Symptoms
Cause
A download writes every piece it receives to disk. Seeding reads data from disk: each piece a peer requests is read from disk, so a torrent that uploads to many peers reads all the time.
Rtorrent 16 also writes its own files. rtorrent saves its session every 15 minutes, and the watchdog writes a few log lines every five minutes. By default, both are kept on the volume where Rtorrent 16 is installed.
A few settings add disk activity, and their defaults keep it low (step 2).

- The NAS disks are busy or audible while torrents run, also when they only seed.
- The disks never go quiet, even at night.

Resolution
- See how busy the disk is. On the Dashboard, the Performance card draws Disk response time for the volume the running downloads write to, with the Utilization of its busiest disk.
- Check the disk settings. Open Settings → Files & storage and turn on Advanced at the top. Under Disk I/O, pre-allocate files and re-hash on completion should be off, and Preload pieces before uploading should read Read into memory.
- Keep the package's own files on a less busy disk. On the same page, Where logs, settings and temporary files are kept and Where rtorrent keeps its session read With the package by default: the volume where Rtorrent 16 is installed. When Rtorrent 16 is installed on an SSD beside spinning data disks, this keeps the writes off the data disks. To use another folder, pick A directory I choose and its folder. Press Review & save and confirm. rtorrent stops while the files move and starts again.
- Pause torrents at night. Open Settings → Date & time, turn on Night mode, set the hours and pick Pause every torrent as the Night action.
Notice & Advise
- Less upload means fewer reads: a lower upload limit or fewer seeding torrents.
- With Copy as the Action for completed downloads, each finished download is written a second time. The default, Hardlink: the same data, no extra space (a copy across volumes), writes nothing new on the same volume.
