Integrated high-speed signal enhancement technology, full-speed transmission, precise, and solid structural design.Support of dual interface protocol: U.2 SDD (direct use without connection) / SATA SDD (required to connect the SATA data cable).The U.2 interface supports the NVMe standard protocol, high speed, low latency and low power consumption, bandwidth takes PCI-E3.0 x4, transmission speed up to 32 Gbit / s, 5 A power supply module (SATA only 6 Gbit / s , more than five times faster than SATA).PCIE3.0 x4 GEN3 design, full speed from the bottom of the technology.The U.2 interface uses two SATA 6 Gbit / s interfaces and a 4-pin mini SATA interface. The small interface can only be connected to the PCI-E cable to backward compatibility.Colour: blackMaterial: PCB+metalSize: 140x120mmPackage Contents:1 * U.2 TO PCIE X4 Riser Card1 * SATA3.0 Cable (the color of the cable is random, don't accept the specified color)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
