SMUGDESK Internal HD Mini SAS Breakout Cable SFF8643 to 4×SFF8482 29Pin 12Gbps SAS3.0

SKU CH-T1BA-D51YY

Connects a RAID controller to four SAS or SATA drives using a MiniSAS HD SFF8643 host port and SFF8482 29Pin breakout connectors at 12Gbps

  • Splits one SFF8643 port into four 29pin SFF8482 drives
  • Delivers 12Gbps SAS3.0 bandwidth per drive port
  • Shielded wiring keeps signals clean during 24hour server runs
  • Latching connectors lock tight against chassis vibration
  • Connects RAID HBA to SAS SATA HDD SSD arrays

Forward breakout cable for RAID controllers

This internal HD Mini SAS cable uses an SFF8643 host connector to split into four SFF8482 29pin target ports. It connects a RAID controller or HBA card directly to SAS and SATA hard drives or SSDs inside a server chassis. The forward breakout design is built for enterprise storage expansion in NAS, JBOD and RAID array deployments. Buyers needing a reverse-direction backplane-to-controller cable cannot use this product.

Shielded wiring and latching connectors

Multilayer shielding reduces signal interference during continuous 24hour operation at up to 12Gbps per-port bandwidth under the SAS 3.0 standard. Firm latching connectors lock securely to prevent loose contact caused by cabinet vibration. The cable supports stable high-throughput reading and writing across all four connected drives. No additional software or drivers are included; the cable is purely a physical interconnect.

Internal chassis installation only

Installation requires routing the cable inside a server chassis between the controller card and drive bays, confirming the host card supports SFF8643 forward breakout function beforehand. The rigid shielding and latch mechanism demand adequate clearance for connector engagement. The cable is not designed for external deployment or hot-plug backplane scenarios. Incorrect directionality or unsupported controller firmware will result in undetected drives.

Questions about this item

Will the SFF8643 connector or SFF8482 29pin ports need periodic replacement?

The latching connectors are designed for secure lock-in and long-term enterprise use; no periodic replacement is required under normal server operation.

What is the first limit reached during sustained 12Gbps SAS3.0 transfers?

The per-port 12Gbps bandwidth ceiling of the SAS 3.0 standard is the primary throughput limit during continuous high-speed operation.

How much heat or noise does the shielded cable add during 24hour server runs?

The passive shielded wiring produces no noise and negligible heat; it is built for stable 24hour enterprise-grade operation without active cooling.
