BLOB Storage is the main type of storage that Microsoft use and promote. Bellow you will find the different types of BLOB storage and use cases. This will help you find the best storage solution for your business needs.
BLOB Storage is broken into 3 separate types of storage Hot, Cool and Archive (which we discussed in an earlier blog). This is further broken down into 3 sub categories Block, Append and Page BLOBs. This allows for even more flexibility when choosing the right storage type for your business.
Block BLOB Storage – Is a general use case BLOB that focuses on functionality and large file transfers. With Block BLOBs you can replace, delete, and insert data with ease, upload files in parallel to reduce upload time, due to the increased size, less write operations are needed when manipulating the data. You can have up to 4.75TB of total Block BLOB storage and up to 256MB per Block.
Page BLOB Storage – Is optimised for random read and write operations.
Maximum size is 8TB per Page BLOB and up to 4MB per BLOB. Due to the ability to over efficiently overwrite and immediately commit the data, it is the storage architecture that is used for VHDs.
Append BLOB Storage – Is optimised for append operations.
Like Block BLOB when you add or change data in the BLOB it will only add the data at the end of the BLOB but Append BLOBs won’t expose the Block ID when editing any data on the BLOB. With Append BLOBs you can have 195GB of data in a BLOB and up to 4MB of data in a Block.
Unless your business has strong rules about security or would like the responsiveness of the Page BLOBs, then we would usually recommend the Block BLOB Storage due to the large Block sizes and its focus on efficiently handling of large amounts of data at a cost-effective price point.
