Vszerda SFF-8644 to SlimSAS 4i Cable

This 0.5m copper twinax cable connects an SFF-8644 Mini SAS HD port to a SlimSAS 4i SFF-8654 connector. It supports 12 Gbps SAS 3.0 data rates with 100-ohm impedance for stable signal integrity. The male-to-male design suits internal server and storage links where space is tight. Builders assembling RAID arrays or JBOD enclosures will find the high-density layout practical.

Check connector types and lane count before ordering

Verify that your controller or backplane presents an SFF-8644 receptacle and that the target device accepts an SFF-8654 plug. Confirm the system requires a four-lane internal cable rather than an eight-lane or external variant. The half-metre length limits routing to adjacent bays or short intra-chassis runs. Ensure the chassis airflow path can accommodate the cable bend radius without sharp kinks.

Replaces older 6 Gbps Mini SAS HD interconnects

Upgrading from 6 Gbps SAS 2.0 cables doubles per-lane bandwidth to 12 Gbps without changing the controller form factor. The SlimSAS 4i connector reduces bulk compared to legacy SFF-8644-to-SFF-8644 looms, freeing room for additional drives. The jump is worth it when drive throughput saturates the 6 Gbps link or when density demands a slimmer cable profile.

Questions about this item

Does the package include the SFF-8644 to SFF-8654 cable only or are mounting brackets also supplied?

The box contains the 0.5 m copper twinax cable with male SFF-8644 and male SFF-8654 ends; brackets or screws are not included.

When should I pick the 0.5 m length over a longer cable for my SAS 3.0 link?

Choose 0.5 m for short runs inside a single chassis where excess length would block airflow; longer cables add latency and signal loss.

What does the 12 Gbps per lane rating mean for throughput in a RAID array?

Each lane runs at up to 12 Gbps, so a four-lane link delivers the full SAS 3.0 bandwidth the controller and drives negotiate.
