As SSD flash memory MLC turns to TLC and QLC, not only write performance is getting lower and lower, but also life and reliability are attracting more and more attention. There are always netizens who worry that SSD will be written dead, so write life is very important. < / P > < p > TBW refers to the megabytes written by terabyte writer, or total bytes written. It refers to the total amount of data that can be written to SSD before the end of SSD service life, which is used to express the life index of SSD. < / P > < p > TBW is a very important indicator of SSD, which represents the life cycle of SSD. In the case of the same amount of writing, the data of SSD with larger TBW will be more secure. < / P > < p > in addition, Zhiti technology also helped you to calculate the number of years of daily use of SSD. They said that consumer SSD will write 5-6gb a day, 170tbw can be used for 80 years for ordinary consumers, and even PC users, OEM users, enterprise users and other users with high demand can support them for more than 10 years. < / P > < p > according to Zhiti’s algorithm, the service life of 80 years is really long enough. If you buy an SSD hard disk, you may not be able to write the SSD hard disk until someone is gone. However, the algorithm of 80 years is too simple to consider such factors as write amplification. But Zhiti is right to say that it takes more than 10 years, and the service life of more than 100tbw is really long enough. < / P > < p > the reason why the life of 170tbw is calculated is that the 256gb SSD can provide 170tbw life at least, and the 1TB SSD can provide 680tbw life at most. Google said the proposed media negotiation rules would put its free services in Australia at “risk”
