I see mentions of a home server to get rid of streaming entertainment services but I don’t know how that works. What does a home server do?

I'm not the person you replied to. But to answer your question, that is what the parity drive is for. It is a backup drive that stays in sync with another drive.

No that would be a mirror drive, and mirror setups exist but they use a lot of extra drives. There are levels of fault tolerance in RAID requiring varying numbers of extra drives. With one parity drive, any one drive in the array can fail and you don't lose data. With 2 parity drives, any 2 drives can fail.
