PCIe 4.0 SlimSAS 8i to dual U.2 cable

This 0.7m cable connects a single SFF-8654 port to two SFF-8639 U.2 drive bays. It suits builders adding high-speed storage to servers or workstations with limited backplane ports. The assembly carries PCIe 4.0 signals at 24Gb/s per lane.

Passive copper construction for cool operation

The cable uses passive copper wiring that draws no power and adds no active heat to the chassis. No fan or controller is required, so acoustic output stays at zero decibels. Signal integrity is maintained across the 70cm run without external cooling.

SlimSAS 8i plug frees internal routing space

The narrow SFF-8654 connector occupies less PCB edge room than legacy mini-SAS HD plugs. Two SFF-8639 tails route directly to U.2 drive cages or backplanes. This layout leaves adjacent motherboard slots and airflow paths unobstructed.

Questions about this item

How do I connect the SFF-8654 SlimSAS 8i end to a PCIe 4.0 host adapter and avoid reversing the two SFF-8639 U.2 branches?

Align the keyed SFF-8654 connector with the host port, push until the latch clicks, then route each SFF-8639 branch to its matching U.2 backplane bay; the Y-split is fixed so the cable only fits one way.

What upkeep will the 0.7 m Luxshare cable need over time?

Inspect the latch tabs and connector gold fingers every few months for dust or bent pins; reseat both SFF-8639 ends if intermittent link errors appear.

At 24 Gb/s throughput, what limit appears first during sustained transfers?

The 70 cm length and PCIe 4.0 electrical budget cap the signal budget, so latency and eye-diagram margin become the bottleneck before the copper itself saturates.
