Mini SAS 36pin internal cable Mini SAS 36pin internal data cable that connects a PCIe controller with an SFF8087 port to four independent drives. Hard disk cable provides a reliable internal connection between a controller card in a computer system and a directly connected storage device. Rear identification marks P1 to P4 on the installation plate for easy identification from the rear. Ribbon cable design minimizes airflow obstruction inside the computer case. Why you need it Enables connecting four independent drives to a single PCIe controller via SFF8087. Improves internal wiring organization while reducing airflow disruption for better cooling. Compatibility and use Designed for PCIe controllers that use an SFF8087 internal port. Suitable for systems that require direct fourdrive connectivity from a controller card. Use scenarios Server storage expansion: connect a PCIe RAID/HBA controller to four drives within a server chassis. Professional workstation: attach four directly connected drives to a PCIe controller for capacity data processing. Small form factor or NAS build: wire four drives to a controller card to create a compact storage solution.
