A machine-learning aging framework samples real workloads in a simulator, builds lightweight per-block regression models from observed internal SSD activity, and iteratively predicts and injects future block states back into the simulator; testing uses FTLsim on a 256GB SSD with three real workloads and shows predicted wear distributions that match the fully simulated distribution while giving about 33% acceleration versus full simulation; compares against DVS and CML baselines, is modular for integration with Amber and FEMU, and explores the accuracy–efficiency tradeoff.
