Very detailed results. It's interesting how poorly digital ocean did for consistency of IO. Amazon, Rackspace and Softlayer seemed to fare best in many categories ahead of Azure, GCE, digital ocean etc. GCE database IO performance seemed particularly poor. Amazon seems to be far ahead of the rest for internal network throughput and latency.

GCE no longer offers a local storage option, this is one reason slower IO. They also cap IOPS for better IO consistency.
