Black flat 1m cable with SFF8654 38P connector splitting to four SATA plugs

SMUGDESK

SMUGDESK 1M Slimline SAS SFF8654 4i 38P to 4X SATA Cable

SKU CH-S931-9JX37

Converts one SFF-8654 38-pin Slimline SAS port into four SATA connectors for multi-drive expansion

  • Converts one Slimline SAS port into four SATA drives
  • 10 ohm impedance-matched wiring minimises signal loss and crosstalk
  • 30 AWG pure copper conductors maintain signal integrity over distance
  • Flat-to-flat black design enables tidy routing in dense server chassis
  • 1 metre length suits medium-range connections in enterprise storage arrays

1M Slimline SAS SFF8654 4i Fanout Cable

This 1 metre cable converts a single SFF8654 4 lane 38 pin Slimline SAS port into four SATA connections for multi drive expansion. It is built for RAID controllers, enterprise storage arrays and high density NAS deployments that need reliable internal connectivity. The 30AWG pure copper conductors and 10 ohm impedance matched flat to flat wiring maintain signal integrity across the link. Black server grade jacket keeps routing tidy inside rackmount chassis.

Installation Notes and Common Issues

The flat to flat design allows neat cable management in tight server backplanes without blocking adjacent slots. Ensure the SFF8654 connector is fully seated on the controller side to avoid intermittent drive detection. Verify that each SATA plug clicks securely into the drive backplane or SSD. Mismatched port orientation or bent pins on the 38 pin header are the most frequent cause of link errors.

Capacity and Headroom

Four SATA drives share the bandwidth of one 4 lane Slimline SAS interface, so aggregate throughput scales with the controller and drive capabilities. The cable handles typical enterprise HDD and SSD workloads in RAID 0, 1, 5 or 10 configurations. Extremely heavy simultaneous write streams across all four drives may saturate the upstream SAS link depending on the controller generation. For larger drive counts, additional fanout cables or a wider SAS port are required.

Questions about this item

How can I verify the 10ohm impedance-matched cable is working correctly after connecting it to an SFF8654 4i port?

The system BIOS or RAID controller should detect each attached SATA drive on all four connectors without errors, confirming stable highspeed data transmission.

What comes with the cable and do I need separate SATA power cables for the drives?

The package includes the 1meter fanout cable with one 38pin SFF8654 4i plug and four SATA data connectors; SATA power cables for each drive must be sourced separately.

Which version of this cable should I choose for a 4lane Slimline SAS port?

This model is specifically built for SFF8654 4lane 38pin ports, converting one interface into four SATA connections using 30AWG copper wiring.
