U 2 connector is a combination extension of the existing sata and sas connectors which offer up to 4x pcie 3 0 lanes to a connected device.

Its purpose is the same as sata express to provide sufficient bandwidth for fast ssds. U 2 connector supports nvme standard protocol and pci e 3 0x4 bus which makes the u 2 ssd have a theoretical bandwidth up to 32gbps and have advantages of high speed low latency and low power consumption.

When intel unleashed it s super fast nvme ssd 750 it cam is two form factors one was a pcie ssd and the other was a 2 5 ssd which sported the all new but rather hard to say sff 8639 connector.

The connector for disks is totally different than the connector for motherboards and only a handful of disks for this interface exist. U 2 utilizes the pcie 3 0 x4 denotes four lanes interface just like m 2 the main difference is that the capacity for these ultra high performance ssds is not bound by a small. 1 sff 8643 36 pin x4 pcie gen 3 host connectors.
