Premium SSD
Premium SSDs are high-performance Solid-State Drive (SSD) based Storage designed to support I/O intensive workloads with significantly high throughput and low latency. With Premium SSDs, you can provision a persistent disk and configure its size and performance characteristics.
The total cost of Premium SSDs depends on the size and number of the disks, and will be affected by the number of outbound data transfers. These disk sizes provide different input/output operations per sec (IOPS), throughput caps, and monthly price per GiB. Premium SSDs are supported on various virtual machine sizes and options, including DS-series, DSv2-series, FS-series, and GS-series - to run your workloads. Premium SSDs support both locally-redundant storage (LRS) and zone-redundant storage (ZRS) options. Please refer to Azure Storage replication page for more details on redundancy options. Premium SSDs with ZRS are currently generally available in select regions with more regional availability to come. To see ZRS pricing, please select ZRS as a redundancy option in the drop-down. When using Azure shared disks on Premium SSDs, each additional mount of disk is charged per month based on the disk size. Shared disk pricing is the same for either LRS or ZRS option.
Snapshots
You can store full snapshots and images for Premium SSDs on Standard storage. You can choose between locally redundant (LRS) and zone redundant (ZRS) snapshot options. These snapshots and images are charged at $-/GB per month for both Standard LRS and ZRS options based on the used portion of the disk. For example, if you create a snapshot of a managed disk with provisioned capacity of 64 GB and actual used data size of 10 GB, snapshot will be billed only for the used data size of 10 GB. If you choose to store them on Premium SSDs Managed Disk storage, you’ll be charged at $-/GB per month.

You can store incremental snapshots for Premium SSDs only on Standard storage. They are charged at $-/GB per month for both Standard LRS and ZRS snapshot options of the storage occupied by the delta changes since the last snapshot. For example, you are using a managed disk with provisioned size of 128 GB and used size of 100 GB. The first incremental snapshot is billed only for the used size of 100 GB. 20 GB of data is added on the disk before you created the second snapshot. Now, the second incremental snapshot is billed for only 20 GB.
Azure confidential VMs offer a new and enhanced opt-in disk encryption scheme called confidential disk encryption. This scheme protects all critical partitions of the disk. It also binds disk encryption keys to the virtual machine's TPM and makes the protected disk content accessible only to the VM. More information on confidential OS disk encryption can be found here - Confidential OS Disk Encryption. This encryption scheme carries a charge in addition to the disk price.

|---|---|---|
| Premium SSD Managed Disks | LRS | $- |
| Premium SSD Managed Disks | ZRS | $- |
Bursting
For P20 disks and smaller, credit-based bursting is enabled by default with no additional costs. You can boost your performance up to 3,500 IOPS and 170 MB/s for up to 30 min to handle spiky traffic, process batch jobs, and improve boot times.
For P30 disks and larger, you will be charged a monthly enablement fee of $- to enable on-demand bursting and a burst transaction fee of $- per 10,000 IOs for additional IOPS. You can boost your performance up to 30,000 IOPS and 1,000 MB/s at any point in time. For example, if you provision a P30 disk with 5,000 IOPS and you burst to 30,000 IOPS for 5 seconds, you will be charged an enablement fee to enable the bursting feature as well as a burst transaction fee for the additional 25,000 X 5 = 125,000 IOs. If you burst your throughput above the provisioned amount, you will also be charged a burst transaction fee for the additional throughput. For detailed examples on how the billing works, refer to this article.
Reservation
Azure Disk Storage reservations help you lower your disk storage cost by committing to one-year of Premium SSD capacity. Reserved capacity can be purchased in increments of 1 disk unit for 1-year commitment duration. All prices are per month. For more information, please see Azure Disks FAQ.

125-1,200
(Increases by 0.25 MB/s per set IOPS) |
Snapshots
You can store incremental snapshots for Premium SSD v2 only on Standard storage. They are charged at $-/GB per month for both Standard LRS and ZRS snapshot options of the storage occupied by the delta changes since the last snapshot. For example, you are using a managed disk with provisioned size of 128 GB and a used size of 10 GB. The first incremental snapshot is billed only for the used size of 10 GB. Before you create the second snapshot, 20 GB of data is added to the disk. Now, the second incremental snapshot is billed for only 20 GB.
Pricing
The total cost of Premium SSD v2 Disk Storage will depend on the size and number of disks you provision and their configurations.
Premium SSD v2 disks will be billed hourly and provide different disk sizes with a configurable range of input/output operations per second (IOPS) and throughput measured in MB/s. You can choose the configuration that best meets your workload requirements in terms of storage capacity, IOPS, and throughput. Disk storage capacity, IOPS, and throughput will be charged separately.

Standard SSD
Standard SSDs, a low-cost SSD offering, are optimized for test and entry-level production workloads requiring consistent latency. Standard SSDs can also be used for big data workloads that require high throughput. Standard SSDs deliver lower latency compared to Standard HDDs, while improving reliability and scalability for your applications, and are available with all Azure VM sizes. Standard SSDs can be easily upgraded to Premium SSDs for more demanding and latency-sensitive enterprise workloads. Standard SSDs come with the same industry leading durability and availability that you expect from Premium SSDs.
The total cost of Standard SSDs storage depends on the size and number of disks, the number of transactions, and the number of outbound data transfers. Standard SSDs support both locally-redundant storage (LRS) and zone-redundant storage (ZRS) options. Please refer to Azure Storage replication page for more details on redundancy options. Standard SSDs with ZRS are currently generally available in select regions with more regional availability to come. When using Azure shared disks on Standard SSDs, each additional mount of disk is charged per month based on the disk size. Shared disk pricing is the same for either LRS or ZRS option.
Snapshots
You can store full snapshots and images for Standard SSDs on Standard HDD storage. You can choose between locally-redundant (LRS) and zone redundant (ZRS) snapshot options. These snapshots and images are charged at $-/GB per month for both Standard LRS and ZRS options based on the used portion of the disk. For example, if you create a snapshot of a managed disk with provisioned capacity of 128 GB and actual used data size of 10 GB, snapshot will be billed only for the used data size of 10 GB. If you choose to store them on SSD storage, you’ll be charged at $-/GB per month.

Ultra Disk
Ultra Disk is our next generation high performance Solid State Drive (SSD) with configurable performance attributes that provides the lowest latency and consistent high IOPS/throughput. Ultra Disk offers unprecedented and extremely scalable performance with sub-millisecond latency. As a customer you can start small on IOPS and throughput and adjust your performance as your workload becomes more IO intensive.
The total cost of Ultra Disk depends on the size of the disk and its performance configuration and will be affected by the number of disks.
Ultra Disk is available in different sizes that provide a configurable range of input/output operations per sec (IOPS), and a configurable range of throughput (MB/s), and is billed on an hourly rate. You choose the option that best meets your required storage size, IOPS, and throughput. Ultra Disk only supports locally redundant storage (LRS). Please refer to Azure Storage replication page for more details on redundancy options.
Please refer to the Ultra Disk documentation page for the full details on how to configure the disks.
| Ultra Disk Configuration | Unit | Hourly Price | Monthly Price** |
|---|---|---|---|
| Disk Capacity (GiB) | GiB | $- | $- |
| Provisioned IOPS | IOPS | $- | $- |
| Provisioned Throughput (MB/s) | MBps | $- | $- |
| Provisioned vcpu reservation charge* | vCPU | $- | $- |
Ultra Disk is billed based on the provisioned size, provisioned IOPS and provisioned throughput. Azure maps the provisioned size (rounded up) to the nearest disk size offer. Each disk is billed accordingly on an hourly basis. For example, if you provisioned a 200 GiB Ultra Disk, with 20,000 IOPS and 1,000 MB/second and deleted it after 20 hours, it will map to the disk size offer of 256 GiB and you'll be billed for the 256 GiB, 20,000 IOPS and 1,000 MB/second for 20 hours. This is regardless of the amount of actual data and number of IOs written to the disk.
There is no charge per mount for shared Ultra Disks. You are charged for the capacity and total IOPS and throughput on the disk. For more details, refer to the shared disk documentation.
Ultra Disk only supports locally redundant storage (LRS). Please refer to Azure Storage replication page for more details on redundancy options.
Snapshots
You can store incremental snapshots for Ultra Disk only on Standard storage. They are charged at $-/GB per month for both Standard LRS and ZRS snapshot options of the storage occupied by the delta changes since the last snapshot. For example, you are using a managed disk with provisioned size of 128 GB and a used size of 10 GB. The first incremental snapshot is billed only for the used size of 10 GB. Before you create the second snapshot, 20 GB of data is added to the disk. Now, the second incremental snapshot is billed for only 20 GB.

Frequently asked questions
-
You will be charged the same rate for your provisioned disk, regardless of how much of the disk space is being used.
-
The charges will be pro-rated on an hourly basis using the monthly price. For instance, Premium SSD for P15 is $- (price may vary per region). For October, you will be billed per $-/(31 days x 24 hours) = $-/hour
-
Ultra Disk is billed based on the provisioned size, provisioned IOPS and provisioned throughput.
-
The total cost of Premium SSD v2 Disk Storage depends on the size and number of disks you provision, and their respective configurations in terms of provisioned IOPS and throughput.
For example, if you have an application that requires three different disks with the following characteristics:
- Disk 1 - 64 GiBs, 2,000 IOPS and 120 MB/s of throughput
- Disk 2 - 256 GiBs, 4,000 IOPS and 100 MB/s of throughput
- Disk 3 - 1,024 GiBs, 15,000 IOPS and 1,200 MB/s of throughput
The monthly cost for each Premium SSD v2 Disk, in a Locally Redundant Storage (LRS) configuration, in the East US region will be:
- Disk 1 monthly cost = 64*$0.081 = $5.14/month
- Disk 2 monthly cost = 256*$0.081 + (4,000-3,000) * $0.0052 = $25.67/month
- Disk 3 monthly cost = 1,024*$0.081 + (15,000-3,000) * $0.0052 + (1,200 – 125) * $0.041 = $186.71/month
Prices are subject to change depending on the region you choose.
-
The total monthly price of a Standard SSD disk has two components:
(a) the storage cost associated with the disk size and
(b) a variable component that depends on the number of transactions per hour that are taking place during the month.For example, if you select a 4 GiBs E1 Standard SSD SKU, with locally redundant storage (LRS), and perform an average of 4,000 transactions per hour, your total price will be
(a) $- / month + (b) 4,000 transactions per hour * ($-/10,000 transactions) * 730 hours per each month = $- + $- = $- / month.
Note: 730 hours per month is calculated by dividing the total number of hours in a year 24 hours * 365 days divided by 12 months = 730 hours in a month.
Conversely, if you selected the same disk size, with locally redundant storage (LRS), and your workload performed 8,000 transactions per hour, your total price will be (a) $- / month + (b) $- = $- / month.
In other words, the additional 8,000 – 6,800 = 1,200 transactions per hour would be offered at no additional charge.

The system starts billing newly created empty Premium SSD, Standard SSD and Standard HDD disks when they are attached to a VM for the first time to save your cost.
