### 4. Functionality

Operating Principle:
The DOM‑0064M‑40H‑030 emulates a standard IDE hard disk using NAND flash memory managed by an internal DSP‑based controller. The controller handles wear leveling, ECC, and defect block management transparently to the host. Data is stored in 512‑byte sectors and transferred via the IDE bus using standard ATA commands.

Use Cases & Applications:
- Embedded industrial controllers and PLCs
- Data acquisition and measurement systems
- Telecommunications equipment and routers
- Kiosks, POS terminals, and ticket machines
- Military and avionics computers
- Transportation and vehicle systems
- Set‑top boxes and network appliances
- Legacy PCs and industrial motherboards requiring IDE storage

Compatibility:
Fully compatible with any system supporting 40‑pin IDE (ATA) interface. Recognized by BIOS as a standard HDD. Supports all major operating systems without additional drivers.
