An SSD docking station is a great idea to easily utilise replaced SSSD drives

This is an interesting idea to use those SSD drives that you may have upgraded, because if an SSD drive is left for too many months without being plugged in, it can lose its data.

This is an easy way to plug one or more in and use it for ad-hoc storage.

It is true that a USB-C connector may have got much better speeds, but I suppose a USB-A connector provides maximum compatibility.
