- 3.1 %
- Ratings are measured with standard JEDEC workloads (JESD218/219); small random writes wear drives faster than large sequential ones.
- Reaching the rating does not mean immediate failure, but the warranty ends there. Monitor SMART “percentage used”.

英語の技術説明
Ratings follow JEDEC workloads; your write amplification may differ. Reaching the rating ends the warranty rather than the drive. Everything is calculated in your browser; nothing is sent or probed on the network.
TBW = DWPD × capacity × 365 × years. Life = TBW ÷ (daily writes × extra write amplification × 365).
A 1.92 TB drive rated 1 DWPD for 5 years = 3,504 TBW; writing 300 GB a day uses it up in 32 years.
