Overview

Core Technical Specifications

1. Connector Layout

• Host End: 1 × Mini SAS HD SFF-8643 male connector with locking latch
• Drive End: 4 × SATA 7pin female connectors with retention clip, labeled HDD1–HDD4 for easy identification

2. Electrical Performance

• Per-port bandwidth: Up to 6Gbps SATA III, backward compatible with SATA I/II (1.5Gbps / 3Gbps)
• SAS 3.0 compatible, supports 12Gbps SAS signal transmission from controller
• Wire Gauge: 30AWG high-purity bare copper conductors
• Full aluminum foil shielding + braided outer sleeve for EMI/RFI interference suppression

3. Physical Parameters

• Total Cable Length: 0.5 Meter (50cm)
• Outer Jacket: Black woven mesh braided tube, flexible for neat chassis cable routing
• Connector Plating: Gold-plated pins for anti-oxidation and stable long-term contact

4. Compliance & Reliability

• RoHS, CE, FC certified
• Operating temperature: 0℃ ~ 70℃ for 24/7 server continuous operation
• Molded strain relief on both ends to prevent wire fracture during installation

Key Enterprise Features

1. High Density Storage Expansion
    
   Single SFF-8643 port expands to four SATA drives, reduces internal cable clutter and saves limited PCIe controller interface slots.
2. Secure Locking Connectors
    
   Built-in latches on both SFF-8643 and SATA plugs avoid accidental disconnection under rack vibration, stable for 24/7 data center operation.
3. Full Signal Isolation
    
   Independent shielded lanes eliminate cross-talk between four SATA channels, guarantee consistent performance under heavy concurrent read/write RAID workloads.
4. Wide Hardware Compatibility
    
   Fully compatible with LSI/Broadcom MegaRAID, Avago, Supermicro RAID/HBA cards equipped with SFF-8643 internal ports. Supports all 2.5”/3.5” SATA mechanical HDD and SATA SSD.
5. Space-Saving Design
    
   0.5M short length fits compact 1U/2U rack servers, improves internal airflow and cooling efficiency.

Important Notes

1. This cable only transmits data signals. Separate SATA power cables are required to supply power to each hard drive.
2. It is a forward breakout cable, do not reverse the wiring (SATA host to SAS backplane connection is not supported).
3. SAS hard drives cannot be recognized when connected to SATA-only controllers via this cable.
4. Each SATA port runs independently at full 6Gbps speed without bandwidth sharing bottlenecks.
