Hello 10 Inch Richard,   They are compatible. The part number  DXD9H  is valid on 16gen- R760, R660 and other 16gen. Part #:DXD9H Part Desc.:ASSY,CARR,HD/SSD,2.5,14G ASSY Carrier HDD/SSD, 2.5 Inch, Metal  
Are the Dell PowerEdge 16th generation SSD trays the same as the 14th & 15th generations?  The part number we have for the 14/15th generation caddy/slide is DXD9H. It doesn't seem to be the same but there is little to no information on it from what I have seen. Any help would be much appreciated.
