The following should be the proper way to format this SSD with exFAT:

  1. Open Disk Utility.
  2. In the top-left menu, click View > Show All Devices. This reveals the physical SSD, not just its volumes.
  3. Select the drive itself (not the indented volume underneath).
  4. Click Erase. For Format, choose exFAT. For Scheme, select GUID Partition Map.
  5. Click Erase to finish.
