external concrete disk will never slow ur computer it is used by USB connection where on earth data verbs will be 11MB per minutes,
An external hard drive slows down the computer. What will slow it down is how your transmitting notes to that hard drive. Having more memory would speed it up because then you hold resources devoted to other processes while that is performing.
