Host-Side SFF-8643 Connection

This BUCIER breakout cable links a single SFF-8643 host port on a SAS RAID controller or motherboard to four SATA drives. The 3.3 ft length uses 30 AWG copper conductors rated for 6 Gb/s per drive. Locking latches on both the Mini-SAS HD plug and the four SATA 7-pin receptacles keep connections secure inside a chassis. It is built for internal storage expansion in DIY and professional systems.

Suits SAS-Controller Builds.

The cable works when the SFF-8643 connector sits on the controller or HBA side of the link. Builders attaching SATA SSDs or HDDs to a 12 Gb/s SAS HBA or RAID card will find the forward-breakout wiring correct. It will not function if the SFF-8643 port is located on a backplane, because the pinout assumes the host is the Mini-SAS HD end. Users needing a backplane-to-controller cable should select a different pinout.

SFF-8643 Male Host to Four SATA Female Targets

The decisive specification is the fixed host-to-target direction: one SFF-8643 male plug designated for the controller, splitting to four SATA 7-pin female connectors for drives. Reversing this orientation by plugging the SFF-8643 end into a backplane prevents the link from operating. Verify that your controller presents an SFF-8643 host port before purchasing.

Questions about this item

What does the 6 Gbps per-drive speed mean when the cable is connected to four drives?

Each of the four SATA connectors can carry up to 6 Gbps, so the total bandwidth depends on the controller and how many drives are active at once.

The cable mentions a 12 Gbps SAS controller side — what does that cap in practice?

The SFF-8643 host connector is rated for 12 Gbps SAS, but the SATA breakout limits each drive to 6 Gbps, so the link runs at SATA III speeds.

What clearance or mounting features does the 3.3 ft cable need to fit inside a typical case?

The 30 AWG wires are thin and flexible, and both the SFF-8643 plug and the four SATA plugs have locking latches that need a few millimetres of space to engage.
