2 Pack SFF-8644 to SFF-8643 Mini SAS HD Storage Cable 1M(3.3FT), External to Internal Mini SAS HD Data Wire for Server RAID Controllers, HDD & NVMe Backplanes

This package contains 2 pieces of 1-meter (3.3 feet) Mini SAS HD cross-type data cables. Each cable is fitted with an external SFF-8644 Mini SAS HD male connector on one end and an internal SFF-8643 Mini SAS HD male plug on the other, seamlessly connecting external RAID HBA host ports to server internal hard drive and NVMe storage backplanes.

Constructed with standard 28AWG impedance-controlled twin-axial copper conductors and dual-layer aluminum foil shielding, this cable effectively blocks electromagnetic interference and minimizes signal attenuation, delivering consistent 12Gbps per-lane high-speed transmission under continuous heavy read-write loads. It fully complies with SAS 3.0 industrial standards and maintains full compatibility with legacy SAS 2.0 and SAS 1.0 HDDs, SSDs and hot-swap drive bays.

All contact pins on both connectors are gold-plated to optimize electrical conductivity and resist long-term oxidation. Built-in snap locking latches firmly secure the cable interfaces to prevent loose connections triggered by rack cabinet vibration. The flexible lightweight outer jacket enables neat internal and rack cable arrangement without obstructing cooling airflow.

Suitable for enterprise rack servers, DAS direct-attached storage arrays, professional workstations and small business backup RAID systems. Plug-and-play design works perfectly with Windows Server, Linux and mainstream desktop operating systems. The 2-pack design meets demands for multi-array deployment, dual-server expansion and spare replacement storage wiring.
