James Serra describes a new tier of Azure Blob Storage:
As a follow-up to my blog Azure Archive Blob Storage, Microsoft has released another storage tier called Azure Premium Blob Storage (announcement). It is in private preview in US East 2, US Central and US West regions.
This is a performance tier in Azure Blob Storage, complimenting the existing Hot, Cool, and Archive tiers. Data in Premium Blob Storage is stored on solid-state drives, which are known for lower latency and higher transactional rates compared to traditional hard drives.
It is ideal for workloads that require very fast access time such as interactive video editing, static web content, and online transactions. It also works well for workloads that perform many relatively small transactions, such as capturing telemetry data, message passing, and data transformation.
It’s in private preview for now, but my guess is that it’ll be available to the general public soon enough.
