Try Alt+Wheel

For flexibility and size I like external m.2 enclosures. I have some from Sabrent, Orico and Rosewill. Of them all the Rosewill is the smallest, has the nicest build quality, and seems to dissipate heat the best.

So I would recommend a Rosewill 9SIA072GJ92919, and add an NVMe SSD of your choice.

I think your MacBook is Thunderbolt 2, so you won’t get full speed but it should still be plenty fast. And this enclosure will give you TB3 speeds if you upgrade your PC later.
