Solid State Drives (SSDs) are gaining particular momentum in various frameworks such as multimedia, large data centers and cloud environments. Unfortunately, efficient CAD tools for SSD design space exploration able to assess the optimization of the device microarchitecture w.r.t. the target performance are still missing. This paper tries to close this gap by proposing SSDExplorer, a tool for fine-grained and fast design space exploration of SSD devices. SSDExplorer provides unprecedented insights into the architecture behavior and subcomponent interaction efficiency, while avoiding the need for the actual implementation of an FTL or of key hardware components. This is achieved by the introduction of suitable abstractions of the different components. This is confirmed by the thorough validation of SSDExplorer against a commercial SSD device
