Azure page blobs pricing

Rest-based blobs for storing index-based and sparse data structures

Page Blobs are optimized for random read and write options. Page Blobs are ideal for scenarios that require the ability to overwrite a random small segment at a known address, like storing index-based and sparse data structures. Page blobs can be accessed through REST protocol or attached to a VM to support disk traffic as Unmanaged Disks.

For Page Blobs, you will be billed on an hourly basis.

Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month fall on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the upcoming month. Sign in to the Azure pricing calculator to see pricing based on your current program/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

General Purpose v2 provides access to the latest Azure storage features, including Cool and Archive storage, with pricing optimized for the lowest GB storage prices. These accounts provide access to Block Blobs, Page Blobs, Files, and Queues.

Premium Page Blobs

Premium Page Blobs are high-performance solid-state drive (SSD)-based storage, designed to support I/O-intensive workloads with significantly high throughput and low latency. Premium Page Blobs provide provisioned disk performance up to 7,500 IOPS and 250MBps per blob.

You can attach Premium Page Blobs to VM sizes with the “s” denomination for Premium Unmanaged Disk support—for example, Dsv1, Dsv2, and Gs. It is also recommended to use Managed Disks for VM persistent Storage for higher availability.

Pricing for Premium Page Blobs depends on:

  • Size of disks provisioned.
  • Data redundancy.
Page Blob Types Size Price per month IOPS per Page Blob Throughput per Page Blob
P10 128 GB $- $- 500 100 MB/second
P20 512 GB $- $- 2,300 150 MB/second
P30 1 TB $- $- 5,000 200 MB/second
P40 2 TB $- $- 7,500 250 MB/second
P50 4 TB $- $- 7,500 250 MB/second
P60 8 TB $- $- 7,500 250 MB/second

There are no transaction costs for Premium Page Blobs.

Your Premium Page Blob is charged based on the lowest type that supports your target size.

Azure does not support attaching P60 as a disk to VMs at this time. P60 are only supported as Page Blobs accessible through REST.

We also support three additional page blob types that require you to deploy with Blob Tier set explicitly. If you deploy the page blob or unmanaged disks only specifying the target size, it will be rounded up to the supported page blob types listed in the table above.

Page Blob Types Size Price per month IOPS per Page Blob Throughput per Page Blob
P4 32 GB $- $- 120 25 MB/second
P6 64 GB $- $- 240 50 MB/second
P15 256 GB $- $- 1,100 125 MB/second
Note: Snapshots are charged at $-/GB per month.

Standard Page Blob

Standard Page Blobs use hard disk drive (HDD)-based storage media. They are best suited for development, testing, and other infrequently accessed workloads that are less sensitive to performance variability. Standard page blobs are billed on used size and with each transaction. When deleting files within the file system backed by a page blob, some operating systems may not clear the data after deletion and you may still be charged for the previously used capacity.

Prices for Standard Page Blobs depend on:

  • Volume of data stored per month.
  • Quantity and types of operations performed, plus outbound data transfer cost.
  • Data redundancy.

Data transfer for Disks and Page Blobs

When you write data into GRS accounts, that data will be replicated to another Azure region. The Geo-Replication Data Transfer charge is for the bandwidth of replicating that data to another Azure region. This charge also applies when you change the account replication setting from LRS to GRS or RA-GRS.

Operations for Page Blobs used as Unmanaged Disks

We charge $- per 10,000 transactions for Standard Page Blobs attached to VM and used as Unmanaged Disks. Any type of operation against Unmanaged Disks is counted as a transaction including reads, writes, and deletes.

Operations for Page Blobs (Non-disks)

Page Blob transactions that are not performed through a VM are billed on a per-transaction basis. For each transaction, a single operation is billed as either a write, a read, or a delete operation. If a read or write transaction is larger than 64 KB, an additional read or write input/output (IO) is billed for each additional 64 KB, up to a maximum of 15 IOs per transaction. If the transaction is larger than 1 MB [64 KB x (1 transaction + 15 IOs)], no further IOs will be charged, regardless of the size of the transaction.
