Convert and connect a PCIe M.2 NVMe/AHCI SSD to a 2.5inch form factor to install in a U.3 drive bay or backplane.

Adapt While Retaining Performance

Change the form factor of a 2242, 2260, or 2280 M.2 NVMe drive while maintaining PCIe Gen 4 read and write speeds. This adapter has been designed with no chipset to maintain performance when adapting an M.2 drive to a 2.5-inch form factor.

Hassle-Free Setup

The M.2 to U.3 Host Adapter is compatible with all operating systems, including Windows, macOS, and Linux. No additional drivers or software for installation and operation. The adapter includes M.2 drive and U.3 adapter mounting hardware.

Compatibility

The M.2 to U.3 Host Adapter is backward compatible with earlier versions of M.2 PCIe NVMe drives. It is not compatible with SATA or SAS host controllers, M.2 SATA SSDs, or U.2 host interfaces.

Applications

  • Connect an M.2 NVMe SSD to a computer or server through an available U.3 (SFF-TA-1001) connection to increase data storage capacity
  • Enhance productivity for data-intensive applications, making it ideal for developers and content creators
