Why use Switch ISO torrent downloads when there are Google Drive, MediaFire, MEGA, 1Fichier downloads?
Google Drive if working will most likely be the fastest way to download XCI and NSP (Switch ISO) files, but not long after somebody complains to Google the downloads will be taken down. There is no such problem with torrent downloads. With multiple users downloading the file from a torrent it gets split into parts that get spread and distributed among the downloading peers, and even if the original uploader disconnects from the net the torrent download will continue working. Another advantage for spreading the files via torrents is that the original uploader can hide his IP address so there is nobody to complain to.
In short, if you need to download a single game or update file it may be faster to do it from a GDrive MEGA MediaFire or 1Fichier, but if you want to get a collection of multiple games doing it via a torrent is easier and it helps others like you!
