　　DB300 is a SD to SATA Bridge LSI which is compliant with the latest SD Standard 3.0 (SDXC & UHS-I) and
　　SATA Standard 2.6 (1.5Gbps: Gen1).
　　It simply converts high speed (Up to UHS-1) and high capacity (up to 2TB) SD card to SATA storage device and enables
　　high speed data transfer without any special SD Software driver.
　　DB300 executes SD card and SATA Host initialization quickly and autonomously, so that it will be also used as program storage to
　　boot products like conventional SATA I/F HDD or SSD.
　　DB300 has dual SD Host controllers, so that it enables to build RAID/JBOD and Dual Storage operation.
　　In Dual Storage mode, build in SD-DMA function can transfer data between 2 SD cards without any CPU interruption.
