SlimSAS SFF-8654 4i plug to U.2 SFF-8639 connector, 50cm cable

Aomoproing

Aomoproing SFF-8654 4i to SFF-8639 U.2 esata cable 50cm

SKU CH-5J39-2R3VN

Connects a U.2 SFF-8639 device to a SlimSAS SFF-8654 4i controller at 24 Gbps over 50 cm

Cable Length 0.5m

  • 24 Gb/s SAS throughput moves large datasets fast
  • 50 cm cable length keeps internal routing tidy
  • PCIe 4.0 support enables high-bandwidth controller links
  • SFF-8654 4i to SFF-8639 U.2 connects SlimSAS to U.2 devices
  • 8 GT/s per channel delivers low-latency signal integrity

Connection Interface

This cable bridges a SlimSAS SFF-8654 4i host port to a U.2 SFF-8639 drive connector. It carries PCIe 4.0 and SAS signals at up to 24 Gbps per channel over a 50 cm length. The assembly is designed for internal chassis routing between a controller and a compatible drive backplane.

Target Builder

It suits integrators wiring a modern SlimSAS 4i controller to U.2 bays in servers or workstations. It will not serve builds that rely on legacy wide-port SAS plugs, standard 7-pin SATA headers, or external eSATA brackets. Buyers needing a different host-side pinout or a longer reach must source an alternative cable.

Decisive Specification

The host connector is a 4-lane SlimSAS SFF-8654 4i plug; the drive end is an SFF-8639 U.2 receptacle. Verify that both the controller and the drive bay present exactly these interfaces before ordering, as the cable does not adapt to other connector families.

Highlights

  • 24 Gb/s SAS throughput moves large datasets fast
  • 50 cm cable length keeps internal routing tidy
  • PCIe 4.0 support enables high-bandwidth controller links
  • SFF-8654 4i to SFF-8639 U.2 connects SlimSAS to U.2 devices

Questions about this item

What controller connector does the SFF-8654 4i end plug into?

The cable terminates in a SlimSAS SFF-8654 4i plug that mates with a matching controller port.

How do I connect the U.2 SFF-8639 end to the drive?

Align the SFF-8639 connector with the U.2 port on the drive and press straight in until the latch clicks.

When should I replace this 50cm cable?

Replace it if the latch fails to hold, the connector pins are bent, or signal errors appear during 24Gbps transfers.
