Five-Port SATA Expansion for M.2 Slots

This adapter converts a single M.2 B+M key slot into five SATA 3.0 ports using the JMB575 controller. It targets builders who need extra drive connections on platforms with limited SATA headers. The board requires the host M.2 slot to support the SATA protocol and the motherboard firmware to enable port multiplier mode for all five drives to appear.

Compact Circuit Board with On-Board LED

The PCB uses copper conductors and measures 5.2 by 3.39 by 1.1 inches, weighing 0.02 kilograms. A status LED provides visual confirmation of power and activity. Because the adapter draws power directly from the M.2 slot, no external power cable is needed, but the host must supply enough current for up to five drives.

Passive Cooling and Low Power Draw

The JMB575 integrates five independent SATA channels and a micro-processor in a single chip, eliminating the need for a heatsink or fan. In normal operation the adapter adds negligible heat and noise to the system. Power consumption scales with the number of attached drives, so total draw depends on the specific drives installed.

Questions about this item

Does the JMB575 chip cap the SATA 3.0 link at 6 Gbps?

Yes, the JMB575 provides five independent SATA 6 Gbps channels over the SATA 3.0 interface.

What physical slot does the adapter require on the motherboard?

It needs an M.2 B+M key slot that supports the SATA protocol.

How is the adapter installed and what step is often missed?

Insert the card into the M.2 slot, secure it, connect up to five SATA drives, then enable PM port replication mode in the BIOS so all five drives appear.
