SMUGDESK

SMUGDESK SFF8639 U.2 NVMe to M.2 MKey SATA PCIe SSD Adapter

SKU CH-62RV-HRZ3X

Converts SFF8639 U.2 NVMe to M.2 MKey for Intel 750, P3600, P3700 SSDs with dual PCIe NVMe and SATA support

  • Converts U.2 NVMe to M.2 MKey for flexible SSD use
  • Supports both PCIe NVMe and SATA M.2 drives for multiprotocol compatibility
  • Compatible with Intel enterprise SSDs 750, P3600, P3700 series
  • Enables motherboard SSD replacement and enterprise storage expansion
  • Compact plugandplay design with stable signal transmission for servers

U.2 to M.2 Adapter for Enterprise SSDs

This SMUGDESK adapter converts an SFF-8639 U.2 NVMe port to an M.2 MKey interface. It enables the use of Intel enterprise SSDs including the 750, P3600 and P3700 series on motherboards equipped with M.2 slots. The compact design provides plug-and-play installation for server and workstation storage upgrades.

Suits Builders Using Intel U.2 Drives

It suits administrators and enthusiasts who need to install Intel 750, P3600 or P3700 drives into standard M.2 MKey sockets. The adapter handles both PCIe NVMe and SATA protocols for multiprotocol compatibility. Builders requiring a U.3 interface, OCuLink connectivity or support for E1.S form factors should look at other solutions.

Protocol Flexibility Changes Drive Choice

The bundled circuitry allows a single M.2 slot to accept either PCIe NVMe or SATA MKey SSDs without configuration. This means an Intel P3700 NVMe drive and a SATA M.2 drive can both connect through the same adapter. No software, drivers or additional power cables are included or required for operation.

Questions about this item

My motherboard only has M.2 MKey slots — what else do I need to connect an Intel SSD 750, P3600 or P3700 through this adapter?

You need an SFF8639 U.2 NVMe drive and an M.2 MKey slot that accepts both PCIe NVMe and SATA signals. The adapter itself is passive and requires no extra power or cables.

Will this adapter let me keep using my older SATA M.2 drive alongside a new NVMe U.2 drive?

Yes, the M.2 MKey connector on the adapter supports both PCIe NVMe and SATA protocols, so you can swap between NVMe U.2 drives and legacy SATA M.2 drives without changing hardware.

How can I confirm the adapter is passing data correctly after I install an Intel P3600?

The drive should appear in BIOS and the OS at full PCIe NVMe speed. Run a quick read/write test — stable throughput and no disconnects mean the signal path through the SFF8639 U.2 to M.2 MKey conversion is working.
