Research and Implementation of SSD Lifespan Protection Mechanism

Abstract:

With the continuous development of SSD, It becomes the commodity requirements of memory storage users especially in consumer application. NAND Flash lifespan limitation is the most concerns of every user in relation to the drive’s reliability. This paper explains three factors which embark from the basic principle effect of SSD lifespan and induced the reliability strategies/the method of SSD lifespan prediction during the SSD design and usage period. We have designed a SSD`s lifespan management software which predict and manage the SSD lifespan. It will enhance the safety of SSD usage.SSD lifespan mechanism analyzes how actively you use your solid-state drive and uses a special algorithm to calculate its estimated lifetime. Of course, the date of the lifetime expiration is corrected depending on how intensively you keep using your drive.
