product description SD card has the characteristics of small size, large capacity, shock and moisture resistance, high temperature resistance, stable performance, permanent and effective data storage, no noise, and no seek errors. It is a popular mainstream product memory card today. This adapter card allows you to use the SD card with this advantage to connect to the standard ATA IDE interface as a standard IDE storage device. Product Specifications: A standard IDE 3.5' interface; A standard SD socket; A standard large 4Pin power connector. Instructions for SD-IDE conversion interface board Connection Instructions: 1. The POWER power supply socket can be powered by a hard disk. The card only needs to be powered by 5V, and the normal working voltage is 5V±0.25V. The working current is less than 200mA. 2. For IDE socket, please use 80 PIN hard disk cable. This card supports PIO, Multi-word DMA and Ultra DMA Host data transfer modes; 3. SD socket supports up to 128GB SD card. After connecting the power supply and IDE cable, after inserting the SD card into the SD socket, the conversion board is equivalent to an electronic hard disk, and no driver needs to be installed. After installing the operating system, the operating system (such as windows98, etc.) can be started via the SD memory card. The data transfer rate is high, roughly the same speed as the system hard disk (ATA/133, U-DMA mode3). Package Includes : 1 x SD to 3.5" IDE Adapter
