I have changed the format of my posts slightly from now on because the old format had a neatly swipable picture album but the text had to go into the comments because Reddit does not let me have text and neat pictures but it's harder for people to find the comment so I decided to put the text in the post but the images won't be neat anymore which is a small price to pay but well worth it, apologies for people that have trouble seeing my post from now on but I also had trouble seeing the last photo of all of my posts so I hope this new format fixes it for you.
The first picture is just a general image of all of my data storage formats up to now
The second picture is my reorganizing of the standard optical media, I already had a few because my dad used to burn copies of movies and games so I went through them and took the ones I didn't have yet, I also added a DVD - and + RW because I used them extensively for moving files to my data storage media testing computer which is an older one without USB, don't worry if you don't see a specific optical disc on there because I have a lot more silhouettes and discs to hang up, these ones do not have a 3.5" counterpart and will be put up on the side to the optical discs with a minidisc counterpart, please do tell me if there are any other standard sized optical discs that does have a minidisc counterpart.
The latest addition is DVD-RAM, it's an optical disc that behaves like a hard drive that enables drag and drop, you can add and delete stuff like it is a hard drive but it's a slow one, it was mainly used to store lots of data and move it to printing presses, it was also a reliable media because it could last up to 30 years in a good environment, it's also the only consumer optical only disc to have hard sectors, the other hard sectored discs were for professional data center use and usually were big disc cartridges, the hard sectors allowed for the disc to be multi session and its low 2KB block size reduced wasted space allowing you to pack lots of data on one disc, the 5.2GB on the shutter is a misnomer because it's actually 2.6GB on one side and both sides add up to 5.6GB like a 5.25" floppy disk.
I am not making as many posts as I used to because my media which is tested and guaranteed (unless it’s very obscure {example ZX Microdrive} or the drive is too expensive {example LTO}) just isn‘t selling quick enough to be able to make more often posts, if they did, I would be making posts much more often.

Standard sized optical discs and their minidisc counterparts, I have 2 minidiscs (3 if you count the audio magnetoptical minidisc) and I find them really cool
