Recommend me physical backup storage solutions

Current Events

I have a 2TB seagate portable drive that's about 8 years old, it's having problems with erasing new files lately and i'm getting nervous.

Probably 5-10 TB would be good, longevity is important to me but idk if there's any brands particularly known for that.
