U.3 is a Tri-mode standard, building on the U.2 spec and using the same SFF-8639 connector. Itcombines SAS, SATA and NVMe support into a single controller. Where firmware support is available, U.3 can also support hot-swap between the different drives.

U.3 drives are still backward compatible with U.2, though—the U.3 drives determine whichhost type it is insertedinto(by using different combinations of HPT0 and HTP1 being open or ground), and configure the data lanes on power-up.U.3 drives can still act as dual-port NVMe drives in supporting systems.
