I’m delving into the specifics of Zoned Namespace (ZNS) SSDs and am curious about the fundamental reasons behind structuring these drives using namespaces. Particularly, I’m wondering why the concept of namespaces is integral to the design of ZNS SSDs.

For example, I’m interested in practical applications where a zone size of 2MB or 2GB is utilized. What specific needs or benefits do these smaller zone sizes address? Are there particular applications or use cases where having 2MB or 2GB zones, managed through namespaces, significantly impacts performance or efficiency?

Understanding these aspects will help me better grasp the architectural choices behind ZNS and their practical implications in real-world applications.

Thank you for your insights!
