Blue 1m cable with 38pin SFF8654 4i connector splitting to two SFF8482 ports and SATA power plug

SMUGDESK

SMUGDESK PCIe Slimline SAS 4.0 38Pin SFF8654 4i to SFF8482 2in1 Cable with SATA Power 1m

SKU CH-A6T4-1Q8FK

Converts a single 38-pin SFF8654 4i port to dual SFF8482 drive ports with integrated SATA power for 24 Gbps NVMe, SAS and SATA storage

  • Single cable splits one SFF8654 4i port into two SFF8482 drive connections
  • Built-in SATA power line removes the need for separate drive power cables
  • 30AWG low-loss copper delivers stable 24Gbps bandwidth for SAS, SATA and NVMe drives
  • 1 metre length allows tidy routing inside servers, NAS units and storage backplanes
  • PCIe 4.0 compliant shielding cuts interference for reliable long-term enterprise performance

PCIe 4.0 Slimline SAS breakout cable

This PCIe 4.0 Slimline SAS breakout cable adapts a single 38-pin SFF8654 4i port into two SFF8482 drive connectors with an integrated SATA power line. It serves builders who need to connect multiple SAS, SATA or NVMe drives from one controller port in servers, NAS enclosures or workstation storage backplanes. The 1 m length supports flexible internal routing.

24 Gbps bandwidth limit over copper

The 30AWG low-loss copper harness is rated for 24 Gbps transmission, which defines the practical throughput ceiling for attached drives. Signal integrity relies on the shielding built into this 1 m assembly; longer runs or additional adapters would reduce the usable margin. The cable carries data only and does not perform protocol conversion.

Replaces separate data and power looms

This assembly replaces a separate SFF8654-to-SFF8482 data cable plus a discrete SATA power cable, reducing internal clutter and connection points. The upgrade is worth it when a backplane or enclosure provides SFF8482 bays but the host adapter only exposes Slimline SAS ports. It does not add controller ports or increase the number of drives a single controller can address.

Questions about this item

Which breakout style should I choose for connecting one SFF8654 4i port to two drives?

The 2in1 breakout design splits a single SFF8654 4i port into two SFF8482 connectors so you can attach two drives from one controller port.

What does the 24Gbps rating mean when the cable is installed in a server?

The 30AWG lowloss copper harness sustains 24Gbps throughput for NVMe, SAS and SATA drives, delivering full PCIe 4.0 bandwidth to each connected device.

How does the SFF8654 4i interface limit performance in practice?

The SFF8654 4i connector carries four lanes of PCIe 4.0, capping each lane at the 24Gbps signal rate supported by the 30AWG copper construction.
