In this presentation we will discuss why KV SSD is the ultimate storage solution, and why it will replace ZNS. We will explore how KV SSD solves many of the issues with flash management and the scaling of SSD devices in storage systems. KV SSD is a contrasting direction to Zone Namespaces and the migration of flash management to the Host. We feel KV SSD is a better direction, as the axiomatic optimal solution is to perform garbage collection at a single layer in any system, and that this garbage collection is optimal when it is as close to the flash as possible.
