Type: Cable Adapter Main Control Chip: JMB582 Expansion Connection: 2 SATA3.0 6 Gbps ports Interface Speed: PCIE 3.0 Overview This cable adapter converts a PCIe 3.0 host connection into two independent SATA 3.0 ports. The JMB582 controller manages the two SATA channels, providing a straightforward way to add storage capacity to a compatible system without relying on builtin motherboard SATA headers. Key benefits Functional expansion: Adds two SATA III ports through a PCIe 3.0 interface, increasing available storage connections. Reliable control: Employs the JMB582 main control chip to manage dual SATA channels with standard SATA drives. data transfer capability: Each port supports up to 6 Gbps, enabling fast SATA storage performance. Compact, adapterbased design: Cable adapter form factor suited for desktop system builds and upgrades. Use scenarios Desktop storage expansion: Add two additional SATA drives to a PC via a PCIe slot to increase overall storage capacity for files, games, or media. Workstation upgrade: Attach extra drives to support larger datasets or multimedia projects without modifying existing motherboard ports. System retrofit or : Retrofit older systems with extra SATA connections to improve data accessibility and backup options using a PCIe 3.0 slot.
