Virtual Machine Storage

VM Storage

There are two disks:

a. Operating System Disk - Hosts OS
b. Temporary Disk - Temporary Storage like page file caching, unreliable for long term storage (d:\)

When you provision a new VM, a copy of Virtual Hard Drive image is added to your Azure Blob Storage account. Hard Drive Image is mounted to your Virtual Machine Instance.

There are two types of persistent disks, both comprised of Page Blobs (Get high availability, durability, geo-redundancy)

1. OS Disk (c:\)
2. Data Disk - Preferred Disk for Long Term Data (e:\)
