Adaptec SFF-8654 – 4x SFF-8639 U.3 Cable for Modern Storage Connectivity

This internal data cable from Adaptec connects an SFF-8654 host adapter to up to four U.3 drives via SFF-8639 connectors. It is specifically designed for servers, workstations and storage systems using SAS, SATA or NVME drives.

• 80 cm cable length provides enough slack for neat routing inside the chassis and reduces strain on the connectors.
• Four separate SFF-8639 outputs allow simultaneous operation of multiple drives on a single host port – ideal for space‑saving configurations.
• Supports both traditional SAS/SATA HDDs and modern NVME SSDs through the unified U.3 interface, ensuring maximum flexibility in drive mix.
• Straight (non‑angled) plugs fit standard ports and make insertion and removal easier in tight enclosures.

What sets this Adaptec cable apart

Adaptec is an established manufacturer of storage controller and connectivity solutions. This cable is tuned to the U.3 specification which unifies SAS, SATA and NVME on a single port – reducing complexity and increasing future‑proofness of storage infrastructures.

Ideal for...

System integrators, IT administrators and demanding PC builders who need to connect modern U.3 backplanes or drive cages with a suitable host adapter. Also suitable for building high‑performance NAS or server systems with mixed drive types.

How to use the cable

Plug the single SFF-8654 connector into the corresponding port on the host adapter. Connect the four SFF-8639 connectors to the U.3 drives or backplane ports. Ensure correct orientation – the latch clicks audibly into place. No additional configuration is required.
