Converts an M.2 A+E WiFi slot into two independent SATA 3.0 ports using a JMB582 chip for compact storage expansion

  • Converts an unused M.2 WiFi slot into two SATA 3.0 ports using the JMB582 controller
  • Adds 2.5 and 3.5 SATA storage without occupying a PCIE slot
  • Compact low-profile design fits tight miniPC and NAS chassis
  • Plug-and-play operation on Windows and Linux for simple upgrades
  • Provides two independent 6Gbps SATA connections for HDDs and SSDs

M.2 A+E Key to Dual SATA 3.0 Adapter

This SMUGDESK expansion card converts an unused M.2 A+E Key WiFi slot into two independent SATA 3.0 6Gbps ports using a JMB582 controller. It enables storage upgrades in miniPCs, NAS units and compact servers without consuming a PCIe slot. The low-profile design suits tight chassis and simplifies internal cabling. Plug-and-play operation works with Windows and Linux systems.

Suits builders adding SATA drives to a spare WiFi

Ideal for users with an available M.2 A+E Key interface who want to connect 2.5" or 3.5" SATA hard drives or SSDs. It fits small-form-factor builds where PCIe slots are occupied or absent. Builders whose motherboards lack an M.2 A+E Key slot cannot use this adapter. Users needing more than two SATA connections will require a different solution.

JMB582 chipset drives two SATA 3.0 ports

The JMB582 controller provides the bridge between the M.2 A+E Key interface and the dual SATA 3.0 connectors. It delivers 6Gbps bandwidth per port for compatible drives. This chipset determines compatibility with the host slot and the maximum number of supported drives. Verify your motherboard exposes an M.2 A+E Key slot before purchase.

Questions about this item

How can I confirm the JMB582 card is working after installing it in the M.2 A+E key slot?

After installation, check your BIOS or operating system disk management utility to verify both SATA 3.0 ports are detected and any connected 2.5 or 3.5 drives appear with correct capacity.

What is included with the SMUGDESK expansion card and what must I purchase separately?

The card itself is supplied; you will need to buy SATA data cables, power cables or adapters, and the 2.5 or 3.5 SATA HDDs or SSDs you intend to use.

Which version of this adapter should I choose for a mini PC with a spare M.2 WiFi slot?

This single JMB582-based model converts one M.2 A+E key slot into two SATA 3.0 ports, matching the described use case for compact builds.
