I. Maintenance, Optimization and Precautions of Solid State Hard Disk
1, don't "defragment" SSD with disk utility.
2. Don't use performance testing tools too much.
3. It is very important to turn on Trim.
The role of Trim is to optimize SSD reasonably and reduce the speed of its performance degradation. There are many ways to open trim online, so I won't introduce them. The way to check whether your system is enabled with trim is: enter fsutil behavior in command line mode to query DisableDelete Tenotify, and DisableDeleteNotify = 0 means enabled.
4. Choose a high-performance power mode for the notebook computer.
Energy saving not only saves electricity, but also saves performance, especially for solid state drives. Start-Control Panel-Hardware and Sound-Power Options, change the default "Balance" to "High Performance".
5. Necessary 4K calibration
From the screenshot, yours has been calibrated at 4K.
6. Select AHCI mode.
AHCI mode is turned on in SATA option of motherboard BIOS.
Second, the operating system
Disable some boot programs. Use optimization tools to streamline the operating system and delete infrequently used software.
You are a solid state drive or MLC NAND flash memory, and the theoretical number of erases is 3000, which means that your life span is very long, but I don't know how long you said "before". If you use it for a long time or write frequently, the performance will definitely decline.
