The core of Military Class 4 is based on the essentials which increase your stability in the worst conditions. The humidity protection & high temperature protection ensure your system surviving each environment, no matter how harsh. The structure of the PCB limits EMI radiation. On top of that all the connectors have ESD protection in order to prevent short circuit. Compared to common motherboards which need extra BIOS chips, MSI's M-Flash has a double advantage which doesn't need extra components & secondly, all your BIOS data will be saved in the USB (Universal Serial Bus) drive. The stored data does not only have backup & upgrade function, moreover, it can also be seen as a portable BIOS chip which is actually able to boot up your PC. Compared to the 480 Mbps provided by traditional USB (Universal Serial Bus) 2.0, the all-new USB (Universal Serial Bus) 3.0's 5 Gb/s offers 10 times the transfer bandwidth, so transferring a Blu-ray movie takes less than one minute.
