If an SSD vendor uses DWPD as a measurement, calculate endurance in TBW with the following equation: TBW (over 5 years) = Drive Size x DWPD x 365 x 5. For example, consider an SSD which can take 1,000 TB of writes over its 5-year lifetime. Throughout the SSD market, SSD vendors rate drive reliability on three factors: Age of the drive; Total terabytes written over time (TBW) Drive writes per day (DWPD) Of the three, only the age of the drive is a precise measurement. Bottom Line: The ADATA SE800 external SSD is everything you want in a shirt-pocket solid-state drive: sleek, tough, affordable, and snappy. Chertow GM, Lazarus JM, Lew NL, Ma L, Lowrie EG calles as Chertow Formula (TBW-C).
