As soon as they became easily available, I've bought a no name USB floppy and managed to read and store lots of stuff I still had on decades old floppies that I found at home. I could read just about everything, while many more recent CDs and DVDs I had burned years later, some containing important stuff, became unreadable after even 5 years or less. I also lost projects I burned in multiple copies on branded media and stored properly; that made me ditch completely the optical disks on all my computers since like 2006.
