Boffins from Bell Labs and Stony Brook University have put together a cloud storage system they hope can serve as a reference design for future cloud implementations. Called SEARS – Space Efficient And Reliable Storage – the research has been published at Arxiv here, and appears to rival Amazon's S3 cloud storage. The …
the point of distributed/resilient storage is NEVER speed. Speed is over-rated. Just use S3, code your task intelligently. Do your own object chunking (don't send a huge object to S3 - slice it to <=5GB yourself - https://aws.amazon.com/s3/faqs/) and let it run at the speed of data.
Write your code so that when S3 has issues (6hrs ago) your process intelligently retries or just sleeps waiting for API availability to be restored.
I bet they thrashed an internee to wake whole night tweak those 10 machines to reduced time to 2.5sec for that cherry picked 3MB file or he kept rerunning the upload untill for once he got 2.5sec even he didnt know was it because prefetch or what... secondly if AWS is taking 7sec is not because they r slower but could be marketing throttle to reduce 7sec only when competition is approaching this value. so u uni students plz snap out of for why u r called 'students' and not "professionals".
