A computing system (100) having a storage system that includes a storage device (130) and a host device (105), where the host device (105) is configured to issue memory access commands to the storage device (130). The computing system (100) further includes a prediction system (190) comprising processing circuitry that is configured to perform operations that cause the prediction system (190) to identify one or more components of the storage system (918) that limit random rad performance of the storage system (918). The operations further cause the prediction system (190) to obtain characterization data that is indicative of the impact of the one or more components on random read performance and generate a model based on the characterization data to predict random read performance of the storage system (918). The operations additionally cause the prediction system (190) to execute the model in a simulation of the storage system (918) to generate a random read performance parameter for the storage system (918).
