What disk type should be set for the OS disk while creating a new Azure virtual machine as per the provided configuration?

The recommended disk type for the OS disk when creating a new Azure virtual machine typically depends on the intended performance requirements and the use case of the virtual machine. In general, Standard HDDs are a cost-effective solution for workloads that do not require high input/output operations per second (IOPS) and where performance is less critical. This type of disk uses traditional hard drive technology, making it suitable for applications that are not sensitive to latency or performance, such as web servers, development environments, and other applications with lower performance demands.

Standard SSDs offer better performance compared to Standard HDDs and are suitable for a broader range of applications. Premium SSDs, meanwhile, are designed for I/O-intensive applications that require high throughput and low latency, often used with more demanding workloads. Ultra Disks are tailored for scenarios that require extreme performance, offering high IOPS and throughput for mission-critical applications.

Choosing Standard HDD for the OS disk might be appropriate if the configuration is meant for simple workloads with budget constraints, but for many use cases, SSD options are often recommended for their improved performance characteristics. However, if the selection is primarily driven by cost or the nature of the applications running on the VM, then using Standard HDD could be justified in specific scenarios.
