Short .5m cable with SFF8643 and SFF8639 connectors, black shielding

SMUGDESK

SMUGDESK 12Gbps SFF8643 to SFF8639 SAS Cable .5m

SKU CH-8S84-BK4PG

Connects SFF8643 Mini SAS HD to SFF8639 U.2 for 12Gbps NVMe SSD links in tight server builds

  • Direct NVMe U.2 SSD connection via SFF8643 to SFF8639
  • 12Gbps bandwidth for enterprise storage performance
  • .5m length allows clean routing in compact chassis
  • Server-grade shielding reduces signal loss and crosstalk
  • Designed for RAID controllers and data center expansion

Direct SFF8643 to SFF8639 connection

This cable links a Mini SAS HD port to a U.2 interface for NVMe SSD deployment. It supports 12Gbps bandwidth for enterprise storage performance. The .5m length suits compact server chassis and storage arrays.

Simple internal routing

The short .5m design allows clean cable management inside dense enclosures. Servergrade shielding reduces signal loss and crosstalk during installation. Ensure the SFF8643 and SFF8639 connectors align correctly with your controller and drive ports.

Verify port compatibility

Confirm your RAID controller or backplane provides an SFF8643 Mini SAS HD output. Check that the target U.2 SSD uses an SFF8639 interface for direct attachment. This cable does not adapt to other form factors or interface types.

Questions about this item

How can I verify the 12Gbps link is active after connecting the SFF8643 to SFF8639 cable?

Check the RAID controller or HBA management utility for a negotiated 12Gbps link speed on the U.2 port and run a NVMe drive benchmark to confirm throughput.

What comes with the SMUGDESK cable and what must I supply separately?

The package includes the .5m SFF8643 to SFF8639 cable only; you must provide the NVMe U.2 SSD, a compatible SAS controller or backplane with SFF8643 ports, and any drive mounting hardware.

Which version should I choose for a .5m internal NVMe U.2 SSD link?

Select this .5m SFF8643 to SFF8639 model when the controller uses Mini SAS HD ports and the drive uses a U.2 connector, keeping the short run inside a compact server chassis.
