Has both an M.2 NVME Drive slot and M.2 B-key SATA slot.    The NVME slot works great however I lost connection to my SATA slot SSD at some point.  After reformatting it showed up again but then disappeared a second time.  It may be a drive compatibilty issue but the SSD works fine in another enclosure.   Just assume the SATA slot does not work properly.  Everything else functions as normal.
