@chris I tend to buy my hard drives from Canada Computers (https://www.canadacomputers.com/en/). All told, I have about 20 drives in my home office, mostly spinning platters. My last few drives were in the 20-22TB range, and so far, they've been reliable. I flip between Seagate and Western Digital; mindful of the warranty differences.

Ideally, you want three copies of important data, so two local copies and one remote. If you have specific questions, fire away!
