How to calculate the lifespan of SSD solid-state drives and what factors affect their lifespan

Date:January 2nd,2024 View:38
The lifespan of solid-state drives has always been a controversial topic in the industry. Due to the limitations of erasure and write times in solid-state drive flash memory, many people criticize its short lifespan. Many users feel frustrated that their purchased solid-state drives break down after a short period of use. But in fact, this kind of suppression is unnecessary. By the time the lifespan of solid-state drives expires, I believe the entire computer has been completely phased out. So what is the lifespan of solid-state drives? How to calculate? Next, Seten will share how to calculate the lifespan of SSD solid-state drives. Although these are theoretical values, they are for reference only. Even if it reaches its lifespan, it may not necessarily deteriorate< Br/>

The lifespan of solid-state drives is mainly determined by the number of erasures and capacity. There is no difference in the number of erasures and writes for different capacities and particles. At present, there are four types of solid-state drives on the market: SLC, MLC, TLC, and QLC. At present, SLC particles have a high cost, small capacity, and are relatively rare. Most MLC products are positioned as high-end products. TLC is currently the mainstream particle in the market, while QLC particles have the shortest lifespan but lower cost and larger capacity< Br/>

The theoretical erasure frequency of SLC particles is above 100000 times p/e, MLC particles are around 3000-5000 times p/e, TLC particles are between 1000-3000 times p/e, QLC particles are within the range of 1000-3000 times p/e, and particle theoretical erasure frequency is only 150 times p/e, with p/e as the unit of lifespan< Br/>

SSD solid-state drive lifespan calculation method

The formula for P/E lifespan (number of erasures * capacity/daily erasure/365)

The formula for P/E lifespan is erasure times * capacity/daily erasure amount/365. Assuming a 256GB TLC granular solid-state drive, based on the daily erasure amount of 100GB, its lifespan is 1000 * 256/100/365, which is about 7 years. The maximum number of writes is also theoretical. If it exceeds this limit, it will break down by 100%. The key is that the computer cannot be turned on every day, and there are also rest periods. In addition, it cannot erase 100GB every day< Br/>
