How to optimize solid state hard disk in Win7 system

The specific method is as follows:

First, AHCI hard disk mode can improve the performance of the hard disk, make sure your SSD is running in AHCI mode, open "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesmsahci". Right-click to modify the disk mode to “0”, restart, as shown below:

Modify the registry to open AHCI mode

Second, open the Trim function to reduce disk erasing operations, extend the solid state disk FLASH life, Windows 7 default state Trim command is enabled, if you want to query the current Trim command status, we can enter the command prompt interface under administrator privileges, enter "lds; fsutil behavior QUERY DisableDeleteNotify", and then you will get Feedback on related query status. Here, the prompt is "DisableDeleteNotify = 0” that is, the Trim command is enabled; the prompt is "DisableDeleteNotify = 1"; that is, the Trim command is not enabled, and the Trim command is not enabled, please update the driver and system patch in time.

Third, turn off the system recovery function, this function will affect the normal operation of SSD or TRIM, which will affect the SSD read and write capabilities.

V. Turn off the defragmentation plan, which will increase the disk read and write operations. The SSD will not generate disk fragmentation. This function will only increase the number of reads and writes.

Sixth, close the disk paging, it is not recommended that less than 4G memory to close this support, but closing the disk paging will save 3-5G disk space.

Seven, shut down the system hibernation, for solid state drives, the read speed is very fast, no need, can save 3GB of disk space.

The method is to enter the start running command dialog box, then enter the following command in the CMD command box, and then press Enter to confirm.

VIII. Turn off Prefetch and Superfetch. The 0.1ms delay is completely unnecessary. So performance will improve after shutdown. Find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManager Memory ManagementPrefetchParameters Right click on EnablePrefetcher and EnableSuperfetch to modify these data from (1 or 3) to 0 and then restart.

IX. Quick Start System This function is to close the screen when the system enters, which can save you 2-3s startup time. Other options do not move, which may have a negative impact. Press the keyboard win+R to enter Msconfig, check if no GUI boot is checked, if not, check it.
