PCIe 4.0 x16 to 4-Port U.2 NVMe Expansion Split Card, SFF-8643 SFF-8639 U.2 Adapter Card with Independent LED Activity Indicators for Desktop PC & Server

This PCIe x16 to 4-port U.2 NVMe split expansion card adopts PCIe 4.0 high-speed transmission standard, which divides one PCIe x16 channel into four independent PCIe x4 channels. It is connected to U.2 NVMe SSDs via SFF-8643 MiniSAS cables, perfectly compatible with SFF-8639 U.2 solid state drives, and each SSD can run at full native bandwidth without speed bottlenecks.

Equipped with independent LED activity lights for every port, users can quickly check power supply and data transmission status of each hard drive at a glance, convenient for daily maintenance and fault troubleshooting. The card supports PCIe bifurcation function (motherboard BIOS needs to enable x4x4x4x4 split mode), and is backward compatible with PCIe 3.0 mainboards, widely applied to video workstations, storage servers, high-end gaming desktops and DIY storage expansion hosts.

Made of thickened gold-plated golden fingers and industrial-grade PCB board, it effectively reduces signal attenuation and electromagnetic interference during long-time high-load operation. The card supports mainstream Windows and Linux operating systems, and works well for 4K/8K video rendering, mass file storage, server data caching and professional content creation storage expansion.
