SFF-8644 to 4×SFF-8482 SAS 3.0 cable

This 6.6 ft cable connects a Mini SAS HD SFF-8644 port to four SFF-8482 connectors. It is built for servers, storage arrays and switches that need external 12 Gbps SAS links. Installers and system integrators use it to break out a single 4X controller port to multiple drives or backplanes.

Sustained 12 Gbps throughput across four lanes

Each of the four lanes runs at 3 Gbps per lane for an aggregate 12 Gbps rate under the SAS 3.0 specification. The cable maintains this bandwidth during continuous array rebuilds, bulk transfers and RAID parity calculations without dropping to a lower signalling speed.

Passive design keeps thermals and noise negligible

No active components draw power or generate heat, so the link adds no measurable thermal load to the chassis. Operation is silent, and the only power consideration is the minimal insertion loss inherent in a 2 m passive copper assembly.

Questions about this item

Does the SFF-8644 to 4 x SFF-8482 cable generate noticeable heat or draw extra power during all-day server use?

The cable is a passive copper assembly with no active components, so it adds no measurable heat or power draw beyond the signal itself.

What host connector must my RAID card or HBA provide for this SFF-8644 plug to mate correctly?

The host side requires an external Mini SAS HD SFF-8644 receptacle, the standard 4-lane 12Gbps port found on modern SAS 3.0 RAID cards and HBAs.

Can I attach older 3Gbps or 6Gbps SAS drives to the four SFF-8482 ends without changing cables?

Yes, each SFF-8482 connector follows the SAS 3.0 spec and is backward compatible with 3Gbps and 6Gbps SAS or SATA drives.
