LDE (Long-term Data Endurance) - an industry metric, introduced by SanDisk,that quantifies how much data can be written to an SSD in its lifespan expressedin terabytes written (TBW). Data is written using typical PC transfer sizepareto, written at a constant rate over the life of the SSD, and data isretained for at least 1 year upon LDE exhaustion.
