Flash Endurance & SSD Wear Leveling Algorithms

  Although SLC NAND Flash memory provides a high level of performance, it still has a finite lifespan. There are only so many times a program and erase cycle can occur before a failure takes place and data is put at risk. To ensure that SLC memory lasts for as long as possible, SSDs rely on wear leveling algorithms. These algorithms ensure that writes are evenly distributed throughout the SSD so that blocks do not wear out prematurely. To further...
