Why each option
For production and performance-sensitive workloads in Azure, Premium SSDs are generally recommended as a cost-effective solution offering high performance.
Ultra Disks offer the highest performance with configurable IOPS and throughput, but they are typically overkill and significantly more expensive for most general production and performance-sensitive workloads where Premium SSDs suffice.
Premium SSDs are designed for I/O-intensive production workloads, offering high throughput and low latency, making them suitable for performance-sensitive applications like databases and enterprise applications. While Ultra Disks offer even higher performance, Premium SSDs provide an excellent balance of cost and performance for most production scenarios.
Standard SSDs offer consistent performance but are generally recommended for web servers, lightly used enterprise applications, and dev/test environments, not for heavily performance-sensitive production workloads.
Standard HDDs are ideal for backup, non-critical data, and infrequent access, offering the lowest cost but significantly lower performance than SSDs, making them unsuitable for production and performance-sensitive workloads.
