I just cant find any reliable and unanimous infomation about this topic: What really is BEST storage for LONG-TERM data archive / storge? I mean really long time - let's say 30-50 years, is it even possible?
I red that:
- NAND Flash Technology - Flash Pendrives, ssd and other flash storage is bad choice due to physics around electrons which i dont know much about.
- Magnetic media - Olschool HDD are better than ssd but still degrades in couple years - that would make it possible option only if having 2-3 backups of same data in case of one fails
- Optical Disks - It seems discs like blu-ray have really long-term durability if handled well and there seem to be something made just for that - M-DISCs but i dont know if that is really good choice - anyone have experience with it?
- Tape catridges - not sure how really durable it is but it can be writen only once and is quite problematic
I really need to know best options that are available right now. I wont even consider cloud storages for numerous reasons. Let's talk about it!
