How to open TRIM under SSD SSD under Win10?

What is TRIM? How to open TRIM of SSD solid state drive?

The TRIM of the SSD can prevent the SSD from using the useless data as useful data during garbage collection, thus extending the life of the SSD. In the HDD mechanical hard disk, the logical position of the deleted file is marked so that the data can be directly overwritten at the logical position of the useless data when the data is stored later. However, SSD solid state drives do not have this mechanism, and the master does not know that the data is useless until new data is required to be written to the block. This will result in useless data being treated as useful data in the garbage collection (GC) process, which will undoubtedly greatly reduce the efficiency and service life of the hard disk. Therefore, the emergence of TRIM can make up for the shortcomings of this problem.

First, how to check whether TRIM is enabled in Win10

You only need one command to view The steps are as follows:

1. Right click on the start button and run as administrator. “Command prompt”

2. Execute the following command: fsutil behavior query disabledeletenotify
< Br>

3. If the return value is “0” prove that TRIM is already enabled; if the return value is “1”, the current computer's SSD has not yet turned on TRIM.

Second, how to open TRIM of SSD solid state drive?

The method is not difficult, the specific method is as follows:

1, right click on the start button, run as administrator "Command prompt" & rdquo;

2, execute The following command: fsutil behavior set disabledeletenotify 0

Similarly, if you want to disable this function, just execute: fsutil behavior set disabledeletenotify 1

The above method is also applicable to Win7/Win8. 1 system. However, not all SSDs support this feature. Some vendors can extend the life of SSDs in other ways. For example, by adding a load balancing algorithm to the flash blocks that are no longer used, the SSD can be prevented from slowing down and extending after long-term use. Flash memory life, the process is completely done inside the solid state drive. Any hard disk that supports TRIM is required to support the firmware of the SSD itself, not just the operating system.
