  • Works with standard MKey NVMe slots on motherboards for internal storage upgrades
  • Plug-and-play support for Windows and Linux enables easy multi-drive deployment

M.2 MKey NVMe to 3-Port SATA 3.0 Adapter

This expansion card converts a single M.2 MKey NVMe slot into three independent SATA 3.0 ports using port multiplier technology. It allows builders to connect multiple SATA-based hard drives, SSDs or optical drives inside compact systems. The plug-and-play controller works with Windows and Linux without extra drivers. It targets users adding bulk storage to mini PCs or small NAS units.

Fits Standard M.2 MKey Slots for Internal Expansion

The card installs directly into an available M.2 MKey slot on the motherboard, requiring no external power cables or large drive bays. Its compact M.2 form factor leaves room for other components in tight chassis layouts. It frees up 2.5-inch or 3.5-inch bays by letting SATA drives mount elsewhere in the case. Builders needing more than three SATA connections or RAID features not supported by port multiplication should look elsewhere.

Passive Cooling with Low Power Draw

The controller operates without a fan, relying on motherboard airflow and the card's PCB for heat dissipation. Typical power consumption stays within the M.2 slot's rated delivery, so no auxiliary connectors are needed. Silent operation suits noise-sensitive environments like living-room NAS builds. Heavy sustained multi-drive workloads may warm the PCB, so ensure the slot area receives adequate case ventilation.

Questions about this item

Will the single 6Gbps SATA 3.0 link saturate when three drives are active at once?

Yes, the three ports share one 6Gbps SATA 3.0 connection through the port multiplier, so combined throughput cannot exceed that bandwidth.

Does the card need extra power or cooling when running three drives continuously?

It draws power from the M.2 slot and has no onboard fan or heatsink; sustained loads rely on case airflow alone.

What motherboard slot is required for this adapter to function?

An M.2 M-key slot wired for NVMe is required; the card will not work in B-key, M-key SATA-only or PCIe slots.
