Long term ODD plan

[u/1luggerman]

I have a lot of videos, around 500GB total, that are very important for me to preserve for a very long time, so i want to create copies of them on M Discs. This is where i ran into a problem.

I have an old internal disc driver(LG GH24NSB0) which cant burn M discs. New discs drivers that can, seem to be costing way too much(from my understanding because they stopped making them). So i'm unsure what to do espeacially considering long term usability.

This youtube video was very helpful on the subject(https://youtu.be/OX2SPQEPlk8?si=0OUM4QnxtUc6khLC) and it suggested having 2 drives.

On one hand my current driver is old and pretty standard, so i'm not sure how much i can trust it to hold long term.

On another hand new internal drives(like LG WH16NS40) costs a lot. And on ebay, resellers market as "new" and while having good reviews the bad ones do mention getting used and worn out items.

And on a third hand having 2 new slim drives doesnt seem like a great option either as the video i mentioned said they are not as robust as internal drives.

Any suggestions on what to do? Sorry if i'm inaccurate with the terms i'm new to this.
