Vszerda U.2 SFF-8639 to Slimline SFF-8654 4i NVME SAS cable 50cm

SKU CH-WD36-MV6MV

Connects a U.2 SFF-8639 device to a Slimline SFF-8654 4i controller for NVME SAS drives, 50cm length

Cable Length 50 cm

  • Connect U.2 drives to Slimline controllers using SFF-8639 to SFF-8654 4i interface
  • 50 cm cable length fits compact server and workstation chassis
  • Supports NVME and SAS protocols for high-speed storage links
  • Compatible with M.2 SFF-8643 Mini SAS HD devices for versatile connectivity
  • Cable-only design lets you pair with existing adapters or controller cards

Connecting U.2 and Slimline SAS

This cable bridges a U.2 SFF-8639 port to a Slimline SFF-8654 4i connector. It enables NVME SAS links between internal storage devices and compatible controllers. The assembly measures 50 centimetres end to end. It is aimed at builders integrating mixed-connector storage in servers or workstations.

Verify connector types before ordering

Confirm the host side presents a Slimline SFF-8654 4i receptacle and the drive side uses SFF-8639. The cable does not adapt M.2 SFF-8643 Mini SAS HD directly; that interface requires a different pinout. No controller card or drive adapter is included in the package. Ensure your chassis routing can accommodate the fixed length.

Straight plug-to-plug construction

Both ends use moulded straight connectors for a secure latch on each port. The 50 centimetre run keeps cable management tidy in dense drive bays. Shielded conductors preserve signal integrity for NVME SAS traffic. The design suits permanent internal installation without strain relief concerns.

Questions about this item

Does the cable include a U.2 SFF-8639 drive or a Slimline SFF-8654 4i controller card?

The package contains only the 50 cm cable with a U.2 SFF-8639 connector on one end and a Slimline SFF-8654 4i plug on the other; the NVMe SSD and the host adapter must be purchased separately.

How do I know whether my drive uses the SFF-8639 or SFF-8643 interface so I can pick the correct cable?

Check the physical port on your SSD; a U.2 NVMe drive presents an SFF-8639 receptacle, while a Mini SAS HD device uses SFF-8643, and this cable mates only with the SFF-8639 side.

Will this 50 cm link support full NVMe throughput when I connect a U.2 SSD to a Slimline SFF-8654 4i HBA?

The cable carries four PCIe lanes between the SFF-8639 drive and the SFF-8654 4i controller, so NVMe performance is limited only by the drive and host capabilities, not by the 50 cm length.
