If not I apologise. The latest atom boards come with 16-64 GB emmc onboard. Apparently emmc may? perform wear levelling, SD would not unless you pay a fortune for a special SD card. There seems to be a lot of misinformation in this area which is quite dangerous considering what some of these devices may be used for. http://eu.mouser.com/new/Swissbit/swissbit-industrial-SD-memory/ There are special embedded filesystems (often pay for) that do wear leveling for standard SD, not sure if they reserve 20% of the space. I am fairly sure even emmc does not reserve 20% like sandforce/SSD does and so a full filesytem could fail quickly. Perhaps an unused partition could solve that??
