Deluge Forum

I have Deluge directly downloading to a USB drive which has a write speed of 75 MB/s. The download is crawling at K/s. It does write much faster if I transfer directly to a drive on my PC but I would rather use the USB. How can I increase the speed of the download from Deluge to USB drive?

Hello DelugeGuy,

Have you experimented this with a different drive and also with a different filesystem? For example with a thumbdrive, but with different filesystems to see if it does make a difference.

I ran into something similar once, and the first thing I'd check is whether the daemon is actually running and if there are any errors in the logs. If this started after an update, it can also help to test with a fresh config or temporarily disable any plugins to rule out a bad setting. That usually narrows it down pretty quickly.

USB drives have overhead from the USB protocol, and bittorent sends pieces, sometimes many peices depending on the torrent and how its made, and they arent necessarily consecutive. This creates a situation where your USB drive is not only recieving loads of signals to write all over the place, but that same packet traffic over USB is clogged at 75MB/s when if you shucked the drive and placed it in a SATAIII connection it would likely do well over 200MB/s reads/writes.

This is just a consequence of the protocol USB and hard drives themselves writing unconsecutively.
