In einer Untersuchung der Nasuni Corporation wurden verschiedene Anbieter von Cloud Storage wie Microsoft, Amazon, HP, Rackspace oder Google verglichen.
Microsoft consistently performed better than the other CSPs in the tests, delivering the best Write/Read/Delete speeds across a variety of file sizes, the fastest response times and the fewest errors. Not only did Microsoft outperform the competition significantly during the raw performance tests, it was the only cloud storage platform to post zero errors during 100 million reads and writes. In those categories where Microsoft was not the top performer (uptime and scalability variance), it was a close second.
For these reasons, Microsoft has replaced Amazon to achieve the top performer position in the 2013 report. Cloud storage is a rapidly evolving market with new providers and new offerings entering all the time.Nasuni, A Benchmark Comparison of Performance, Availability and Scalability
