After determining that SSD is the cause of stagnation, we can generally start with energy-saving compatibility. If it is an Intel motherboard, we need to check whether the Intel RST driver is currently installed. Just open the AS SSD benchmark software without running the test. The driver may have caused the traffic jam.
After installing the Intel RST driver, LPM will be turned on by default to save energy, which will reduce the power consumption when the hard disk is idle. However, due to the compatibility problems between the motherboard, solid state disk, operating system and driver, it may lead to jamming. Some jams are slight, and will recover after a period of time, and some jams will last until the shutdown and restart.
Solution:
1. Turn off link power management in Intel Rapid Storage Technology.
Open the RST control panel, disable linked power management in the performance options, and then restart the computer. This method is suitable for the newer version of RST driver, but not for the old version of RST driver or the pure driver version without control panel.
2. Uninstall Intel Rapid Storage Technology (RST driver)
The method of uninstalling RST driver is very simple, which can be directly uninstalled in the control panel programs and functions. After uninstalling, you need to restart your computer.
After reboot, use as SSD benchmark to check the driver, which should be displayed as msahci or storahci(Win 10), which indicates that the Intel RST driver has been uninstalled and restored to the system default driver. The compatibility of the system default driver is better than that of Intel RST driver, and it is generally not easy to get stuck due to power management reasons.
3. The method of saving energy by retaining the RST driver and disabling the link.
If you use an older motherboard (before Z77), you can't find the option to turn off the link power management in the RST driver control panel, and you don't want to switch back to the default msahci or storahci driver, you can consider this scheme. The support degree of this scheme depends on the motherboard manufacturer, and not all motherboards can find the same switch option in the BIOS.
Take the BIOS setting of Gigabyte motherboard as an example, directly set the active LPM support as disabled in the peripheral menu, or set the lower heat release of serial ATA port as enabled to disable the linkage power management of the corresponding SATA port, so as to reduce the probability of SSD card death.
If you still can't solve the problem after trying the above three schemes, it's time to check some unusual possibilities, such as 4K dislocation, loose SATA interface and data transmission error.

Troubleshooting of common faults of solid state hard disk;
Symptoms: The SSD is not recognized.
1, I can't see the new hard disk in the BIOS boot menu:
This problem is generally a common problem of brand-name computers. Press F 12 or F8 (ASUS) key to bring up the quick start menu when booting, but there is no SSD installed.
In fact, this is the phenomenon after UEFI started to disable CSM compatible support module. Because there is no operating system on the new hard disk, it will be ignored directly. As long as the SSD is installed correctly, it will appear in the menu. If you don't adapt to this phenomenon, you can turn on the startup CSM in the BIOS settings (set to enable).
2. My Computer can't see the new hard disk:
I can't see the new drive letter in my computer, which mostly happens when installing SSD. You can't see the new drive letter in the old system because the new hard disk has not been initialized and the natural computer can't recognize SSD. Only fake or second-hand disks returned by others will have partition letters in their hands.
Conventional solid-state disks are not initialized after leaving the factory. You need to initialize them manually (determine the partition table format, MBR/GPT) in disk management, and then format them in your home partition to see the corresponding drive letter in My Computer. Before initialization, the existence of the hard disk can be detected by the solid-state hard disk toolbox software.
