Microsoft today announced general availability of Microsoft Azure Premium Storage. Premium Storage disk performance is achieved with a combination of durable Azure storage and server SSD caches made available to DS series VMs. You can optionally attach several premium storage disks to a single VM, and support up to 32 TB of disk storage per Virtual Machine and drive more than 64,000 IOPS per VM at less than 1 millisecond latency for read operations.
With the introduction of Premium Storage, Microsoft Azure now offers two types of durable storage: Premium Storage and Standard Storage. Premium Storage stores data on the latest technology Solid State Drives (SSDs) whereas Standard Storage stores data on Hard Disk Drives (HDDs). Premium Storage is designed for Azure Virtual Machine workloads which require consistent high IO performance and low latency in order to host IO intensive workloads like OLTP, Big Data, and Data Warehousing on platforms like SQL Server, MongoDB, Cassandra, and others. With Premium Storage, more customers will be able to lift-and-shift demanding enterprise applications to the cloud.
