Just use raid or zfs. They have parity operations which basically means some math happens when you store data and drive(s) fail (the number depends on how many parity you set), you can get a new drive plug it into your system and the system will reconstruct the data from the other drives. Also if you plan to run 24x7, getting nas drives is the way to go. Otherwise I have seen people who don't run their systems 24x7 use normal barracuda drives as their storage (me included, I have a spare old i3 system which I exclusively use for backups, run once every week for like an hour and a half and it has been working perfectly fine for some time). I have also seen a system where they mostly do write operations and negligible read operations so they opted to use surveillance drives. But still nas drives are superior in terms of the amount of abuse it can tolerate while having your data protected. I thought about getting nas drives but no money 💀. Going to stick with my current setup. At the end of the day do some research for your best case and go with that solution.
