Disk Drives in Microsoft Azure

In this article, we will discuss disk drives in Microsoft Azure. But before we move forward, let us discuss some of the important concepts.

Hard Disk Drive (HDD) Vs. Solid State Drive (SSD)

HDD is the traditional storage disk drive that uses a mechanical platter for moving read and write head in order to access data.

SSD is the new type of storage device that uses flash memory to access the data faster.

Data Tier

Data tier means, storing the data on different tiers based on its accessibility. There are three different types of access tiers

      1. Hot tier - Data which is frequently accessed.

      2. Cold tier - Data which is less frequently accessed and stored for at least 30 days.

      3. Archive tier - Data which is rarely accessed and stored for at least 180 days.

Different storage type

In Azure, there are different storage types

      1. Standard HDD

      2. Standard SSD

      3. Premium SSD

Premium SSD is the most expensive storage. Here is the table with different parameters.
