SMUGDESK M.2 A+E Key to 2-Port SATA 3.0 Riser Card JMB582 Chip M.2 WiFi Slot to SATA Adapter

SKU CH-MTZ9-1XE9V

Converts an M.2 A+E Key WiFi slot into two SATA 3.0 ports using a JMB582 chip for 2.5 and 3.5 inch drives

  • Adds two SATA 3.0 ports via M.2 A+E Key slot
  • JMB582 chip delivers steady 6Gbps transfer speed
  • Works with 2.5 and 3.5 SATA HDD and SSD
  • Compact design fits mini PC, NAS and small chassis
  • Plug and play with no extra drivers required

M.2 A+E Key to dual SATA 3.0 riser

This adapter converts an M.2 A+E Key WiFi slot into two independent SATA 3.0 ports running at 6Gbps. It uses the JMB582 controller chip to maintain stable data transmission for added storage. The card supports both 2.5 and 3.5 inch SATA hard drives and solid-state drives. Installation is plug-and-play with no extra drivers required on mainstream operating systems.

Suits compact systems needing extra SATA ports

Builders with mini PCs, NAS units or small chassis can add two drives through the existing WiFi slot. Hot-swap support allows drive changes without powering down the system. It does not help systems that lack an M.2 A+E Key slot or builders who need more than two drive connections.

JMB582 chip enables 6Gbps SATA

The JMB582 controller provides the 6Gbps transfer rate across both ports. This chip determines the maximum throughput available to attached drives. Verify that the host platform exposes the M.2 A+E Key interface before purchase.

Questions about this item

Which devices can I connect to the two SATA ports?

You can attach both 2.5 and 3.5 SATA hard drives or SSDs to the two independent SATA 3.0 ports provided by the JMB582 chip.

What throughput will I actually see on each SATA port?

Each port runs at SATA 3.0 6Gbps, so the practical ceiling is the SATA 3.0 bus limit rather than the M.2 A+E Key slot itself.

Does the M.2 A+E Key interface restrict the SATA speed in any way?

The adapter converts the M.2 A+E Key WiFi slot into two full SATA 3.0 6Gbps channels, so the SATA bus runs at its native rate without extra driver overhead.
