Seedboxes on high speed networks are typically able to download large files within minutes, provided that the swarm can actually handle such a high upload bandwidth. Seedboxes generally have download and upload speeds of 100 megabits per second. This means that a 1
GB file can finish downloading in under 2 minutes. That same 1 gigabyte file can be uploaded to other users in the same amount of time, creating a 1:1 upload:download ratio for that individual file. The ability of a seedbox to transfer files so quickly is a big attraction seedboxes hold within the
P2P and BitTorrent communities.
Because of the mentioned high speeds, seedboxes tend to be extremely popular inside private torrent trackers, where maintaining an upload/download ratio above 1 can be very important, although this is frustrating to other users who do not have access to these types of resources and therefore struggle to maintain a good ratio.
