Additional storage options
Page blobs are optimized for writes at random locations within a blob. They also support Unmanaged Disks.
Table storage provides a NoSQL Key-Value store for massive scale structured data.
Queues stores messages to be processed asynchronously.
Data redundancy options
| LRS | Designed to provide at least 99.999999999 % (11 9's) durability of objects over a given year by keeping multiple copies of your data in one datacenter. |

Migrate your data to Azure Storage
Use Azure Import/Export to send your data to Azure Storage, shipping hard drives quickly and economically.
Now available: General Purpose v2 storage account
Azure now offers three types of storage accounts: General Purpose v2, General Purpose v1, and Blob Storage. Storage accounts determine eligibility for certain storage services and features, and each is priced differently. We recommend thoroughly reviewing the pricing models to determine which is the most appropriate, as some workloads can be priced very differently depending on which account type is used.
For new customers, we generally recommend General Purpose v2 for access to the latest storage features, including Tiered Storage and Archive. We recommend General Purpose v1 and Blob Storage accounts only for customers with prior experience with those accounts, but these customers may also benefit from using GPv2. Learn more about the benefits of different storage account types .
FAQ
Expand All-
If I use Azure Storage for only a few days a month, is the cost prorated?
Yes. Storage capacity is billed in units of the average daily amount of data stored, in gigabytes (GB), over a monthly period. For example, if you consistently used 10 GB of storage for the first half of the month, and none for the second half of the month, you would be billed for your average usage of 5 GB of storage. However, using the Cool (GPv2 accounts only) or Archive tier for less than 30 and 180 days respectively will incur an additional charge.

How do I know which data redundancy option (see above) I’m using?
You can select your redundancy when creating your storage account. Once created, you can check the redundancy either by using the Azure Portal or the service management API.

We guarantee that we can successfully process data reading requests from an offsite redundant storage (RA-GRS) account at least 99.99% of the time (99.9% for the Cold Access Layer), provided that we will retry in the secondary zone from the data writing failure from the primary zone.
We guarantee that we can successfully process data reading from local redundant storage (LRS) and offsite redundant storage (GRS) accounts at least 99.9% of the time (99% for the Cold Access Layer)
We guarantee that we can successfully process data writing requests into onsite redundant storage (LRS) and geo-redundant storage (GRS) accounts and read and access geo-redundant storage (RA-GRS) accounts at least 99.9% of the time (99% for the Cold Access Layer).

The Managed Disk itself doesn’t provide a Service Level Agreement with financial support. The availability of a Managed Disk depends on the Service Level Agreement governing the basic storage used and the Virtual Machine it’s attached to.
