Make sure your computer is running in AHCI mode

The first step in optimizing SSD is to ensure that your disk read and write mode is AHCI, but for today’s computer systems, they are basically windows7 or windows10 systems. You only need to install the system normally, and the disk settings will be automatically selected as " AHCI", but if your computer system is older or you mistakenly select IDE and other modes when installing the system, you don’t need to worry, just do the following steps:

1. Click win+R to enter the run dialog box.

2. Enter Regedit to enter the registry.

3. Select the path "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci".

4. Right-click to modify the disk mode to "0" and restart it.


Turn on the TRIM function

TRIM is a very important function, it can improve the read and write ability of SSD and reduce latency. Therefore, after installing the operating system, be sure to confirm whether the TRIM function is enabled. The user can run CMD in administrator mode and enter "fsutil behavior query DisableDeleteNotify". If the return value is 0, it means that TRIM is on; otherwise, if the return value is 1, It means that TRIM is off.

4K alignment is very important

The so-called 4K alignment actually refers to 4K advanced formatting, which requires 4K alignment of hard disk sectors. The 4K advanced formatting standard stipulates that the sector size of the hard disk is migrated from the current 512 bytes to 4096 bytes (or 4K). This change will improve formatting efficiency, which will help the hard drive provide higher capacity while providing improved error correction.

You can check the 4K alignment through the AS SSD software. If you find that your SSD does not have 4K alignment, it doesn’t matter. You can use the above software (ParagonAlignmentTool) to perform lossless 4K alignment on the SSD.

turn off the system recovery function

This is an aspect that people generally don't pay attention to when using solid state drives. However, there are feedbacks that system restore will affect the normal operation of SSD or TRIM, and then affect the read and write capabilities of SSD.

Turning off the system restore is very simple, you only need a few simple steps to complete:

1. Right click on my computer and select properties;

2. Choose system protection;

3. Setting items;

4. Turn off system restore
