SMUGDESK

SMUGDESK 12Gbps Mini SAS HD SFF8643 to U.2 SFF8639 Cable 0.5m

SKU CH-PD28-4T42D

Connects a Mini SAS HD SFF8643 port to a U.2 SFF8639 NVMe SSD at 12Gbps with .5m shielded cabling for dense server builds

  • Direct SFF8643-to-SFF8639 link enables NVMe U.2 SSD deployment
  • 12Gbps bandwidth supports enterprise-grade storage performance
  • .5m length keeps internal server wiring clean and tidy
  • Server-grade shielding reduces signal loss, crosstalk and EMI
  • Designed for RAID controllers, storage arrays and data center U.2 expansion

Direct NVMe U.2 Connectivity

This cable links a Mini SAS HD SFF8643 port to a U.2 SFF8639 drive bay, enabling direct NVMe SSD deployment. It targets system builders and administrators expanding high-speed storage in enterprise servers or RAID arrays. The 12Gbps rated bandwidth supports demanding data-center workloads without protocol conversion.

Route Internal Wiring

The .5 metre length is designed for tight chassis routing between adjacent backplanes and controllers. It eliminates excess cable bulk that can obstruct airflow in dense 1U or 2U systems. Builders gain a clean signal path without reserving space for long cable management loops.

Shielded Signal Integrity

Server-grade shielding suppresses crosstalk and electromagnetic interference across the link. This preserves the 12Gbps throughput during sustained read and write operations. The passive assembly draws no additional power and adds no active cooling requirement to the thermal budget.

Questions about this item

Does the 0.5 m length limit the distance between my RAID controller and the U.2 backplane?

The 0.5 m cable is designed for short internal routing inside a compact server chassis; ensure the SFF8643 port and SFF8639 drive bay are within that reach.

Will the shielding keep noise and heat in check during continuous 12Gbps transfers?

Server-grade shielding minimises signal loss, crosstalk and electromagnetic interference, so the link stays stable under sustained enterprise workloads.

My controller only has SFF8643 ports — can I plug this straight in?

Yes, the cable provides a direct SFF8643 Mini SAS HD to SFF8639 U.2 connection for NVMe U.2 SSD deployment.
