Which Virtual machine size allow for connecting Premium SSD disks
Premium SSD Managed DisksPremium SSD Managed Disks 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 SSD Managed Disks, you can provision a persistent disk and configure its size and performance characteristics. Show The total cost of Premium SSD Managed Disks 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. You choose the option that best meets your required storage size, IOPS, and throughput. Attach several persistent disks to a VM and you can configure up to PBs of storage per VM, and achieve 80,000 input/output operations per second, and 1,600 MB per second disk throughput per VM at less than one millisecond latency for read operations (for applications which can take advantage of read caching). Premium SSD Managed Disks are supported by DS-series, DSv2-series, FS-series, and GS-series VM sizes which are specifically targeted for Premium SSD Managed Disks. When using Azure Shared Disks on Premium SSD Managed Disks, each additional mount of the managed disk is charged per month based on the disk size. SnapshotsYou 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 ￥0.3/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 ￥2.353/GB per month. You can store incremental snapshots for Premium SSDs only on Standard storage. They are charged at ￥0.3/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. BurstingFor 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￥250.086 to enable on-demand bursting and a burst transaction fee of￥0.05088 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. Besides, Azure Managed Disk Reservation helps you lower your disk storage cost by committing to one-year of Premium SSD Managed Disk 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.
Managed disks are only available for Locally Redundant Storage (LRS). Please refer to Azure Storage replication page for more details on redundancy options. Standard SSD Managed DisksStandard SSD Managed Disks, a low-cost SSD offering, are optimized for test and entry-level production workloads requiring consistent latency. Standard SSD Managed Disks can also be used for big data workloads that require high throughput. Standard SSD Managed Disks deliver lower latency compared to Standard HDDs, while improving reliability and scalability for your applications, and are available with all Azure VM sizes. Standard SSD Managed Disks can be easily upgraded to Premium SSD Managed Disks for more demanding and latency-sensitive enterprise workloads. Offered as a managed disk solution, Standard SSD Managed Disks come with the same industry leading durability and availability that you expect from Premium SSD Managed Disks. The total cost of Standard SSD Managed Disk storage depends on the size and number of disks, the number of transactions, and the number of outbound data transfers. When using Azure shared disks on Standard SSDs, each additional mount of disk is charged per month based on the disk size. SnapshotYou 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 ￥0.3/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 ￥1.221/GB per month. You can store incremental snapshots for Premium SSDs only on Standard storage. They are charged at ￥0.3/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.
We charge ￥0.02 per 10,000 transaction units for Standard SSD Managed Disks. Any type of operation against the storage is counted as a transaction, including reads, writes and deletes. We use IO unit size of 256 KiB for counting the billable transaction units. Please refer to Standard SSD documentation for more information. Standard HDD Managed DisksStandard HDD Managed Disks use Hard Disk Drive (HDD) based Storage media. They are best suited for dev/test and other infrequent access workloads that are less sensitive to performance variability. The total cost of Standard HDD Managed Disk storage depends on the size and number of disks, the number of transactions, and the number of outbound data transfers. SnapshotsFull snapshots and images are charged at ￥0.3/GB per month for both LRS and ZRS snapshot 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. Incremental snapshots for Standard HDDs are charged at ￥0.3/GB per month for both LRS and ZRS snapshot options based on 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.
Ultra DiskUltra 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 pagefor more details on redundancy options. The following table summarizes the different configurations supported for different disk sizes:
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. Managed disks are only available for Locally Redundant Storage (LRS).

Which virtual machines can support premium storage?Premium Storage supports VM disks that can be attached to specific size-series VMs. Premium Storage supports DS-series, DSv2-series, GS-series, Ls-series, Fs-series, and Esv3-series VMs.
What is the maximum size of single disk supported for virtual machine?The maximum size for a virtual hard disk is 2,040 gigabytes (GB). However, any virtual hard disk attached to the IDE controller cannot exceed 127 gigabytes (GB). To support a larger virtual hard disk size, attach the virtual hard disk to a SCSI adapter.
What is the difference between standard and premium SSD?Premium SSDs offer greater performance and durability when compared to standard SSDs due to their higher NAND flash capacity and faster read and write speeds. PRO TIP: Standard SSD and premium SSD offer different levels of performance, with premium SSD offering higher levels of throughput, IOPS, and latency.
What are standard SSD sizes?The standard form factor for an SSD is 2.5-inch, which fits inside the drive bay of most laptop or desktop computers. Because many users replace their hard drives with solid state drives, the 2.5-inch drive has become a standard for all HDDs and SSDs.
