Hi all, I have a very simple homeland which consists of just one thinkcentre mini pc. I don’t really need extra storage at this moment, but I think adding another disk for redundancy will be nice.

The problem is, the mini pc only has space for one hard drive. What is the best thing to do in this case? Is the a reliable way to add an (ideally, with space to add more later) extra disk to it? I don’t really want to get something like a Synology as I’m happy with the processing power etc. of this. Some way to expand the storage as directly as possible will be nice.
