Home Forums Peripherals & Multimedia Peripherals Internal HDD shelf life?

I have a shelf full of old 5 1/2" spinners that I use for archiving purposes. I used them in my Mac Pro until their warranty period was over, then moved them to the shelf where they sit unused for months on end.

My question is, will they last forever in such a situation, i.e. being plugged into a dock and run for five minutes, then back on the shelf and unused for another six months?

They still get usable readings from DriveDX. Three of them are read only, no need to write to them anymore.
