Whats the difference between ext drives attached to server vs attached to my mini?

If you plug the SSD directly into the M2 mini, it would be much faster, since USB-C is 5-10 or even 20-40 Gbps. That is the theoretical speed of the bus, the actual SSD will probably be much slower.

If you attach to the server, you are most likely limited to 1 Gbps assuming you have 1 Gbps ethernet, or if you have WiFi, you could have a slightly different speed. In either case, it will be slower than attaching the drivers directly to the M2.

My advice: sell the 2014 mini and use that cash for something to make your M2 better. Simplify, don't overcomplicate your life.

Well, all the ext SSDs I have are connected via USB-A so I totally get the speed issue. As for selling my 2014 mini - I'm wondering what I might get  with that money to make my M2 better? Maybe a Satachi hub? Any other ideas?
