Construct a solid-state drive aging dataset based on storage speed and read speed; S3. Repeat steps S1 to S2 for multiple SSDs of the same model, and merge the aging data sets of all SSDs to obtain an aging test training set. S4 constructs a classifier model through a neural network, and trains the constructed classifier model using the aging test training set obtained in step S3 to obtain an aging test model; S5. For SSDs with unknown aging levels, test the storage speed vector and the read speed vector, and use the test sample features consisting of the superposition of the storage speed and the read speed as input to the aging test model, which then outputs the aging level.
