Vszerda SFF-8644 to 4x SFF-8482 SAS cable 3.3ft 2-pack

Internal SAS breakout cable

This two-pack provides a 3.3 foot Mini SAS SFF-8644 to four SFF-8482 breakout with an integrated IDE power lead. It connects a single controller port to four SAS hard drives inside a personal computer. The assembly is compliant with the SAS 3.0 specification and rated for up to 6 Gbps, though actual throughput depends on the attached hardware. Builders expanding internal storage on a SAS backplane or HBA will find the pinout matches standard 29-pin drive connectors.

Build quality and daily handling

Each cable uses a male SFF-8644 plug on the controller side and four female SFF-8482 receptacles for the drives, with the IDE power connector running parallel for drive power. The 116-conductor construction supports the high-speed signalling required by the 6 Gbps link. At 3.3 feet the length suits typical chassis routing from a rear-mounted HBA to front drive bays without excessive slack. The moulded strain relief on each connector helps maintain signal integrity during routine drive swaps or case maintenance.

Thermals noise and power draw

As a passive copper assembly the cable generates no audible noise and adds negligible heat inside the enclosure. Power for the attached drives is supplied through the separate IDE connector, so the data path itself carries no significant current. The 6 Gbps rating is maintained across the full 3.3 foot run without active equalisation, keeping the link stable under continuous I/O workloads. No external power adapter or cooling is required for the cable itself.
