In case you want to gather up your email archives before turning them into a topic map, Amazon S3 prices have dropped:
As you can tell from my recent post on Amazon S3 Growth for 2011, our customers are uploading new objects to Amazon S3 at an incredible rate. We continue to innovate on your behalf to drive down storage costs and pass along the resultant savings to you at every possible opportunity. We are now happy (some would even say excited) to announce another in a series of price reductions.
With this price change, all Amazon S3 standard storage customers will see a significant reduction in their storage costs. For instance, if you store 50 TB of data on average you will see a 12% reduction in your storage costs, and if you store 500 TB of data on average you will see a 13.5% reduction in your storage costs.
I must confess disappointment that there was no change in the “Next 4000 TB” rate but I suppose I can keep some of my email archives locally. 😉
Other cloud storage options/rates?
