My recipe for large files: 3 copies. Right now, 1st copy on external 8 to 16TB NTFS desktop hard drives, and 2nd copy on 14 to 16TB internal ext4 drives. Theses drives I power up only for copy purposes, once a month or so. At present time, my drives are 5 to 7 years old, and still good.
Main working copies I keep on 4 to 8TB NTFS SSDs (mix of sata and nvme), plugged into a PC I'm using regularly, but intermittently.
