Network-wise, I got the usual Rackspace throttling-induced asymmetry - 194Mb/s going from the 1GB instance to the 15GB, 874Mb/s the other way. Likewise, the cloud block storage significantly underperformed the instance storage at just under 8K IOPS - though that's still really nothing to sneeze at in a public cloud.
For something you can rent by the hour these are pretty sweet. It's not too hard to find 10KIOPS-capable machines elsewhere for much less, but then again those IOPS might not do you much good if the machines are network-constrained (and many of the cheaper providers do tend to be). As always, measure for yourself. It's always good to see that bar being raised.
What region were you running the tests in and when did you conduct your testing? We very recently made some networking changes that should have dramatically improved the cloud block storage IOPS capabilities.
Thanks for your time and don't hesitate to reach out if you have any questions, comments or concerns.
Thanks!

It goes on to note how performance is important and invites clients to "contact a Racker to talk about your performance objectives.". The words "server" and "SSD" don't even appear in it. Well, at least he didn't invite us to "dialogue".
But anyway, seems to be all SSD now, but no longer resizable machines. Some more technical notes here: http://www.rackspace.com/knowledge_center/article/what-is-ne...
All the more reason to go with Digital Ocean, I guess.
In the performance tests we've run since the networking changes, we've seen substantially better IOPS performance with Cloud Block Storage. If you happen to rerun your tests we'd love to hear about the results!
Thanks for checking our products out.
