Inter-Tech SFF 8643/4x SATA cable, 0.5m

Cable SFF-8643 to 4x SATA is a breakout cable designed to convert a single SFF-8643 mini-SAS HD connector into four standard SATA data connectors. It allows connection of up to four SATA drives to a host or controller with an SFF-8643 port, supporting common storage configurations in servers and workstations.

Advantages

The SFF-8643 to 4x SATA cable provides a compact, reliable method to connect multiple SATA drives without additional adapters. It simplifies wiring in tight rack or chassis environments and helps maintain signal integrity by using the direct mini-SAS HD interface on the host side. The cable is suitable for SATA SSDs and HDDs and is commonly used for storage expansion and drive replacement tasks.

Key specifications

• Connector (host): SFF-8643 (mini-SAS HD)
• Connector (device): 4 × SATA data (7-pin)
• Cable type: breakout/forward path cable
• Use case: connect up to four SATA drives to one SFF-8643 port
• Compatible with SATA SSDs and HDDs

How to use

Power off the system before connecting. Plug the SFF-8643 connector into the host or controller port, then attach each SATA connector to the corresponding drive data port. Ensure SATA power connections are provided separately from the power supply to each drive. After verifying connections, power on the system and check that the controller recognizes the connected drives.

Recommendations

Use the cable in environments where the controller supports SATA via SFF-8643. Avoid sharp bends and excessive tension on the cable to preserve signal quality. Verify compatibility with your controller and drives before installation.
