SSD Lifespan (TBW & DWPD)
Estimate how many years an SSD will last from its TBW rating and your daily writes, and convert TBW to DWPD, free online.
À propos de cette calculatrice
The endurance rating TBW (terabytes written) is the total data the SSD is warrantied to absorb. Lifespan = TBW ÷ (daily writes × 365). DWPD (drive writes per day) = TBW ÷ (capacity × warranty years × 365). Typical consumers write 10–40 GB/day, so a 600 TBW drive lasts decades.
