Short MiniSAS HD SFF-8643 cable fanning out to four SFF-8482 connectors with Molex and SATA power plugs

SMUGDESK

SMUGDESK MiniSAS HD SFF-8643 to 4×SFF-8482 Fan-Out SAS Cable 0.5m 12Gbps

SKU CH-AADM-B06SK

Connects one SFF-8643 MiniSAS HD port to four SFF-8482 SAS or SATA drives at 12Gbps with integrated Molex and SATA power connectors in a 0.5m shielded cable

  • Splits one SFF-8643 port into four SFF-8482 drive connections for simultaneous SAS or SATA hard disk attachment
  • Delivers 12Gbps per channel bandwidth under SAS 3.0 protocol for high-throughput RAID array and storage server workloads
  • Integrated IDE Molex plus 15-pin SATA power branch supplies stable voltage directly from the server PSU without extra power cords
  • Compact .5 metre length keeps dense rack cabinet internal wiring tidy and unobstructed for airflow dissipation
  • Shielded industrial-grade cable reduces signal crosstalk and interference for stable 24-hour continuous storage operation

Target Use

This SMUGDESK MiniSAS HD breakout cable connects a RAID HBA controller with an SFF-8643 port to four SAS or SATA hard drives. It is built for server and storage deployments that need to wire multiple 2.5 or 3.5-inch drives from a single host port. The integrated dual power interface feeds drives directly from the server supply, removing the need for separate power cables in dense cabinets.

Thermals and Power

The 0.5 metre length keeps internal routing short, which helps maintain airflow inside the chassis for heat dissipation. Shielded construction reduces signal crosstalk during continuous 24-hour operation, supporting stable data transfer without extra cooling demands. Power is drawn through the onboard Molex and 15-pin SATA connectors, so drive voltage comes straight from the server power supply module.

Deciding Specification

The cable splits one SFF-8643 input into four independent SFF-8482 connectors, each running at 12Gbps under the SAS 3.0 protocol. This single-lane bandwidth figure determines whether the link matches your controller and drive throughput requirements. Buyers who need more than four drive connections or a different host connector type cannot use this assembly.

Questions about this item

How do I plug the SFF-8643 end into my RAID controller and the four SFF-8482 ends into my drives?

Insert the single SFF-8643 connector into the controller's internal MiniSAS HD port, then attach each of the four SFF-8482 plugs to a SAS or SATA 2.5/3.5-inch drive; the step often missed is connecting the integrated 4-pin Molex or 15-pin SATA power branch to the PSU so the drives actually receive power.

Will the Molex or SATA power connector on the cable wear out and need replacement?

The integrated 4-pin Molex and 15-pin SATA power interfaces are built into the cable assembly and rated for continuous 24-hour operation; they do not have a separate replacement schedule unless physical damage occurs.

At what point does the 12Gbps per channel limit appear during heavy RAID 5 or RAID 6 rebuilds?

The cable is fully compliant with SAS 3.0 at 12Gbps per channel, so the bandwidth ceiling is reached only when the controller or drives saturate that 12Gbps link during sustained high-throughput rebuilds.
