Amazon Grid Storage Web Services:
Move over Google Drive, Amazon just stole your thunder (for now).
Pricing is cheaper than anything else I’ve seen: $0.15 per GB of storage per month, and $0.20 for each GB of data transferred up or downstream. This translates to $15 per month for 100 GB of storage, net of any transfer fees (to move that much data on to S3 would be a one time cost of $20). These prices are going to be significantly below the development and ongoing costs for small or medium sized storage projects - meaning a lot of the front end services I’ve previously profiled will be much better off moving their entire back end to S3.
