When it comes to moving massive files between storage clouds, performance depends — quite a bit — on which clouds you use, according to new research. For its report Bulk Data Migration in the Cloud, Nasuni repeatedly transferred 12 TB of data between its top-rated clouds–Amazon’s (s amzn) S3, Microsoft Windows Azure (s msft) and Rackspace (s rax).
This was not an academic exercise for Nasuni because it manages customers’ encrypted data on these clouds and often transfers the data from cloud to cloud for optimum performance or redundancy. But the findings are broadly applicable to the many companies that are considering cloud storage options. Once they put their data in a given cloud, they want assurances that they’ll be able to move it as needs dictate. Surprisingly, Nasuni found the time it takes to transfer data varies considerably depending on which cloud is on the receiving end of that data.
Here are the top-line findings for moving 12TB of data from one cloud to another:
