Study: SSD Lifespan Boosted by 43%

Laurie Wired highlighted a South Korean study showing that adjusting peak voltage and pulse length during NAND erase cycles increased the lifespan of standard Samsung 3D TLC NAND by **43%**. The article notes that "erasing" degrades SSDs far more than "writing." The core idea replaces the traditional multi-round fixed-pulse erase process with a conservative "predict + incremental pulse" strategy. This not only extends lifespan but also improves the **p99.99 tail read latency** by roughly **22%**.
