Dear members,

I am trying to estimate the projected hard disk space usage by a web app; assuming the said web app is a school software;

If 60 students and 40 users are using 6.3 GB of hard disk space, how many GBs will 100 students and 90 users use?

Or is there a better way to estimate growth?

I am particularly at pains because students and users do not produce the same amount of data, therefore, I cant do 60+40 and use that. On the other hand, if I calculate for students kando and users kando, somehow that feels wrong because they will both use the same, well, hard disk...
