If you avoid QLC drives, keep it at a reasonable temperature, and don’t use a drive that’s had a large number of write cycles, it will be fine for a year.
I would definitely read everything on the disk yearly so the controller can detect any weak blocks and rewrite them though. A good way to read everything would be to take a checksum. You can then compare that to the previous checksum to make sure the files haven’t changed too.
Mechanical drives have issues with long term storage as well. When hard drives get older, sometimes they will just refuse to spin up after sitting for a long time.
