I would like a dedicated torrent box which would be the best device I have a pogoplug v2 and series 4 both running arch linux arm as well as a raspberry pi rev b?

For a dedicated torrent box, the Raspberry Pi Rev B is a solid choice due to its community support and ability to run lightweight torrent clients like Transmission or Deluge. While the Pogoplug devices can also be configured for torrenting, the Raspberry Pi offers better performance and flexibility for file management and remote access. Additionally, consider using an external USB drive for storage to maximize your torrenting experience.
