You can estimate your drive's theoretical lifespan in years by using the metric provided in its datasheet.
Remaining 150 TB of writes / 150 TB per year = 1 year left. ssd life expectancy calculator
| Use Case | Daily Writes | 500 GB TLC SSD (300 TBW) | 1 TB QLC SSD (400 TBW) | |----------|--------------|--------------------------|-------------------------| | Light (web, docs) | 15 GB | ~56 years | ~75 years | | Moderate (gaming, photo editing) | 40 GB | ~21 years | ~28 years | | Heavy (video editing, VMs) | 100 GB | ~8.4 years | ~11.2 years | You can estimate your drive's theoretical lifespan in
This is defined by . Every time you write or rewrite data, you consume a portion of this finite budget. Once the budget runs out, the drive enters a read-only mode or fails entirely. Every time you write or rewrite data, you
If you have a 1TB SSD with a 600 TBW rating and you write roughly 20GB (0.02 TB) of data per day: Key Metrics Explained
If your calculator says your drive has less than 5% health remaining , you are in the "danger zone." Immediately back up and replace the drive. Do not wait for 0%.
600 ÷ (30 × 365 ÷ 1024) = 600 ÷ 10.7 ≈ (theoretical, but other failures may occur first).
