[SOLVED] T5 ssd and magician issue

Solution
Samsung Magician will run its benchmark tests against my WD SATA connected HDD, but the same tests are not supported for my USB connected WD/HGST drive. Therefore I think the issue is the interface, not the drive itself.
It says right there that it's unsupported.

The issue might occur if your SSD drive is not added to the supported list. If you have a brand new Samsung SSD model, Samsung Magician utility will not recognize your drive until you update the application to the latest version.
