4 Port M.2 to SATA 3.0 Expansion Card

This card converts a single M.2 slot into four independent SATA 3.0 ports running at 6Gbps. It includes four SATA cables so drives can be connected immediately. The design targets desktop users who want to add multiple hard drives or SSDs through one expansion slot.

Suits builders adding several SATA drives

The adapter works with Windows 10 and Windows 11 and fits compact cases where space is limited. It is not suited for systems that lack a compatible M.2 slot or for users who need to connect drives using a different interface.

Requires a motherboard M.2 slot that supports SATA

The card only functions when the M.2 socket carries SATA lanes; it will not operate in slots wired exclusively for PCIe storage. Verify the motherboard manual before purchase to ensure the slot provides the necessary SATA pathways.

Questions about this item

Does the 6 Gbps SATA 3.0 link become a bottleneck when all four ports are saturated?

Each port runs at the full SATA 3.0 6 Gbps rate, so the limit is the standard interface speed rather than the card itself.

How much heat does the controller produce during continuous operation?

The compact board uses a low-power controller that stays cool under normal desktop loads without active cooling.

What M.2 slot keying and length does the host motherboard need to provide?

The card fits a standard M.2 M-key slot; the motherboard must supply an M.2 interface that supports SATA signalling.
