I know that the maximum slug size allowed is 200 MB. But what is the maximum disk space you can use per instance? Say I'm downloading a couple of files when the node process is running.

The maximum slug size has been increased to 200MB: devcenter.heroku.com/changelog-items/72 and devcenter.heroku.com/articles/slug-compiler#slug-size. –  matt Aug 23 '12 at 20:34
Reflected that above. –  Gautham Badhrinathan Aug 23 '12 at 22:45

heroku run bash
~ $ df -h /tmp
Filesystem            Size  Used Avail Use% Mounted on
-                     620G  6.1G  583G   2% /tmp

You have approximately 620Gb in the /tmp folder.
Any other folder doesn't really matter, as they're readonly anyway.

Will I be able to use the entire 620GB given that it's a shared stack? –  Gautham Badhrinathan Jun 11 '13 at 13:29
Yes. The tmp folder is yours only. –  Damien MATHIEU Aug 7 '13 at 9:43
