Abstract

Systems and methods for increasing the endurance of a solid state drive are disclosed. The disclosed systems and methods can assign different levels of error protection to a plurality of blocks of the solid state drive. The disclosed methods can provide a plurality of error correction mechanisms, each having a plurality of corresponding error correction levels and associate a first plurality of blocks of the solid state drive with a first zone and a second plurality of blocks of the solid state drive with a second zone. The disclosed methods can assign a first error correction mechanism and a first corresponding error correction level to the first zone and can assign a second error correction mechanism and a second corresponding error correction level to the second zone.
