  • 3) U.3 is a Tri-mode standard, building on the U.2 spec and using the same SFF-8639 connector. It combines 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.
  • 4) To avoid damage to the device, ensure that the installation direction is correct. Does not support hot-plugging.
  • 5) U.3 drives are still backward compatible with U.2, though—the U.3 drives determine which host type it is inserted into (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.U.2 drives are not compatible with U.3 hosts.
