Hello. This might be a bit of an uncommon use case, so i haven't been able to find much info on the internet. I'd like to make a backup copy of my (videogame) cd collection to a more modern form factor (my computer doesn't have a cd reader). Instead of one big hard disk, I would like to dedicate an individual "device" to each game/game series, so storage space of around 1GB to 100GB, possibly in an easily stackble form factor. I know that CDs are perfect for this, i know i should just get an usb cd reader (i will), that's what all the search results said. I was wondering if there is any other medium that's suitable for this. USB sticks and SD cards fit every need, except they apparently won't keep data reliably when unpowered for years.
Sorry if this is a stupid question, or this isn't the right place, but i haven't had to deal with a similar issue before ( i just copy all my other stuff to normal hard drives, but i wanted to keep the collection feel for these games), so feel free to kick me towards the right direction if I'm missing something obvious.
