1-meter SFF-8643 Mini SAS HD cable splitting into four SFF-8482 connectors with SATA power leads

SMUGDESK

SMUGDESK 1M (3.3FT) SFF-8643 to 4X SFF-8482 SAS Cable with SATA Power

SKU CH-08QA-B8MXV

Converts one SFF-8643 Mini SAS HD port into four SFF-8482 channels with SATA power for 2.5 or 3.5 SAS drives at 12Gbps

  • Connects RAID controller to four SAS drives via single Mini SAS HD port
  • Delivers 12Gbps per channel bandwidth compliant with SAS 3.0 standard
  • Integrated SATA power connectors supply drives directly, reducing internal cable clutter
  • Locking latch connectors prevent accidental disconnection during server operation
  • 1-meter length with reinforced strain relief allows flexible routing in 2.5 / 3.5 drive bays

Internal Server Storage Breakout

This SFF-8643 to four SFF-8482 breakout cable connects a single Mini SAS HD port on a RAID controller or HBA to four SAS hard drives inside a server chassis. Integrated SATA power connectors supply the drives directly, reducing internal cable count. The one-metre length allows flexible routing in rackmount enclosures and storage workstations. Locking latches on every connector resist vibration-induced disconnection.

Capacity and Headroom

Each of the four channels supports SAS 3.0 signalling at up to 12Gbps, providing ample bandwidth for database workloads, mass data access and backup operations. Multi-layer shielding limits crosstalk in dense wiring environments. The cable cannot power or signal pure SATA drives without an adapter, so buyers needing direct SATA attachment should look elsewhere. It is built for 2.5 and 3.5 SAS drives with SFF-8482 interfaces.

SAS 3.0 Interface Limits

The SAS 3.0 standard caps per-lane throughput at 12Gbps, so aggregate performance scales with the number of active drives and controller capability. Cable length and shielding quality become critical as lane speeds rise; this assembly uses reinforced strain relief to protect conductors during installation. Systems requiring higher lane rates or different connector form factors will need alternative cabling solutions.

Highlights

  • Connects RAID controller to four SAS drives via single Mini SAS HD port
  • Delivers 12Gbps per channel bandwidth compliant with SAS 3.0 standard
  • Integrated SATA power connectors supply drives directly, reducing internal cable clutter
  • Locking latch connectors prevent accidental disconnection during server operation
  • 1-meter length with reinforced strain relief allows flexible routing in 2.5 / 3.5 drive bays

Questions about this item

Will the 1-meter SFF-8643 breakout cable reach drives in a 4U server while keeping the 12Gbps SAS 3.0 signal clean?

The 1-meter length provides flexible routing inside rackmount chassis, and multi-layer shielding minimises electromagnetic interference to maintain consistent 12Gbps throughput per channel.

How can I verify each of the four SFF-8482 links is running at full 12Gbps after connecting the RAID controller?

Check the controller BIOS or management utility for negotiated link speed; each port should report 12Gbps with zero CRC errors during sustained I/O.

Does the package include the SATA power leads needed for four 3.5-inch SAS drives, or must I buy a separate power splitter?

The cable has integrated SATA power connectors that deliver power to the attached drives, so no extra power splitter is required for standard 3.5-inch SFF-8482 SAS drives.
