Using Old HDD as External USB backup

[bezkawno]

I have a 2-bay Terramaster F2-210 and at the moment I'm using a 5TB Seagate Portable HDD connected to the USB-A port on the back as a manual backup of sorts.

I'm looking at upgrading my capacity from 6TB to 12TB on the NAS and I don't want to throw away the old hard drives. I was looking at the Wavlink dock at the link below and wondering if I could connect this to my NAS's USB port as an external hard drive, the same way i'm doing now with my Seagate?

It does say that when two hard drives are connected to the Wavlink dock, they will appear as two separate drives, not one (if that makes any difference)
