    Sounds like a good plan. I did something similar with my previous setup.

    I know for sure you can resize partitions with Disk Utility, did it several times with HFS+ formatted drives, but I hadn't had the chance to do it with APFS. APFS drives should work just fine though, or even better since APFS supports containers which are supposed to be easier and safer to work with.

    Obviously, do that after you've successfully migrated all your data to the new drive, or make sure you have a full backup, you don't want to take your chances with that.

    Let us know how your new drive works!

    Hello guys! Sorry if I answer only now, I didn't have time. I received my SSD Samsung T5, and I could install both MacOS Mojave and Linux on it. With the internal HD of 1 TB, I left 150GB with the first MacOS Mojave in order to have a backup in case something happens, and I left 850GB just for data. I chose APFS for this 850GB and for Mojave on external SSD. I'm really glad with the result, I'm inside the system in 15 seconds at the most (from the Apple Logo), and I can see the difference when I use the OS. I have no problem with APFS, the system doesn't show any delay at all. If you have any question I'm here :) I'm glad I didn't open the Mac, this external HD is so small and fast :D
