U.2 SFF-8639 to PCIe 3.0 X4 Adapter

This adapter card connects a 2.5" U.2 NVMe or SATA SSD to a desktop, server or workstation through a PCIe 3.0 X4 slot. It delivers up to 32Gbps bandwidth so the drive can run at its rated speed. The card fits X4, X8 or X16 slots and works with PCIe 2.0 and 1.0 systems. No extra drivers are required for installation.

Suits builds adding enterprise U.2 storage

Builders who want to install a 2.5" U.2 NVMe or SATA SSD in a standard PCIe slot will find this card fits the purpose. It supports drives from mainstream brands such as Intel, Samsung and Micron. Systems without a free PCIe slot or users who need M.2 or SATA cabling instead should look at a different solution.

PCIe 3.0 X4 interface for full U.2 performance

The card provides a native PCIe 3.0 X4 link to the U.2 drive, preserving the 32Gbps throughput the SSD is designed for. Backward compatibility with PCIe 2.0 and 1.0 allows it to function in older platforms, though at reduced bandwidth. This single interface specification determines whether the adapter matches the host system and drive.

Questions about this item

Does the box include a 2.5" U.2 NVMe or SATA SSD, or must I buy the drive separately?

The adapter card is sold by itself; a 2.5" U.2 NVMe or SATA SSD must be purchased separately.

The card supports PCIe 3.0 X4, 2.0 and 1.0 — which slot version should I use for full 32Gbps bandwidth?

Install it in a PCIe 3.0 X4, X8 or X16 slot to reach the full 32Gbps bandwidth; older 2.0 or 1.0 slots will run at lower speeds.

What does the 32Gbps figure mean when the card is running in a real desktop or server?

It is the peak PCIe 3.0 X4 interface bandwidth available to the U.2 NVMe or SATA SSD; actual transfer rates depend on the specific drive and system workload.
