I know it would be relatively small but can anyone wager a guess as to how much each of the 2gb freemium packages costs Dropbox? At 50 million users it has to add up--I've always wondered about Dropbox's conversion rate (free to pay) but it must be relatively high to support the current monetary system.

Keep in mind that they use S3, so they pay for what they use, not what they have committed to their free users. But if they were, then for 50 million free users:

2gb * 50,000,000 = 100PB. That would qualify them for S3's over 5PB pricing of $0.055 per GB-month. So that's $66 million per year just for storage.

But again... they're probably actually using far, far less than 100PB on their free customers.

Dropbox also uses deduplication thus reducing those figures
