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.
The pci-e 1x card work for U.2 and U.3 SSD,not work for SATA/SAS SSD.
The speed and other properties is not changed,only form conversion interface.Transparent to the operating system and does not require any software drivers.
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.
This PCI Express card expands the PC by one U.2/U.3 SFF-8639 interface.It can be connected e.g. the U.2/U.3 U3 PM1735 Series SSD.
