if atime changes, then a read operation adds a write operation which might be or not be cached. If you want to increase duration of a frail SSD, you can disable partially or completely atime (relatime, lazytime, noatime).A.B– A.B2019-06-11 18:10:10 +00:00Commented Jun 11, 2019 at 18:10

I am only interested in physical address of SSD. If atime changes frequently due to repeatedly read operation, does it cause Gargbage Collection? I think it is not efficient for inode to move to other blocks because of only read operation.YohanChoi– YohanChoi2019-06-12 03:57:46 +00:00Commented Jun 12, 2019 at 3:57

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
