Product Overview

This product expands two independent PCIe x4 slots through a single USB4 interface. By installing two PCIe-to-4-port SATA expansion cards, the hub can be converted into an 8-port SATA 6Gbps storage expansion hub, supporting connections for up to 8 SATA-interfaced solid-state drives (SSDs) or hard disk drives (HDDs). Ideal for high-speed external storage arrays, media libraries, video editing cache pools, data backup, and capacity expansion scenarios.
