The u 2 sff 8639 standard is pretty unique.
U 2 ssd connector.
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.

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.
On the motherboard u 2 is a double decker connector that receives a similarly double decker cable from the ssd.
The connector for disks is totally different than the connector for motherboards and only a handful of disks for this interface exist.
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.
Its purpose is the same as sata express to provide sufficient bandwidth for fast ssds.
It uses up to four pci express lanes and two sata lanes.

This connector will now be called u 2 given it s similarities to the current m 2 connection which is currently used in small form factor devices and.
On the other end a much wider cable plugs into the ssd for the u 2 multi lane.
The enterprise ssd form factor was released on december 20 2011 by sffwg as a mechanism for providing pci express connections to ssds for the enterprise market.

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.
Build in sff 8639 connector pin out defined by pcie.
Sff 8639 later renamed to u 2 so you actually remember it is another 2 5 ssd like an sata express ssd except u 2 isn t limited by two lanes up 10gb s performance.
U 2 formerly known as sff 8639 is a computer interface standard for connecting ssds to a computer it covers the physical connector electrical characteristics and communication protocols.
