What are the rules of buying used storage?

I am currently expanding my Homelab setup, and want to buy a 10TB drive, for media storage. It's a Seagate Ironwolf disk, so perfect for the job. But, it's second hand. It was originally bought in 2019, but stopped being used after 2022. Only used for static storage, it's been booted less than 50 times. I can get it for 1/3 of the original price.

What do you think? Are there any rules about buying used storage I should know about before buying it?
