PCIe x16 to 4-Port U.2 NVMe Expansion Card, PCIe 4.0 SFF-8643 Splitter Adapter Compatible with SFF-8639 U.2 SSD, Individual LED Activity Indicators for Server & Workstation

This PCIe x16 to quad U.2 splitter card expands system storage capacity by converting one PCIe x16 slot into four independent SFF-8643 ports, connecting up to four 2.5-inch SFF-8639 U.2 NVMe SSDs for all-flash workstations, storage servers and video editing rigs.

It fully supports PCIe 4.0 bandwidth and maintains full x4 speed per drive under the premise that motherboard BIOS enables PCIe bifurcation (x16 split to 4×x4). Without bifurcation function, only the first U.2 port can be recognized by the system.

Each SFF-8643 port is equipped with an exclusive LED indicator light: steady light for power-on, flickering light for ongoing data read/write, allowing administrators to check drive running status at a glance without entering system software.

Comes with two metal brackets for flexible installation. Full-height bracket fits regular tower cases; low-profile half-height bracket adapts to thin 2U rack servers and mini chassis. High-density multi-layer PCB and impedance-matched signal traces eliminate electromagnetic crosstalk and guarantee stable 24/7 continuous heavy-load operation.

Plug-and-play design requires no additional driver installation. It supports mainstream enterprise U.2 NVMe SSD brands including Intel, Samsung, WD and Micron, and works with all major server & desktop operating systems.
