Rackspace Cloud Files vs. Amazon S3 vs. Azure

As usual, when the support of a new cloud storage service provider is added to the Gladinet platform, we will do basic speed test against supported service providers to see how they compare to each other.

This time we will compare Rackspace Cloud Files with Amazon S3 and Windows Azure Blob Storage.

The Test

Gladinet Cloud Desktop is used for the test. Cloud Files, Amazon S3 and Azure storage accounts are mounted into Windows Explorer as virtual folders.

The test is simple, From Windows Explorer, a 28M file is drag and dropped into each service provider’s virtual folder. A stop watch is used to time the duration it takes each to complete transfer (upload).

After that, the Gladinet Cloud Desktop cache is cleared. The same 28M file is drag and dropped from the cloud storage virtual folder into local folder. The transfer (download) time is also captured.

The Result

Service Providers Upload Time (Sec) Download Time (Sec)
Rackspace Cloud Files 194 37
Amazon S3 East 204 34
Amazon S3 West 203 45
Windows Azure Blob 197 76

The upload speed is around 150 KBytes/sec for Rackspace transfer. The download speed is around 800KBytes/sec.

As a reference point, here is a bandwidth test with the Internet connection. The pipe to the Internet has decent speed to conduct this test.

Conclusion

It looks like Rackspace compares head to head with Amazon S3. when Rackspace has the fastest upload time, S3 East has the fastest download time.
