由於SSD冇mechanical movement,再加上有寫入壽命,所以話唔駛/唔好做defregmentation,今日唔覺意入Win 10個tools入面睇吓,個SSD Optimization竟然default係ON,冇理由M$唔知架,於是上網搵吓資料
搵倒以下資料,原來SSD都要做defrag,因為假如個file太散的話,散到個OS上限就會讀唔倒,所以要定期搞搞佢,但唔會好似HDD咁搬法
"Additionally, there is a maximum level of fragmentation that the file system can handle. "

最後個結論係:
Conclusion
No, Windows is not foolishly or blindly running a defrag on your SSD every night, and no, Windows defrag isn't shortening the life of your SSD unnecessarily. Modern SSDs don't work the same way that we are used to with traditional hard drives.
Yes, your SSD's file system sometimes needs a kind of defragmentation and that's handled by Windows, monthly by default, when appropriate. The intent is to maximize performance and a long life. If you disable defragmentation completely, you are taking a risk that your filesystem metadata could reach maximum fragmentation and get you potentially in trouble. |

初初以為你講緊TRIM
