This post says there’s a limit of 5 thousand Blob Storage requests per storage account per second.

Transactions – Up to 5,000 entities/messages/blobs per second

What exactly happens if I hit this limit?

    The request fails with an error: http://blogs.msdn.com/b/windowsazurestorage/archive/2010/07/09/understanding-windows-azure-storage-billing-bandwidth-transactions-and-capacity.aspx (search ‘Throttling’ in the page).

    Throttling – These are requests that are being throttled due to the
    transaction rate going over the per partition target throughput
    described in the post “Windows Azure Storage Abstractions and their
    Scalability Targets”. These throttled requests are counted as billable
    transactions. When this occurs, the client is expected to use
    exponential backoff and retry the request, which is provided by
    default with the storage client library. If it is a reoccurring event
    for the service, then the service should consider additional
    partitioning of its data structures as described in the upcoming posts
    on Blobs, Tables and Queues.

    The error codes you might get back from the REST API are here: http://msdn.microsoft.com/en-us/library/windowsazure/dd179382.aspx – I can’t immediately see which one would apply in a throttling context.
