If you are looking to understand the differences between Premium Page Blob vs Standard, read along.
Azure Storage, a cloud-oriented storage solution offered by Microsoft, provides two distinct types of storage accounts: Premium Page Blob and Standard Blob Storage. While both types offer secure and scalable data storage, they vary in terms of performance, scalability, and ideal use cases. This article aims to compare these two types of Azure Storage accounts comprehensively.

Premium Page Blob Storage: An Overview
Premium Page Blob storage is specifically designed for applications that work with smaller kilobyte-range objects and require high transaction rates or consistent low-latency storage. It’s fine-tuned for read/write operations and is typically employed to support an unmanaged disk for an Azure virtual machine. However, Microsoft advises using managed disks with Azure virtual machines where possible.
The scalability targets for Premium Page Blob storage accounts include:
- Disk capacity: 4 TB (individual disk)/ 35 TB (cumulative total of all disks)
- Snapshot capacity: 10 TB
- Total bandwidth for a locally redundant storage account: Up to 50 gigabits per second for both inbound and outbound
If your application surpasses these scalability targets, Microsoft suggests migrating to managed disks. If migration isn’t feasible, you should design your application to utilize multiple storage accounts and distribute your data across those storage accounts.
Standard Blob Storage: An Overview
Standard Blob Storage accounts, encompassing general-purpose v2 (GPv2), general-purpose v1 (GPv1), and Blob storage accounts, are versatile storage solutions suitable for a broad range of scenarios. Microsoft recommends using a GPv2 storage account for most use cases.
The scalability targets for Standard Blob Storage accounts include:
- Maximum number of storage accounts with standard endpoints per region per subscription: 250 by default, 500 upon request
- Default maximum storage account capacity: 5 PiB
- Default maximum request rate per storage account: 20,000 requests per second
- Default maximum ingress per general-purpose v2 and Blob storage account in specific regions: 60 Gbps
- Default maximum egress for general-purpose v2 and Blob storage accounts in specific regions: 120 Gbps
Comparative Table: Premium Page Blob vs Standard
Feature/Parameter | Premium Page Blob Storage | Standard Blob Storage |
---|---|---|
Optimization | Fine-tuned for read/write operations | Versatile, suitable for a broad range of scenarios |
Use Case | Supports an unmanaged disk for an Azure virtual machine | General-purpose storage, recommended for most scenarios |
Disk Capacity | 4 TB (individual disk)/ 35 TB (cumulative total of all disks) | Not specifically mentioned |
Snapshot Capacity | 10 TB | Not specifically mentioned |
Total Bandwidth | Up to 50 gigabits per second for both inbound and outbound | Varies based on region and account type, up to 120 Gbps for egress and 60 Gbps for ingress |
Storage Account Capacity | Not specifically mentioned | Default maximum is 5 PiB |
Request Rate | Not specifically mentioned | Default maximum is 20,000 requests per second |
Storage Accounts per Region per Subscription | Not specifically mentioned | Maximum of 250 by default, 500 upon request |
Recommended Disk Type | Unmanaged disks, but migration to managed disks is suggested if scalability targets are exceeded | GPv2 storage accounts are recommended for most use cases |
Conclusion
The choice between Premium Page Blob and Standard Blob Storage depends on your specific application requirements. Premium Page Blob storage accounts offer superior performance. They are ideal for read/write-intensive applications, while Standard Blob Storage accounts provide versatile storage solutions for a wide range of scenarios.
