of the file will not be there...
If I was in a position of offering something of roughly 100 GB on physical media, I would spend more effort looking into it, but would expect something of roughly that price to be available.
Nobody can buy 128 GB of flash for $1. They are fake, and will eat your data.
Gee, I wonder if there's an online archive somewhere...
Most PCs could boot off them starting long ago.
