As you know, torrents are an extremely effective way to distribute data to a large audience. Often times, we need to download Linux distros in a hurry, and the FTP and HTTP mirrors simply aren't fast enough. Interestingly, when we trace a download session of uTorrent, there is a significant amount of reads. This actually makes a lot of sense considering the program has to check and verify portions of the download as it connects to additional peers within the Torrent network. Moreover, a large percentage of accesses occur randomly, since torrents are downloaded in scattered bits and pieces.
