A petabyte of memory?! That's a lot of RAM. I think you mean disk space. 20mb per post would be absurd for a social network. Is every single post a super high res image?
I think some of your assumptions are incorrect, but let's take a look at some of the costs for this kind of thing on amazon's cloud (competitive pricing)
Disk space costs:
27,000gb * (.11 per gb storage (Amazon s3)) == $2,970 per month
Bandwidth costs:
27,000gb * (approx .11 per gb outbound bandwidth (Amazon s3)) == $2,970 per month
Looking at close to 6k a month in costs before you even get in computational time for serving the files.
For a social network w/ 400 users, that would mean each user would have to be worth $15 per month minimum, just to cover costs. Facebook is lucky if it can make $0.15 per user per month.
Facbook makes around a billion a year I think.
1,000,000,000 / 12 months = 83,333,333.33 per month / 800,000,000 users = approx 10 cents per user per month
In short, I think you're vastly overestimating the needs of that site.
