Amazon EC2 now powered by high performance storage (benchmark)

A while ago I had a discussion with someone about the future of server infrastructure. Among other things, we were wondering whether companies will continue to run on dedicated servers or if eventually everyone just ends up in a Cloud environment. During the discussion I raised a point that in principle Cloud is a great idea that will keep attracting more and more people, but it is missing one important piece that stops many from using it - a high performance storage. Apparently, this has just changed.

Later I thought maybe polishing information a little bit and publishing a step-by-step walkthrough on the blog may help a few people. So here it is.

It is understandable that one can never get very reliable results on EC2, this is a shared environment after all, and that some fluctuations should be expected, however it is still good to know the numbers. I started my benchmarks and everything seemed fine at first, but then sometimes statistics I was getting started looking quite odd.
