SMUGDESK PH49 PCIe 4.0 x16 to 4-Port U.2 NVMe Expansion Card SFF-8643/SFF-8639 PCIe Split Half Height

Four U.2 ports from one x16 slot

The SMUGDESK PH49 converts a single PCIe 4.0 x16 slot into four U.2 NVMe connectors using SFF-8643 and SFF-8639 interfaces. It targets system builders who need dense, high-speed storage in workstations or rack servers without occupying multiple expansion slots.

PCIe split and half-height form factor

The card splits the x16 link so it also functions in x4 and x8 slots, letting the same adapter serve different chassis layouts. Its half-height bracket fits slim enclosures where a full-height card would not clear the lid or adjacent modules.

Runs four NVMe drives at 4.0 speeds

Each port delivers a full PCIe 4.0 lane group to the attached SSD, so four drives operate at their rated throughput simultaneously. Builders needing more than four U.2 devices or a x16 slot for a GPU will need a different expansion approach.
