Internal Mini SAS HD SFF-8643 to 4 SATA Internal Cables 600mm

‌Internal Mini SAS HD SFF-8643 to 4× SATA Internal Cable – 600 mm

This internal breakout cable converts a single Mini SAS HD (SFF-8643) host port into four discrete SATA 7-pin connectors, allowing you to attach up to four SATA hard drives or SSDs to a SAS / RAID / HBA controller. The 600 mm length provides ample reach inside mid-tower and server chassis while maintaining signal integrity for high-speed storage applications.

Technical Description

Interface A (Host):

– 1× Internal Mini SAS HD connector, SFF-8643, 36-pin

– Typically mates with SAS 12G controllers, RAID cards, HBAs, and backplane inputs

Interface B (Device Side):

– 4× standard SATA 7-pin receptacle connectors

– Supports SATA HDDs and SSDs (SATA I 1.5 Gb/s, SATA II 3 Gb/s, SATA III 6 Gb/s)

Cable Type & Performance:

– High-speed, multi-lane internal SAS cable designed to support up to 12 Gb/s SAS signaling (depending on controller and drive capabilities)

– Individually shielded twin-ax pairs within an overall shield to minimize crosstalk and EMI

– Low-skew, low-loss construction for reliable performance at high data rates

Length:

– 600 mm (60 cm) overall cable length, optimized for clean, direct routing inside rackmount and tower server enclosures

Construction:

– Robust molded Mini SAS HD and SATA terminations for secure mating and long-term reliability

– Flexible, yet durable cable jacket for easy cable management in dense systems

– Correct lane mapping from SFF-8643 to each SATA port for plug-and-play operation with compliant controllers

Typical Uses

Connecting a 12G/6G SAS or RAID controller with an internal Mini SAS HD (SFF-8643) port to up to four SATA drives in a workstation, NAS, or server.

Upgrading or expanding storage arrays where a single Mini SAS HD port needs to be broken out to individual SATA devices.

Ideal for high-density storage builds that require neat, reliable internal cabling with consistent 600 mm reach.
