## Summary description

The StarTech.com 1M25-U3-M2-ADAPTER is an internal M.2 adapter that connects U.3 to M.2. It features a compact design with a width of 70 mm and a height of 7 mm, making it suitable for PC installations. With a mean time between failures of over 12 million hours, it ensures reliability. The adapter outputs 3.3 V at 5 A, providing efficient power for your devices.

## Long description

Connect an M.2 NVMe drive to a 2.5-inch U.3 (SFF-TA-1001) drive bay using the StarTech.com 1M25-U3-M2-ADAPTER. This internal adapter converts PCIe M.2 NVMe/AHCI SSDs in 2242, 2260, or 2280 form factors to a 2.5-inch U.3-compatible module while preserving native PCIe Gen 4 performance. The compact adapter measures 70 mm wide and 7 mm high, supplies 3.3 V at 5 A, and is designed for installation inside PCs and server systems.
Advantages
The adapter changes the M.2 form factor to fit a U.3 drive bay without using an active chipset, maintaining PCIe Gen 4 read and write speeds. It supports backward compatibility with earlier M.2 PCIe NVMe drives and provides a mean time between failures (MTBF) of over 12 million hours. No drivers or additional software are required for operation, and the package includes mounting hardware for both the M.2 drive and the U.3 adapter.
Suitable for
Installing a 2242, 2260, or 2280 M.2 NVMe SSD into a 2.5-inch U.3 drive bay or backplane
Converting internal M.2 PCIe NVMe drives for use in servers or workstations with U.3 bays
Upgrading storage in systems that require a 2.5-inch U.3 form factor while retaining NVMe performance
Key specifications
Compatible M.2 sizes: 2242, 2260, 2280
Interface supported: PCIe M.2 NVMe / AHCI (not compatible with M.2 SATA)
U.3 form factor: SFF-TA-1001 (2.5-inch U.3 bay)
Power output: 3.3 V at 5 A
Dimensions: 70 mm (width) x 7 mm (height)
MTBF: \>12,000,000 hours
Not compatible with SATA or SAS host controllers, M.2 SATA SSDs, or U.2 host interfaces
How to use
Install the M.2 NVMe SSD (2242/2260/2280) onto the adapter using the supplied mounting hardware, secure the drive, and insert the adapter into a 2.5-inch U.3 drive bay or backplane. Ensure the host supports PCIe NVMe over a U.3 interface; no drivers or additional software are required for Windows, macOS, or Linux. Power and data connections are handled through the U.3 bay once the adapter is installed.
Usage recommendations
Use this adapter only with PCIe NVMe M.2 drives (2242/2260/2280). Do not attempt to connect M.2 SATA SSDs or use the adapter with SATA/SAS host controllers or U.2 host interfaces. Verify that the target backplane or host supports U.3 and NVMe before installation to ensure compatibility and preserve full PCIe Gen 4 performance.
