SMUGDESK M.2 B-Key SATA 3.0 to 2.5" SATA Adapter

SKU CH-KGVW-M5RK8

Converts a B-Key M.2 SATA SSD to a 2.5-inch SATA 3.0 interface for laptop or desktop upgrades

  • Converts B-Key SATA M.2 SSDs to 2.5 SATA for bay installation
  • SATA 3.0 6Gbps bandwidth delivers full SSD read and write performance
  • Compact PCB with screws and standoffs fits tight chassis spaces
  • Plug-and-play operation requires no extra drivers on mainstream OSes
  • Stable bridge chip ensures reliable data transfer with low power draw

M.2 B-Key SATA to 2.5-Inch Adapter

This adapter converts a B-Key M.2 SATA solid-state drive into a standard 2.5-inch SATA form factor. It allows installation of M.2 SATA SSDs into traditional drive bays, external enclosures, or older systems lacking M.2 slots. The board uses a high-stability bridge chip for reliable data transmission. It is designed for users upgrading laptops or desktops with existing M.2 SATA drives.

SATA 3.0 6Gbps Interface Limit

The adapter operates strictly under the SATA 3.0 standard with a maximum bandwidth of 6Gbps. It does not support NVMe protocol drives, including M-Key or B+M Key NVMe SSDs. Performance is bounded by the SATA interface speed of the connected M.2 SSD and the host controller. No driver installation is required for mainstream operating systems.

Verify SSD Protocol and Key Before Ordering

Confirm your M.2 SSD uses the B-Key physical connector and SATA protocol before purchasing. This adapter will not recognise or function with NVMe protocol drives. Check that your target system has an available 2.5-inch SATA port and power connection. The package includes fixing screws and copper standoffs for secure mounting inside a chassis.

Questions about this item

Which M.2 SSD should I choose for this 2.5 SATA adapter?

Select a B-Key M.2 NGFF drive that uses the SATA protocol; M-Key or B+M-Key NVMe modules will not work with this board.

What does the 6Gbps SATA 3.0 rating deliver in a real system?

It lets a SATA M.2 SSD run at its native 6Gbps ceiling, so boot times, app launches and large-file copies match the drive's rated performance.

How does the SATA 3.0 interface limit the adapter in practice?

The board passes SATA 3.0 signals directly to a 2.5 SATA port, so throughput is capped at 6Gbps and NVMe drives cannot be used at all.
