I have HDDs (spining rust) in my desktop that are 10+ years and still running fine. I had older SCSI UW-320 disks that were running 20+ years until well, started to give I/O errors. Workloads are low here (mostly read). So I imagine it is doable to do HDD with low density and high grade components that would last 100 years. Interesting challenge imo.
