SFF-8639 to SFF-8482 RAID Cable

This 30 cm adapter cable bridges an SFF-8639 SATA Express 18-pin device connector with a 15-pin SATA power plug to an SFF-8482 SAS Express 29-pin host connector. It is built for installers who need to attach a SATA Express SSD to a matching host port inside a workstation or server chassis.

Shielded 26 AWG Construction

The cable uses 26 AWG conductors wrapped in shielding to protect signal integrity across the short run. Three distinct connectors — 18-pin SATA Express, 15-pin SATA power, and 29-pin SAS Express — are moulded in a single black assembly, so routing stays tidy in tight drive bays or backplanes.

PCIe 2.0 or 3.0 Lane Support

Data moves at up to 1 GB/s over PCI Express 2.0 lanes or 2 GB/s over PCI Express 3.0 lanes, with AHCI and NVMe protocol support. The part only works when both the host system and the SSD expose native SATA Express ports; it cannot connect legacy SATA or standard SAS devices.

Questions about this item

What data rate does the SATA 3.2 Express interface on this cable cap at?

The cable supports up to 1 GB/s over PCI Express 2.0 or up to 2 GB/s over PCI Express 3.0, depending on the host port revision.

What connectors and clearance does the 30 cm cable need to fit?

It requires a SATA Express 18-pin (7+7+4) male, a SATA 15-pin power male, and a SFF-8482 SAS 29-pin (15+7+7) male connector; the assembly is about 30 cm long excluding the plugs.

How is the cable installed and which orientation mistake is common?

Connect the 18-pin and 15-pin plugs to the SSD and the 29-pin plug to the motherboard SATA Express port; the keyed 18-pin and 29-pin connectors only seat one way, so forcing them reversed is the typical error.
