The prices I’ve seen are about 100 € / $ though plus the two SSDs you need, personally I’d invest in external backup instead, that covers more data loss scenarios than this adapter.
If you just want to use it from your home computer / network you can run it locally, either installing it directly or in a container. You only need a server (or a way to connect to your home network) if you want to access it from elsewhere.
