Target Build

This Vszerda cable connects a single MCIO x8 host port to two SFF-8639 U.2 NVMe SSDs. It is built for workstations or servers that need to add high-speed flash storage without occupying standard drive bays. The 50 cm length suits typical chassis routing. Buyers who need more than two U.2 devices or a different host connector should look elsewhere.

Sustained Behaviour

The link runs at PCIe 4.0 x8, providing 128 gigabits per second of total bandwidth shared across both drives. Backward compatibility with PCIe 3.0 allows the same cable to function in older platforms at reduced throughput. Each SFF-8639 connector uses 68 pins to carry data and side-band signals for dual SSD operation.

Thermals Noise Power

Passive copper conductors add no active cooling requirement and generate no acoustic noise. A 15-pin SATA power tail supplies the U.2 drives directly from the system PSU, so no extra power adapter is needed. The cable complies with SCSI SAS and PCIe Gen4 electrical specifications for reliable enterprise deployment.

Questions about this item

Does the 16 GT/s PCIe 4.0 link generate extra heat or power draw during all-day use?

The cable itself is passive copper and adds no active heat or power; the 128 gigabits_per_second signal is carried by the host and the two U.2 NVMe SSDs.

What connector must already exist on my motherboard or controller for this MCIO x8 cable to plug in?

A 74-pin SFF-TA-1016 MCIO x8 receptacle is required on the host side.

Will the dual SFF-8639 ports work with PCIe 3.0 U.2 drives I already own?

Yes, the cable is backward compatible with PCI-Express 3.0, so older U.2 NVMe SSDs will operate at their rated Gen 3 speeds.
