An uses manufacturer specifications and your personal usage patterns to estimate how many years of service remain in your drive. Core Formula for SSD Life Expectancy
When you save a 1KB text file, the SSD cannot just write 1KB. It must read an entire block (usually 4MB), modify the 1KB in cache, erase the block, and rewrite it. This multiplies the actual physical writes by 3x to 10x. If the calculator doesn't ask for your OS and workload type (database vs. media storage), it is lying.
To find the "Total Host Writes" currently on your drive, you can use specialized software:
Estimated Lifespan (years) equals the fraction with numerator TBW Rating and denominator Average Daily Writes (TB) cross 365 end-fraction TBW Rating:
One day, your system is fast; the next day, you face the dreaded "Operating System not found" error.
Need a quick number? Install CrystalDiskInfo – it literally gives you a “Remaining Life %” without any math.
All show estimated as a percentage.
