NATICK, USA: Only six of the 16 cloud storage providers passed the Nasuni Stress Tests, in terms of providing the minimum level of performance, stability, availability and scalability that organizations need to take advantage of cloud for primary storage, data protection and disaster recovery.

The six CSPs that passed were:
AT&T Synaptic Storage as a Service (powered by EMC Atmos)
Microsoft Windows Azure
Peer1 Hosting (powered by EMC Atmos)
Two CSPs emerged as top performers in the Nasuni study: Amazon S3 and Microsoft Windows Azure, with Amazon S3 being the standout across all evaluation areas.
Since April 2009, Nasuni has conducted ongoing tests of the 16 largest CSPs.
Though Nirvanix was 17 per cent faster than Amazon S3 for reading large files, and Microsoft Azure was 12 per cent faster when it comes to writing files, no other vendor posted the kind of consistently fast service across all file types as did Amazon S3.
Amazon S3 had the fewest outages and best uptime, and was the only CSP to post a 0.0 per cent error rate in both writing and reading objects during scalability testing. And though Microsoft Azure had a slightly faster average ping time than Amazon S3 (likely because Amazon S3 is much more heavily used than Microsoft Azure), Amazon nevertheless had the lowest variability.
