Going with a REAL RAID box this time

I've been running a pair of 5TB USB3 drives attached to my PC. It works but I don't like everything about it.

I decided to get a real NAS box to put it in, and I've had my fill of half-assed solutions, so I went ahead and got a Synology DS416j.

Now I just need to back up all the data on those drives so I can slot them into the box when it gets here.

I probably need to go with an actual network cabinet so I can fit all this stuff in. The swing down from the ceiling works but it's not fantastic.
