If I was going to use two separate hard drives with one faster than the other, for example hard drive A > hard drive B, which should be used for reading and which for writing to? Basically both are traditional technology platter drives, and one will be storing the raw unencoded file, and the other will be the destination drive. I am basically wondering if all other things are equal, and not considering cpu, memory, etc, where the faster drive should be for optimal encoding time. Does anyone know if reading the raw file or writing the encoded file is more hard drive intensive? Would it be dependent on file size, e.g. would a 6gb raw file being transcoded to a 2gb file be more drive intensive on the reading end simply because it is a bigger file with more information? And vice versa?
