M.2 2242 SATA expansion

This adapter plugs into an M.2 2242 B+M key slot and provides two SATA 3.0 ports for connecting hard drives or SSDs. It uses the JMicron JMB582 chipset and requires no driver installation on Windows, macOS or Linux.

Capacity and headroom

Each port supports the SATA 3.0 transfer rate up to 6 Gbps with a maximum sequential read or write speed of 850 MB/s. Two drives can operate simultaneously using FIS-based and command-based port multiplier switching. Hot-plug and hot-swap are supported on both ports.

SATA 3.0 interface limits

The SATA 3.0 standard caps throughput at 6 Gbps so faster SSDs will not exceed that ceiling. Total bandwidth is shared across the two ports when both are active. The card fits only M.2 2242 slots and cannot be used with longer M.2 modules.

Questions about this item

Will this SI-ADA40149 card work in a laptop that only has an M.2 2242 slot available?

Yes, the card uses an M.2 2242 B+M key form factor, so it fits directly into that slot and adds two SATA 3.0 ports.

How can I confirm the JMB582 controller is running at full 6 Gbps speed after installation?

Check the OS device manager or dmesg logs for a SATA 3.0 link negotiation; the card supports up to 6 Gbps per port with a maximum sequential throughput of 850 MB/s.

Does the package include the SATA data cables for the two drives, or must I buy them separately?

Only the controller card is supplied; you will need to provide two standard SATA data cables to connect your drives.
