NVME IS NOT A HARD DISK

Summary from the TLDR Dev newsletter

NVMe (nonvolatile memory express) is a storage access and transport protocol for flash and next-generation solid-state drives that delivers high throughput and fast response times for all types of enterprise workloads. NVME over fabric over TCP allows you to make storage available even if it is in the wrong box. Distributed storage may be complicated, but it has a number of very attractive use cases.
