I’ve ordered yesterday an unused old external floppy-drive (IBM) and a set of floppies (Sony). More for fun than on purpose. By the way you need them everywhere where stuff remains a long time usable e.g. the older B747-400 or trains, plants and heavy machines and so on.
I hoped that SD-Cards replace them because the slip into a slot (other than USB-Thumbsdrives), have defined speed-classes and you can write on their outside what is stored on them. Cars, cameras, bike-computers and so on use them everywhere but computer manufacturers failed to built them in or connect them properly via USB (I refer especially to Lenovo which connected the card-slots via PCI which prevented booting from them…).
Honestly. I don’t like optical disks. They allowed for higher capacity but they were like multiple steps backward and a huge waste of material. Mostly one time writeable, a lot of material required, big form factor and writing them was also complex. Optical disks are like technology which should have skipped over? I even myself bought once a mini-disc player…wasted money.
Oh no, optical disk is superior - I can backup family photos to M-disk and shove it in a bank vault, and in 100 years it will still work.
Just like photos, I have family photos that are 60 years old. Digital photos of 10 years old are lost
How are you gonna store a video for 50 years? flash memory discharges, hard disks rust, upload to google drive and hope they don’t kill the service?
