Announcing larger, higher scale storage accounts

One of the fastest areas of growth in cloud computing is around data storage. With a variety of workloads such as IoT telemetry, logging, media, genomics and archival driving cloud data growth, the need for scalable capacity, bandwidth, and transactions for storing and analyzing data for business insights, is more important than ever.

Up to 10x increase to Blob storage account scalability

We are excited to announce improvements in the capacity and scalability of standard Azure storage accounts, which greatly improves your experience building cloud-scale applications using Azure Storage. Effective immediately, via a request made to Azure Support, Azure Blob storage accounts or General Purpose v2 storage accounts can support the following larger limits. The defaults remain the same as before.



New Limit

Max capacity for Blob storage accounts

500 TB

5PB (10x increase)

Max TPS/IOPS for Blob storage accounts


50K (2.5x increase)

Max ingress for Blob storage accounts

5-20 Gbps (varies by region/ redundancy type)

50Gbps (up to 10x increase)

Max egress for Blob storage accounts

10-30 Gbps (varies by region/ redundancy type)

50Gbps (up to 5x increase)

These new limits apply to both new and existing Blob storage accounts and General Purpose v2 Storage accounts. You can continue to leverage all of your favorite features in these storage accounts at-scale, without any changes required. The new limits are available for all Azure clouds.

Please contact Azure Support to get your Blob storage or General Purpose v2 storage accounts raised to these new limits for storage capacity, TPS/IOPS, ingress or egress. We are also actively working to increase these numbers even further, so contact us even if your workload requires even higher capacity.

Frequently asked questions

1. Will this improve performance or reduce latency in uploading data to or retrieving data from Azure Storage?

No. This feature is a scalability improvement and does not impact latency. If you experience any performance issues with Azure Storage, please check our troubleshooting documentation or you can contact Azure Support.

2. Do the new limits apply only to Blob Storage?

The new limits specified on Blob storage accounts apply only to Blob Storage. The increase to General Purpose v2 storage accounts does, however, apply to all services at the account level. Other service-specific limits such as File share sizes and Queue TPS/IOPS will continue to apply.

3. What is a General Purpose v2 storage account? How do I convert from a General Purpose storage account to a General Purpose v2 storage account?

General-purpose v2 (GPv2) accounts are storage accounts that support all of the latest features for blobs, files, queues, and tables. GPv2 accounts support all APIs and features supported in GPv1 and Blob storage accounts. They also support the same durability, availability, scalability, and performance features in those account types. Pricing for GPv2 accounts has been designed to deliver the lowest per gigabyte prices, and industry competitive transaction prices. Please check our migration documentation for details.

4. Will I be able to apply the new limits for Disk traffic?

We recommend that you use Managed Disks since that already handles scalability of disks for your VM.
