I am considering using either Rackspace CloudFiles with JungleDisk or The Planet's CloudStorage for a webapp that needs fast read performance to serve very large video files.
The application uses some authentication backends that x-forward the files to be served through an nginx frontend. This setup requires that the files be stored on a mounted directory, which is what I understand JungleDisk does for Rackspace Cloudfiles and what The Planet's CloudStorage does natively.
JungleDisk is marketed mostly as a backup tool that can be used as a mounted drive, while The Planet advertises its cloudstorage as "unlimited storage" that is natively mounted as a NFS.
An old StorageCloud whitepaper makes some very bold claims about their performance being many times faster and consistently stable, but it's not really an unbiased source.
Does anyone have any experience with a similar scenario and has any insights about the subject?
Thanks!
