PCIe 3.0 x4/x16 U.2 Adapter Card

This PCIE 3.0 x4/x16 adapter card connects U.2 SFF8639 NVMe SSDs, M.2 NGFF drives and 2.5inch U.2 solid-state drives to a desktop, workstation or server. It uses the NVMe protocol for high-speed data transmission and fits a standard PCIE X16 bracket for straightforward installation.

Suits builders adding enterprise U.2 storage

The card serves users who want to install U.2 NVMe SSDs in systems with a free PCIE 3.0 x4 or x16 slot, including NAS appliances and high-capacity workstations. It is not for buyers who need to connect drives using a different interface or protocol than NVMe, or who lack a compatible PCIE expansion slot.

PCIe 3.0 x4/x16 interface decides fit

The adapter operates on a PCIE 3.0 x4 or x16 link, so the host slot must provide that electrical width and generation for the U.2 NVMe SSD to function at its rated speed. Verify the motherboard or riser supplies a PCIE 3.0 x4 or x16 connection before purchase.

Questions about this item

Does the SMUGDESK PCIe 3.0 x4/x16 to U.2 SFF8639 adapter include cables, or must they be purchased separately?

The adapter card uses a standard PCIe x16 bracket and connects directly to the slot; no cables are required for the PCIe link, while the U.2 SFF8639 drive attaches natively to the onboard connector.

Should I choose the x4 or x16 slot version for my U.2 NVMe SSD?

Both x4 and x16 slots accept the card; the adapter runs at PCIe 3.0 x4 electrically, so a physical x16 slot works fine and an x4 slot provides the same NVMe bandwidth.

What does PCIe 3.0 x4 mean for real-world U.2 NVMe SSD speed in my desktop?

The interface provides four lanes of third-generation PCIe, giving the U.2 NVMe SSD its full rated throughput for fast boot, large file transfer and heavy workload acceleration.
