Azure Premium SSD v2 Key Features and Performance Benefits

Azure Premium SSD v2 offers a massive 7,500 IOPS (input/output operations per second) for low-latency and high-throughput performance. This is a significant boost from its predecessor, making it ideal for demanding workloads.

With its high IOPS, Azure Premium SSD v2 can handle a large number of concurrent requests, ensuring that your applications stay responsive and performant. This is especially important for businesses that rely on fast data access to stay competitive.

Azure Premium SSD v2 also features a 2,000 MB/s throughput, allowing for fast data transfer and large-scale applications. This makes it an excellent choice for data-intensive workloads such as scientific simulations, data analytics, and machine learning.

Azure Premium SSD v2 offers a granular disc size of 1 GiB, allowing for precise storage capacity provisioning up to 64 TiB.

You can provision storage capacity in increments of 1 GiB, making it easy to scale up or down as needed.

With a baseline performance of 3,000 IOPS and 125 MB/sec, Premium SSD v2 discs offer consistent latency of under a millisecond.

This means that your applications can perform at their best, even during peak hours.

Here are some key features of Azure Premium SSD v2 at a glance:

One of the benefits of Premium SSD v2 is that it allows for easier maintenance with no downtime while scaling performance up and down.

This is a major advantage over other storage solutions, where scaling up or down can often require downtime.

Azure Premium SSD v2 also offers data durability and high availability, just like other Azure Disk Storage products.

Azure Premium SSD v2 disks offer flexible performance configuration, allowing you to independently set IOPS and throughput to meet your workload needs.

You can adjust the performance of a Premium SSD v2 disk four times within a 24 hour period, with creating a disk counting as one of these times. This means you can only adjust its performance up to three times in the first 24 hours after creating a premium SSD v2 disk.

The performance configuration model of Azure Premium SSD v2 disks is flexible, allowing you to individually set the capacity, throughput, and IOPS of a disk. This flexibility provides you with more options and reduced costs.

Here are the performance configurations for Premium SSD v2 disks:

Ultra Disks, on the other hand, have a fixed maximum IOPS of 400,000 IOPS per disk and a throughput limit of 10,000 MB/s per disk.

Performance is a crucial aspect of any cloud storage solution, and Azure's Ultra Disk and Premium SSD v2 offerings are no exception. Ultra Disks are designed to provide low sub millisecond latencies and provisioned IOPS and throughput 99.99% of the time.

Ultra Disks support IOPS limits of 300 IOPS/GiB, up to a maximum of 400,000 IOPS per disk. To achieve the target IOPS for the disk, ensure that the selected disk IOPS are less than the VM IOPS limit.

The throughput limit of a single Ultra Disk is 256-kB/s for each provisioned IOPS, up to a maximum of 10,000 MB/s per disk. The minimum guaranteed throughput per disk is 4kB/s for each provisioned IOPS, with an overall baseline minimum of 1 MB/s.

You can adjust Ultra Disk IOPS and throughput performance at runtime without detaching the disk from the virtual machine. After a performance resize operation has been issued on a disk, it can take up to an hour for the change to take effect.

You can adjust the performance of a Premium SSD v2 disk four times within a 24 hour period. Creating a disk counts as one of these times, so for the first 24 hours after creating a premium SSD v2 disk you can only adjust its performance up to three times.

Here's a comparison of the IOPS limits for Ultra Disks and Premium SSD v2 disks:

All Premium SSD v2 disks have a baseline IOPS of 3000 that is free of charge. After 6 GiB, the maximum IOPS a disk can have increases at a rate of 500 per GiB, up to 80,000 IOPS.

Ultra Disks and Premium SSD v2 disks both offer flexible performance configuration models, allowing you to independently configure IOPS and throughput before and after provisioning the disk.

Capacities range from 1 GiB to 64 TiBs in 1-GiB increments, with billing based on a per GiB ratio as seen on the pricing page.

You can have up to 100 TiB per region per subscription by default.

Premium SSD v2 offers a flexible capacity option that supports higher capacity by request.

To request an increase in capacity, you can either request a quota increase or contact Azure Support directly.

You can save money on Azure Premium SSD v2 by purchasing a disk reservation, which provides a discount on the advance purchase of one year's worth of disk storage.

Azure Disks Reservation offers a one year commitment plan for Premium SSD SKUs from P30 (1 TiB) to P80 (32 TiB) in all production regions.

You can bundle VM and Disk reservations to maximize your savings.

Here's a breakdown of the pricing for Azure Premium SSD v2:

Azure Pricing can be a bit complex, but let's break it down.

Managed disk size is billed on the provisioned size, so you'll pay for what you've allocated, not what you're using.

For Azure Premium SSD v2, you'll be charged for the provisioned capacity, which is 200 GiB in our example.

Any additional IOPS provisioned over the baseline free limit of 3,000 IOPS will be invoiced, so if you've allocated 6,000 IOPS, you'll be billed for the extra 3,000.

Throughput above the basic free throughput of 125 MB/s is also invoiced, so if you've provisioned 175 MB/s, you'll be billed for the additional 50 MB/s.

Snapshots are charged based on the size used, so if you've taken a snapshot that's 100 GiB, you'll be charged for that amount.

Outbound data transfers incur billing for bandwidth usage, so be mindful of how much data you're transferring out of Azure.

You're charged for the number of transactions you perform on a managed disk, which includes read and write data operations.

Here's a quick summary of the pricing factors for Azure Premium SSD v2:

Keep in mind that these are just some of the pricing factors to consider when using Azure, and there may be other costs involved depending on your specific use case.

Azure Reservation offers a discount on advance purchases of one year's worth of disk storage, reducing your total cost.

You can select a specific disk SKU in a target region, such as five P30 (1 TiB) Premium SSDs in the Central US region for a one year term.

The disk reservation experience is similar to Azure reserved VM instances, allowing you to bundle VM and Disk reservations to maximize your savings.

Azure Disks Reservation currently offers a one year commitment plan for Premium SSD SKUs from P30 (1 TiB) to P80 (32 TiB) in all production regions.
