This is a low power home file server I built from a raspberry pi and two USB drive cases. I’ve mapped it as a network drive on all of my home computers, so we have one common repository for files, documents, and pictures. It’s set up with two hard drives, one a mirror of the other. I’ve had it running for 3 months without any problems.
The whole unit is not much bigger than a coffee cup, and my measurements show it uses between 6 and 7 watts of power when idling (which it usually does).
This is a fabrication exercise rather than a software tutorial; I will show how I modified the drive cases, but not how the software is set up. For that phase, I recommend reviewing
