I've conducted some independent tests of various block storage options with Rackspace, EC2, HP and GCE. Here are links providing a CSV of the results (may take a few seconds to generate). A value of 100 signifies near performance parity to a baremetal SAS reference system. Overall, Rackspace SSD is performant, but lacks the consistency of EBS PIOPs or GCE persistent storage.
