Depending on your hardware (SBC), FTP can also be several times faster than SFTP for transferring files over a LAN. Though I'll admit to having used other protocols like torrents for large files that had bad transfers or other issues (low-quality connection issues causing dropped connections, etc).

TFTP is also a good choice for transferring files over trusted networks to/from underpowered devices.
