Azure Standard SSDs, now in preview, provide a low-cost managed disk solution optimized for test and entry-level production workloads requiring consistent latency.
Standard SSDs can:
- Deliver lower latency compared to Standard HDDs.
- Be used for big-data workloads that require high throughput.
- Improve reliability and scalability for your applications.
- Offer the same industry-leading durability and availability you expect from Azure Disk Storage.
- Be upgraded to Premium SSDs for more demanding and latency-sensitive workloads.
