Features and benefits Expands storage: Adds two SATA ports (2 SATA3.06Gbps) to a system through a PCIE interface so you can connect two additional SATA drives without replacing the motherboard. speed interface: Uses PCIE3.0 for host connection to deliver consistent bandwidth between the system and attached drives. Reliable controller: Built around the JMB582 main control chip for stable signal management and drive compatibility. Simple form factor: Cable adapter design means flexible placement and easy routing inside typical PC cases. Why you need this adapter Quickly increase local storage capacity by adding two SATA drives when internal ports are limited. Avoid full system upgrades: add drives via a PCIE slot instead of changing the motherboard. Maintain system performance and drive stability through a dedicated controller (JMB582) rather than relying on overloaded onboard headers. Key attributes Function: Adapter to connect two SATA drives to a PCIE3.0 slot. Expansion: 2 SATA3.06Gbps ports for HDDs or SSDs that use SATA signaling. Interface speed: PCIE3.0 host connection. Main control chip: JMB582. Type: Cable adapter — flexible cabling for easier installation and neat internal layout. Compatibility and installation notes Designed for systems with an available PCIE3.0 slot and drives using SATA connectors. Cable adapter allows mounting flexibility; standard SATA connectors used for wide compatibility with 2.5' and 3.5' SATA drives. No special tools required beyond typical PC disassembly; route the cable and attach the drives to the provided SATA ports. Practical use scenarios Desktop expansion: Add two SSDs or HDDs to a desktop PC that has no SATA headers to increase storage for media, games, or backups. Home server or NAS retrofit: Add drives to a home server or DIY NAS to expand capacity without replacing the motherboard or buying a controller card. Workstation upgrade: Fit additional scratch or archive drives for video editing or CAD projects where extra local storage improves workflow. What it solves Eliminates the need to uninstall existing drives or the motherboard when more SATA ports are required. Provides a dedicated controller (JMB582) to manage additional drives, improving stability versus overtaxing onboard ports. Cable form factor improves internal cable routing and installation flexibility.
