I've never heard spoken about this tool before... but you say all that it's a awesome tool, so, I must try it.
So, if I've understood well, it works like a Low Level Format for a HDD ? But in case of the Raphael, the memory doesn't need to be formated to improve the performances. Format an USB drive does improve its performances ?
