The differences are very-well documented on msdn, [here](https://msdn.microsoft.com/en-us/library/azure/ee691964.aspx). TL;DR:

- *Block* blobs are for your discrete storage objects like jpg's, log files, etc. that you'd typically view as a file in your local OS. Max. size 200GB 4.77TB. Regular (non-Premium) storage only.

- *Page* blobs are for random read/write storage, such as VHD's (in fact, page blobs are what's used for Azure Virtual Machine disks). Max. size 8TB. Supported by both regular and Premium Storage.

Note: Premium page blobs have specific sizings (unlike regular page blobs, which can be any size up to 8TB).

- 32GB

- 64GB

- 128GB

- 512GB

- 1024GB

- 2048GB

- 4096GB

Premium storage provides guaranteed IOPS and throughput, depending on the page blob size chosen (from 120 IOPS+25MB/s @ 32GB to 7500 IOPS+250MB/s @ 2048GB & 4096GB). Specific details around IOPS+throughput details are documented [here](https://learn.microsoft.com/en-us/azure/storage/storage-premium-storage).
