Flat 80 cm cable with SFF8654 38 pin and SFF8643 36 pin connectors

SMUGDESK

SMUGDESK SlimSAS SFF8654 to MiniSAS HD SFF8643 80cm

SKU CH-W0R3-5704F

Connects SFF8654 SlimSAS to SFF8643 MiniSAS HD for PCIe Gen4.0 and SAS3.0 server storage

  • Bidirectional link joins SFF8654 38pin SlimSAS 4X and SFF8643 36pin MiniSAS HD
  • PCIe Gen4.0 and SAS3.0 support delivers highbandwidth data transfer
  • 80cm length allows flexible routing inside rackmount servers and storage enclosures
  • Precisionmatched impedance wiring reduces signal loss and crosstalk for stable performance
  • Shielded harness suits RAID controllers, NVMe SSDs and highcapacity storage arrays

Cable type and target build

The SMUGDESK cable links a 38pin SFF8654 SlimSAS 4X port to a 36pin SFF8643 MiniSAS HD connector. It serves administrators and integrators connecting PCIe Gen4.0 or SAS3.0 storage devices inside enterprise servers and rackmount enclosures.

Build integration and routing

The 80cm length allows tidy internal runs between backplanes, RAID controllers and NVMe SSD trays without excess slack. Shielded construction keeps the signal clean in dense chassis, freeing adjacent bays for additional drives or airflow.

Thermals noise and power

Passive copper wiring adds no fan noise and draws no auxiliary power. Impedancematched conductors limit loss at full protocol speed, so the link stays stable under sustained enterprise workloads without generating extra heat.

Questions about this item

At what bandwidth does the SlimSAS SFF8654 38pin interface cap sustained transfers?

The cable is built to PCIe Gen4.0 and SAS3.0 specifications, so the link speed is limited by the host controller and drive capabilities at those protocol levels.

How does the 80cm shielded harness behave for heat and noise during all-day operation?

Passive copper construction produces no noise and negligible heat; the server-grade shielding maintains signal integrity without active cooling.

Which controller or backplane ports must the system already provide for this cable to function?

One end requires an SFF8654 38pin SlimSAS 4X port and the other an SFF8643 36pin MiniSAS HD port on the host or storage enclosure.
