TBW, is a 硬盘工作量单位, used to define 界定保修范围. That is, if 硬盘的工作量the hard disk exceeds this value, the manufacturer may refuse to insure it.
Question 1, why was there no concept of TBW before?
- In the past, mechanical disks did not worry about bad writing, so there was no need for this concept.
- Most solid-state disks are MLC particles, which have a very long lifespan, almost the same as those without.
- Nowadays, the lifespan of the hard drive is really a concern. (If you use a disk to move a large amount of data every day, write failure is inevitable)
Question 2, what impact does TBW value have on users?
If the combined daily disk usage exceeds 5G, you should pay more attention to this value rather than the warranty period. Especially designers, audio and video processing workers, and workers who browse a large number of web pages to search for information.
Question 3, how to calculate TBW?
Calculation formula: 150TBW=150x1024GB=153600GB. Simply speaking, the total workload allowed by the disk is 150T
