MCIO x8 to Dual U.2 NVMe Adapter

This Vszerda adapter cable expands a single PCIe x8 connection into two U.2 NVMe slots using a SFF-TA-1016 74-pin to dual SFF-8639 68-pin layout. It targets server and workstation builders who need to add high-speed NVMe storage without occupying additional PCIe slots. The 80 cm length suits standard chassis routing.

Sustained PCIe Gen4.0 data transfer

The cable conforms to the PCIe Gen4.0 interface standard, supporting higher sustained data transfer rates and lower latency for demanding storage workloads. Integrated power conductors supply the drives directly, ensuring stable operation during prolonged heavy I/O without relying on motherboard slot power alone. The Mini Cooledge IO construction maintains signal integrity over the full length.

Verify MCIO x8 host port and U.2 drive compatibility

Before ordering, confirm your system provides an MCIO x8 host connector that follows the SFF-TA-1016 pinout and can supply sufficient lane bandwidth. Ensure the target U.2 NVMe drives use the standard SFF-8639 68-pin interface and that physical clearance exists for the 80 cm cable run and drive placement. This adapter does not support SAS drives or M.2 form factors.

Questions about this item

Does the 80 cm MCIO x8 cable add noticeable heat or power draw when two U.2 NVMe drives run continuously?

The adapter is a passive PCIe 4.0 cable assembly; it draws no power itself and adds no active cooling, so heat and power impact come only from the attached U.2 NVMe drives.

What motherboard or backplane connector must I already have to plug in the 74-pin MCIO x8 end?

You need a free MCIO x8 port that follows the SFF-TA-1016 74-pin specification, typically found on modern server or workstation boards supporting PCIe 4.0.

Will the SFF-8639 68-pin U.2 connectors work with older 2.5-inch SAS SSDs I want to keep using?

The cable provides two SFF-8639 68-pin U.2 NVMe interfaces; it does not carry SAS signalling, so legacy SAS SSDs will not operate on these connectors.
