ADT-LINK M.2 NVMe SSD to PCI Express 4.0 X4 Extension Cable Full Speed 64G/BPS Solid State Drive Riser Card Support SSD 2230 2240 2260 2280 22110 (30CM,R44SF 4.0)

Differential signal without hole design, there is no problem of signal attenuation interference in a parasitic capacitance and parasitic inductance, there will be no more CAF micro short circuit, cable is durability.
PCB use high frequency low resistance of materials with high quality, PCB using high TG board, copper thickness thicken to 1oz, gold finger plating enough gold, Good conductive performance, can reduce oxidize higher impedance caused by the crash blue screen.
Connector 1:  M.2 NVMe SSD ;Connector 2: PCI-E 4X
Only supports one gap M-key NVMe SSD, Don't support two gaps BM-key SATA SSD .
Note: R44SF 4.0 supports PCIe4.0, but the signal will be attenuated as long as the extension cable is connected. This product does not guarantee PCIE4.0 full speed, equipment aging, poor signal or poor environment, please reduce the speed to use.
