Cable Adapter for PCIe to 2x SATA Ports Key specifications Interface speed: PCIE 3.0 Main control chip: JMB582 Expansion connection: 2 SATA3.0 6Gbps Type: Cable Adapter Why you need this Adds two SATA 3.0 drives via a PCIe slot, increasing storage capacity without needing a larger motherboard or enclosure upgrade. Uses the JMB582 controller for reliable SATA drive management and compatibility with standard SATA devices. Each port supports up to 6Gbps, enabling fast data transfer for HDDs and SSDs that use SATA. What makes it stand out Simple cable adapter form factor designed to expand storage without complex setup. Dual SATA 3.0 ports provide a practical upgrade path for desktops with limited native SATA headers. PCIe 3.0 compatibility ensures broad motherboard support and adequate bandwidth for typical SATA drives. Compatible use scenarios Desktop expansion: Install in a PC with an available PCIe slot to add two SATA HDDs or SSDs for data storage, backups, or media libraries. Media server/backup node: Create a compact storage solution by connecting two SATA drives to an existing system with spare PCIe bandwidth. motherboard port replacement: If onboard SATA ports are insufficient or failing, use this PCIe adapter to access two additional SATA drives without motherboard changes. Notes This device provides two SATA 3.0 (6Gbps) expansion ports through a PCIe 3.0 interface using the JMB582 controller. Type: Cable Adapter.
