IDE is compatible with ATA33/66/100. SD supports high-speed cards. SD cards feature a compact size, large capacity, shock resistance, moisture resistance, high-temperature tolerance, stable performance, reliable long-term data storage, silent operation, and no seek errors. Compatible with DOS, Windows CE, Windows 98/XP/Vista/NT, Windows 7/8/10, and Linux operating systems. Application areas include industrial computer motherboards, industrial computers, tablet computers, instrumentation, soft routing, POS terminals, and hard disk video recorders. Main features: 1. Uses FC1307A controller solution. 2. Supports flexible plug-and-play for SD cards in industrial environments, enabling use of the SD card as a removable storage device. 3. After installation, the SD card can be used as a system boot drive or a data storage drive. 4. Supports SD cards up to 128GB capacity. 5. Supports mechanical slot integration — a dedicated opening on the device chassis can be designed to align with the SD card slot for external access. 6. Works with standard BIOS and operating systems to support SATA and SD hot-swap functionality, plug-and-play operation, and driver-free usage. When performing hot-swap operations, ensure compatibility between BIOS, OS, and applications. Avoid hot-plugging during active read/write operations to prevent data loss. Cold swapping is recommended for optimal data integrity. 7. Form factor matches standard 2.5-inch hard drives and is compatible with legacy notebooks featuring IDE 44-pin interfaces to enhance storage performance. Precautions: ① Before use, insert the SD card into the designated SD socket, then connect both the SATA power and data cables to the host device. Upon power-on, an LED indicator will flash, confirming normal SD card data access. ② After initial setup or any SD card replacement, initialization and formatting are required before data operations can begin.
