  • Block blobs are comprised of blocks, each of which is identified by a block ID.

    You create or modify a block blob by uploading a set of blocks and committing them by their block IDs.

    If you are uploading a block blob that is no more than 64 MB in size, you can also upload it in its entirety with a single Put Blob operation. -Each block can be a maximum of 4 MB in size. The maximum size for a block blob in version 2009-09-19 is 200 GB, or up to 50,000 blocks.

    Page blobs are a collection of pages. A page is a range of data that is identified by its offset from the start of the blob. To create a page blob, you initialize the page blob by calling Put Blob and specifying its maximum size.

    -The maximum size for a page blob is 1 TB. A page written to a page blob may be up to 1 TB in size.

    what to use block blobs for: streaming video. “The application must provide random read/write access” which is supported by Page Blobs
