I found this answer about Heroku free plan disk space
[Heroku Bandwidth and Space](https://stackoverflow.com/questions/5530216/heroku-bandwidth-and-space).
But this is in 2011, I dont know if it's still accurate so far.

Besides that, this Heroku Support's response on this post
[Heroku free account limited?](https://stackoverflow.com/questions/4536326/heroku-free-account-limited) (the second answer) made me confused too.
Does that mean the free plan disk space is up to 1GB.

Can anyone help me with this, any response will be so appreciated.
