SABRENT USB C NVMe Enclosure & Reader, Tool-Free M.2 PCIe SSD Case for 2230-2280, 10Gbps USB 3.2 Gen 2 Adapter, Aluminum Cooling, External M.2 NVMe Drive Enclosure (EC-PNVO)

Something like this should work to connect the 2nd SSD to your laptop while your moving the data over https://a.co/d/0hErUUaL There are cheaper and more expensive ones, but id recommend a decent name brand (which SABRENT is)

https://a.co/d/02g8QIuo Sabrent going for the same price (ok 1 cent more) and cools the SSD much better than this one.
