Abstract: The present technology improves the operation and endurance of storage drives by adapting the amount of over-provisioning for a drive to the write profile for the particular service assigned to the drive. The amount of over-provisioning for the drive is determined based on the write profile of the service and the attributes of the drive, such as the drive's specifications and the workload history of the drive. The write profile of the service can be predicted using a model that is empirical or is based on historical data. For example, the write profile can be predicted based on the similarity of the service to services in the historical data. The actual write profile of the service can be monitored, and if it deviates from the predicted write profile the amount of over-provisioning can be dynamically adjusted based on the actual write profile.
