Mini SAS HD to U.2 connectivity
This 0.5 metre cable links a SFF-8643 Mini SAS HD host port to a SFF-8639 U.2 solid-state drive inside a server or workstation chassis. It targets system builders and IT professionals who need a direct internal data path for high-performance U.2 storage without extra adapters. The integrated 15-pin SATA power connector supplies the drive from the system power supply in a single assembly.
12Gbps SAS bandwidth ceiling
The cable is rated for 12Gbps SAS signalling, which sets the maximum throughput for any attached U.2 drive. Actual transfer speed will not exceed this interface limit regardless of the drive’s own capability, so workloads demanding higher bandwidth will be constrained by the link. Signal integrity depends on the full-shield construction and the short 0.5 metre run inside the enclosure.
Locking connectors and shielded routing
Precision locking mechanisms on both the SFF-8643 and SFF-8639 ends resist disconnection caused by chassis vibration or drive-tray movement. Multi-layer shielding around high-purity copper cores suppresses electromagnetic interference from neighbouring components. The bundled wire body keeps internal cabling tidy, preserving airflow and simplifying future hardware changes in dense server environments.

Questions about this item
Is the .5 meter length right for my chassis?
The .5 meter cable reaches between a SFF-8643 Mini SAS HD host port and a SFF-8639 U.2 drive bay in most standard server and workstation chassis, keeping routing tidy without excess slack.
What does 12Gbps mean for my U.2 SSD?
12Gbps SAS bandwidth provides the full interface speed current U.2 SSDs can use, so sustained reads and writes are not limited by the cable during heavy workloads.
Does the 15-pin SATA power connector work with my PSU?
Yes, the 15-pin SATA power plug draws standard SATA power from your PSU and delivers it directly to the U.2 drive, so no separate power adapter is needed.
