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.

Questions about this item
Does the PH49 card need active cooling for 24/7 operation?
The card has no onboard fan; it relies on chassis airflow to keep the PCIe 4.0 x16 link and four U.2 ports stable during continuous use.
What bandwidth ceiling appears first when all four U.2 NVMe drives run sustained workloads?
The single PCIe 4.0 x16 upstream link caps aggregate throughput at 16 GT/s, so simultaneous heavy I/O on all four ports shares that ceiling.
How loud is the PH49 when drives are active all day?
The card itself is silent — no moving parts — so any noise comes only from the U.2 NVMe drives and the system fans cooling them.
