SMUGDESK Mini SAS SFF8087 to 4Port SFF8482 Breakout Cable with Power Supply 50CM

Breakout Cable for Multi-Drive SAS Expansion

This breakout cable converts a single SFF8087 Mini SAS port into four SFF8482 connectors, enabling connection of multiple SAS hard drives to a single controller port. It targets system builders and IT administrators expanding storage capacity inside enterprise servers or RAID enclosures. The integrated power supply ensures drives receive stable current directly through the cable assembly. It is not suited for installations requiring longer internal routing distances beyond the fixed short length.

Sustained Signal Integrity with Shielded Conductors

Premium conductors and robust anti-interference shielding maintain consistent high-bandwidth data transmission across all four channels during continuous heavy I/O workloads. The design minimises electromagnetic interference, signal loss and crosstalk that can degrade performance in dense multi-drive environments. Stable power delivery from the built-in supply prevents voltage drops that might otherwise cause drive errors during prolonged rebuilds or parity checks. The fixed 50cm length limits deployment to compact chassis configurations.

Passive Cooling and Efficient Power Distribution

The cable assembly operates without active cooling components, relying on the server chassis airflow for thermal management during normal use. Power draw is determined by the connected SAS drives rather than the cable itself, which adds negligible resistance to the circuit. No fan noise is introduced, preserving the acoustic profile of the host system. The compact form factor avoids obstructing airflow paths around densely populated drive bays.
