Two-pack 0.5 m SFF-8643 to SATA breakout

This BUCIER two-pack provides two internal SFF-8643 to 4 SATA breakout cables, each 0.5 m long. They connect a single Mini-SAS HD 12 Gbps HBA or RAID controller port to four SATA hard drives or SSDs. The cables use 30 AWG conductors with braided sleeving and feature locking latches on both ends for secure retention.

Suits RAID or HBA expansion, not backplane SFF-8643

These cables are designed for builders adding SATA drives to a Mini-SAS HD 8643 host port on a controller or motherboard. They will not work if the target backplane or enclosure presents an SFF-8643 connector, because the host-side plug is male SFF-8643 and the breakout end is four SATA females. Buyers needing SFF-8643 on both ends or a reverse breakout should look elsewhere.

12 Gbps SAS host to 6 Gbps SATA target

The host-side SFF-8643 interface supports SAS 12 Gbps signalling, while each of the four SATA connectors operates at up to 6 Gbps per drive. This asymmetry decides whether the cable matches your controller and drive speeds. Verify that your HBA or RAID card exposes an internal SFF-8643 port and that your drives are SATA before installing.

Questions about this item

What controller or motherboard port do I need to plug the SFF-8643 end into?

The cable requires a 12Gbps SAS HBA or RAID controller with an internal HD Mini-SAS SFF-8643 male port.

Will the 6Gbps per-drive limit bottleneck my older 3Gbps SATA drives?

Each of the four SATA 7-pin female connectors runs at up to 6Gbps, so 3Gbps drives will operate at their native speed without bottleneck.

How can I verify the link is running at 6Gbps after installation?

Check the controller BIOS or OS disk utility; each attached drive should report a negotiated SATA 6Gbps link speed.
