Wear-Leveling extends SSD lifespan, and improves reliability. The more storage cells on a SSD, the longer it will work. For instance, having more storage capacity ensures a much longer lifespan of an SSD. The number of write cycles, and capacity of the drive differs depending on the model. Using a wear-leveling technique, data becomes distributed across all storage cells. Wear-Leveling functions allows all blocks to ensure a supreme lifespan.
