### 4. Functionality

Operational Overview:
The EMPS-3201-W1-A71 functions as a bridge between a system’s Mini PCI Express slot and two SATA III storage devices. It translates the PCIe signals into SATA protocol, enabling direct connection of SATA-based storage drives such as SSDs or HDDs.

How It Works:
1. The module is inserted into a standard mPCIe slot on the host system.
2. The onboard controller converts PCIe signals into SATA III signals.
3. Two SATA connectors on the module allow direct connection to SATA drives.
4. The host system recognizes the connected drives via AHCI, enabling native OS-level support without additional drivers.

Use Cases and Applications:
- Industrial PCs and Embedded Systems: Expands storage capabilities in compact embedded platforms.
- Network Appliances: Adds high-speed storage for caching, logging, or data buffering.
- Digital Signage and Kiosks: Provides reliable storage expansion for multimedia content.
- Automation and Control Systems: Enables local data logging and high-speed data access.
- Edge Computing Devices: Supports local storage for AI inference or data preprocessing.
- Rugged and Outdoor Systems: Wide-temperature version ensures stable operation in extreme environments.

Compatibility:
- Compatible with any system supporting Mini PCI Express 2.0 interface.
- Works with major operating systems supporting AHCI (Windows, Linux, and embedded OS variants).
- Backward compatible with SATA II and SATA I devices.
