  • 6 ft length fits compact chassis
  • Two cables included for dual-port setups

Internal SAS HD cable pair

This two-pack provides SFF-8643 to SFF-8643 connections for internal storage links. Each assembly measures 2.6ft and carries a 100-Ohm impedance rating. The cables support data rates up to 12Gbps for SAS 3.0 and 6Gbps for SAS 2.1. Builders needing longer runs or external connectors will need a different solution.

Thermals noise and power draw

Passive copper construction adds no active cooling requirement and generates no audible noise. Power draw is limited to the signal circuitry of the attached controller and backplane. The 30 AWG conductors maintain signal integrity at 12.00 Gb/s without additional power overhead. No fan headers or external power adapters are involved.

Build quality and daily use

Black 30 AWG wire and moulded SFF-8643 ends survive repeated seating in dense backplanes. Sideband pins are wired for enclosure management and SGPIO functions. The 0.8-metre length fits typical 2U and 4U chassis routing without excess slack. RoHS compliant materials meet standard environmental requirements.

Questions about this item

How do I install the SFF-8643 connectors and what step is often missed?

Align each SFF-8643 plug with the internal Mini SAS HD port and press straight in until the latch clicks; the step often missed is failing to engage the sideband pins, which carry management signals.

What maintenance or replacement will this 30 AWG cable need later?

Inspect the 30 AWG conductors and latch tabs during any chassis service; replace the pair if you see bent pins, cracked housings, or intermittent 12.00 Gb/s link errors.

What limit appears first under sustained 12 Gbps use?

The 0.8 metre length and 100 Ohm impedance maintain signal integrity, so the first limit is usually the host controller’s thermal throttle or backplane bandwidth, not the cable itself.
