M.2 NVMe to U.2 Adapter

The StarTech U2M2E125 adapter lets you install a single M.2 PCIe NVMe SSD with an M-Key connector into a desktop PC or server that provides a U.2 (SFF-8639) host interface. It measures 100 mm long, 70 mm wide and 7 mm high, weighing 36 g. No drivers or software are required for installation.

For U.2-equipped builds; not for M.2-only boards

This card suits builders and IT professionals adding NVMe storage to systems with a free U.2 port or compatible drive bay. It will not work on motherboards that lack a U.2 (SFF-8639) interface or on platforms that only offer M.2 slots for direct SSD attachment.

U.2 (SFF-8639) host interface required

The adapter connects one M.2 NVMe SSD (M-Key, PCIe x4) to a single U.2 (SFF-8639) host connector running four PCIe lanes. If your board or backplane does not expose a U.2 port, this adapter cannot be used.

Questions about this item

Does the U2M2E125 include an M.2 NVMe SSD, or do I need to buy the drive separately?

The adapter supports one M.2 PCIe NVMe SSD (M-Key); the drive itself is not included and must be purchased separately.

How do I know if my M.2 SSD is the right M-Key type for this U.2 adapter?

Check the SSD edge connector — an M-Key module has a single notch on the right side and is labelled PCIe x4 NVMe; only that keying fits the adapter slot.

What real-world speed can I expect when the adapter links an NVMe drive to a U.2 (SFF-8639) motherboard port?

The adapter passes through a full PCIe x4 NVMe connection, so the drive runs at its rated NVMe speeds, limited only by the drive and the host U.2 controller.
