You can always try torrents. Torrents are downloaded from place like this: Pirate Bay, iso hunt, kickass torrents, etc. You need u torrent (or any other torrent download thingy.) But There are two options magnet or download it and choose with your torrent downloader. By the way your download is affected by the amount of seeders and lechers, Seeders make the download faster while lechers slow it down. The more seeders the better. Hope this helps.
