Two-pack SFF-8643 to SATA breakout cables
This two-pack provides forward breakout cables that connect a single SFF-8643 Mini-SAS HD port on a RAID controller or motherboard to four SATA drives. Each cable carries four labelled SATA 7-pin connectors, simplifying internal cable routing in storage expansion scenarios. The set is aimed at builders adding multiple SATA hard drives to a high-density SAS host interface.
12 Gbps host link with 6 Gbps per SATA drive
The SFF-8643 host connector supports a 12 Gbps SAS HBA or RAID controller link, while each of the four SATA targets operates at up to 6 Gbps. This headroom covers typical SATA SSD and HDD workloads without saturating the host lane. The forward breakout design means the cable will not function if the SFF-8643 end is plugged into a backplane instead of the controller.
Low-profile thin cable aids airflow
The 12 G high-speed SAS thin cable construction reduces bulk inside the chassis, helping maintain clear airflow paths around drives and controllers. Locking latches on the SFF-8643 plug and standard SATA latches on the drive ends keep connections secure under vibration. No active cooling or external power is required for the cable assembly itself.

Questions about this item
Will the SFF-8643 connector fit the 12 Gbps SAS HBA I already have?
The SFF-8643 host end plugs into a 12 Gbps SAS HBA or RAID controller and breaks out to four SATA drives.
How can I confirm the cable is delivering 6 Gbps per drive after installation?
Check the controller BIOS or OS disk utility — each attached SATA drive should negotiate a 6 Gbps link speed.
The pack says 2Pack; does that mean two complete breakout cables or just one?
The pack contains two separate SFF-8643 to 4×SATA breakout cables, each 3.3 ft long.
