One of my friends has a deep understanding of the benefits of aligning partitions. His work asks fast working step. Though he is a man of high operating speed, his computer always let him down and worked slow, especially when transfer data. He did try to find the reason but did not succeed. Once when we chat online, accidentally I knew that from him. Since I know what the exact reason can be, I told him the reason for the slow work of his PC and teach him how to realign partition. He did as I told him and it did work; his computer runs much faster than before. Now, he never worries about his work being affected by his computer anymore.
