I could read several QIC-02 tapes after ~15 years (~'90 to '05). I tried again after 20 years and the tapes jammed. I guess the tensioning system lost it's elasticity. HDDs I had from ~1997 started to accumulate bad sectors after ~10 years. HDDs from 2010 are still good today, but just to be safe I'm using RAID5 with different batches of drives and 2 offline backups. I saw a 5.25" 360K floppy that was used daily to boot a 8086 until 1997 (I have no ideea how old it was, but it really was a 360K, not a 1.2MB, re-formatted low density). I have early 1990s 3.5" 1.44MB FDs that still work. Late floppy disks were mostly singe-use bad. The biggest problem with tapes was the ISA-based controller. No such troubles with HDDs. PCIe to PATA or USB3 to PATA are still available today. I wonder how long QLC SSDs will hold data? Is it turning into a "buy new - copy old data - keep 1 year - repeat" ?
