Mini SAS HD SFF8643 to SFF8639 cable

This cable connects a Mini SAS HD SFF8643 host port to SFF8639 U.2 or SAS storage devices. It is built for enterprise server storage expansion, RAID controllers and highcapacity NAS deployments. The integrated SATA 15pin Ytype power branch supplies drive power directly, reducing internal cable clutter. The 39.37inch length fits standard rackmount chassis for flexible routing.

Sustained 12Gbps data throughput

Heavy-duty shielding minimises signal interference during continuous high-bandwidth operation. The construction supports stable 12Gbps SAS transmission across the full cable length without degradation. This reliability suits RAID arrays and NVMe SSD workloads that demand consistent throughput over long periods. The dedicated power branch maintains stable voltage delivery under sustained load.

Check host port and drive connector compatibility

Verify your controller or backplane provides an SFF8643 Mini SAS HD interface before ordering. Confirm the target drives use the SFF8639 U.2 or SAS connector. Ensure the power supply has an available SATA 15pin source for the Ytype branch. This cable does not adapt other port types or provide power conversion.

Questions about this item

Does the 12Gbps link stay reliable when the cable runs all day in a warm server chassis?

The heavy-duty shielding on this 39.37-inch assembly is built to minimise signal interference during continuous operation in dense rack or NAS environments.

My RAID controller only has SFF8643 ports — will the SATA 15-pin Y-type branch plug straight into my existing power supply?

Yes, the integrated 15-pin SATA power fork draws directly from a standard PSU SATA connector, so no extra adapters are required.

Can I attach my older 6Gbps SAS hard drives to the SFF8639 ends without changing drive trays?

The SFF8639 connectors accept both U.2 NVMe SSDs and legacy SAS drives, letting you keep current trays while using the 12Gbps pathway.
