Short black fan-out cable with silver SFF-8643 plug splitting to four SFF-8482 connectors and Molex SATA power leads

SMUGDESK

SMUGDESK 0.5m 12Gbps Mini SAS HD SFF-8643 to 4× SFF-8482 Fan-out Cable with Molex SATA Power

SKU CH-3G17-F65QB

Connects one 12 Gbps SAS controller to four drives with integrated Molex and SATA power

  • SFF-8643 to four SFF-8482 ports connects four drives
  • 12Gbps SAS bandwidth handles heavy multi-disk workloads
  • Integrated Molex and SATA 15Pin power removes extra cables
  • .5m length keeps chassis airflow clear
  • Double-layer shielding ensures stable 24/7 RAID operation

Connection Layout

This cable splits a single SFF-8643 Mini SAS HD port into four independent SFF-8482 connectors. It allows one controller channel to drive four SAS or SATA hard drives simultaneously inside servers or storage arrays. The 0.5-metre length keeps internal routing tidy and supports airflow.

Transfer Rate

The assembly complies with the SAS 3.0 protocol to deliver up to 12Gbps bandwidth per lane. This throughput handles multi-disk concurrent access, backup workloads and virtual machine disk operations without bottlenecks. Multi-layer aluminium foil and braided shielding resist electromagnetic interference for stable 24/7 operation.

Integrated Power

Built-in Molex 4-pin and SATA 15-pin connectors supply drive power directly from the server PSU, removing the need for separate power cables. Buyers whose drives require only SATA power or whose chassis already provides dedicated backplane power should look elsewhere. Builders needing longer reach or external bulkhead connections will need a different harness.

Questions about this item

How does the 12Gbps rating affect real-world throughput when four drives are active?

The 12Gbps bandwidth is shared across the four SFF-8482 ports, so sustained throughput per drive depends on simultaneous I/O load and controller queue depth.

What SAS standard does the SFF-8643 connector follow and what speed ceiling does it enforce?

The SFF-8643 plug complies with the SAS 3.0 12Gbps protocol, capping the link at 12Gbps per lane for all connected drives.

Will the 0.5m length and Molex plus SATA power plugs fit a standard 3.5-inch drive bay?

The 0.5m harness reaches typical backplane-to-controller routes, and the combined Molex and 15-pin SATA power connectors feed 3.5-inch drives directly.
