SMUGDESK M.2 B+M Key / M-Key to 5/6 Port SATA 3.0 Expansion Card

SKU CH-A6KQ-E26MG

Converts an M.2 slot into five or six SATA 3.0 ports at 6Gbps for HDD and SSD expansion

  • Converts M.2 B+M Key / M-Key to multiple SATA 3.0 ports for storage expansion
  • Provides 5 or 6 SATA ports with 6Gbps bandwidth for fast data transfer
  • Compatible with NVMe and standard NGFF M.2 SSDs for broad system support
  • Professional controller chip maintains stable signal for reliable long-term operation
  • Compact riser design enables simple plug-and-play installation in desktops and small chassis

M.2 to SATA 3.0 expansion card

This M.2 B+M Key and M-Key adapter converts a single NGFF slot into five or six independent SATA 3.0 ports. It accepts both NVMe and standard M.2 SSDs for broad host compatibility. The compact riser design fits desktops and small chassis with simple plug-and-play installation.

Five or six ports at 6Gbps each

Each SATA port delivers 6Gbps bandwidth to handle daily workloads and mass storage arrays of HDDs and SSDs. The professional controller chip maintains stable signal integrity across all connected drives. Total throughput is shared across the upstream M.2 link, so simultaneous heavy traffic on every port will saturate the host interface.

M.2 B+M Key and M-Key host requirement

The card only functions when installed in an M.2 slot wired for B+M Key or M-Key signalling. Systems lacking a compatible M.2 NGFF interface cannot use this adapter. Buyers needing to add SATA ports via PCIe, USB or legacy headers must choose a different expansion method.

Questions about this item

Will this card fit in my motherboard's M.2 B+M Key slot alongside my existing NVMe drive?

The card plugs into an M.2 B+M Key or M-Key slot and provides 5 or 6 SATA 3.0 ports; it does not pass the original NVMe signal through, so the slot is used solely for SATA expansion.

How do I verify each of the 6Gbps SATA ports is active after installation?

Connect a SATA drive to each port, enter BIOS or OS disk management, and confirm every drive appears at SATA 3.0 6Gbps link speed.

Does the box include SATA data cables for the 5 or 6 ports, or must I buy them separately?

The card itself is supplied; SATA data cables and drive power cables are not included and must be purchased separately.
