The state-of-the-art and competitive eMMC delivers incredible performance at higher processing speeds for today's single-board computers. With maximum sequential read/write speeds of 250 MB/s and 180 MB/s (based on 64 GB), this tiny eMMC memory module can handle heavy workloads without a problem. The eMMC module with the round orange sticker does not have an operating system pre-installed. After attaching the eMMC module to the H2/H3, connect the USB stick with the operating system installation image to the H2/H3 and install the operating system on the eMMC.
