One difference I see is that QFS is block-based and each file is composed of multiple S3 objects. Hence, there is no file size limit.

Hi, we recently announced Quantcast File System version 1.2. Besides many bug fixes and improvements, it comes with the ability to use Amazon S3 as a backend store. You can check it out on QFS Github. I personally contributed to this release, and I'd be happy to answer any questions. Thanks.
