The option to increase data transfer while not increasing hardware specs.
in my case, my application runs on my home server 24/7 checking, running, managing, downloading etc. So for people like me its ideal to have 1cpu and 512 mb of ram but that hardware spec with higher data transfer would be ideal.
e.g. a 512mb droplet with 8tb of transfer. I understand this would be an increase in price but not as much as the 8tb droplet.
