Add a 2.5 inch U.3 NVMe SSD into a PCIe 4.0 x4/x8/x16 slot in a desktop or server using the included screws, enabling ultra-fast data access.

Add U.3 Capabilities to a Desktop or Server

Install an SFF-TA-1001 SSD into a desktop or server using an available PCI Express 4.0 slot. The pre-installed full-profile bracket and included drive mounting screws enable the connection of a U.3 NVMe drive to a PCIe slot, avoiding the need for a drive backplane or additional cables. This adapter is not compatible with U.2 drives.

Universal Compatibility

The Adapter Card is backward compatible with motherboards that feature x4, x8, and/or x16 PCIe 3.0 slots. The U.3 Adapter requires no additional drivers or software and works with all workstation and server operating systems, such as Windows, Windows Server, and Linux.

Optimal Airflow and Reliable Performance

The vented full-profile bracket and a large cutout in the PCB allow for better airflow and heat dissipation, which helps maintain optimal and reliable performance while avoiding thermal throttling.
