Purpose and audience

This Vantec UGT-M2670 expansion card adds five SATA III ports through an M.2 PCIe Gen3x2 slot. It suits builders who need extra internal storage connections on a motherboard that offers an NVMe-capable M.2 socket but lacks enough native SATA headers.

Sustained-load behaviour

The JMB585 controller manages the five ports with port-multiplier support and simultaneous command queuing in both AHCI and legacy IDE modes. Backward compatibility with SATA II and I devices is maintained while each port can reach the SATA III 6Gbps theoretical ceiling under continuous transfers.

Thermals noise and power

The compact 80.8 by 25.4 by 10.6 millimetre board draws power directly from the M.2 slot and operates without a fan. LED indicators on each port show drive activity so users can monitor status at a glance while the card runs silently in typical chassis airflow.

Questions about this item

Does the card add any fan noise or need extra power when all five SATA drives run continuously?

The adapter draws power directly from the M.2 slot and has no onboard fan, so it adds no audible noise and requires no auxiliary power cable.

What must the motherboard already provide for this UGT-M2670 to function?

A motherboard with an M.2 NVMe slot that accepts B+M key modules and runs PCIe 3.0 x2; M.2 SATA-only slots are not compatible.

Will my existing SATA II hard drives work at full speed alongside newer SATA III SSDs on this card?

Each port runs at SATA III 6 Gbps and is backward compatible with SATA II and I, so older drives operate at their native rate without limiting newer ones.
