Yes, I can confirm that version 220.127.116.112 is very old, it does not yet support TRIM.
So even if TRIM is supported by the SSD and Windows uses that command (which may be confirmed by fsutil), the TRIM command actually does not "arrive" to the SSD.
Generally the Support -> Driver Zone ( https://www.hdsentinel.com/driverzone.php ) page shows recommended drivers for different controllers.
For this controller, personally I recommend using version 10.5
There are older / newer versions, but generally this version was one of the bests for such chipset and controller, which can be downloaded directly from https://www.hdsentinel.com/driver/stor_allos_10.5.0.1026_pc.zip
The "RAID mode" just suggests that by using such drivers, disk status monitoring is possible even when RAID mode is used/configured.
Installing that driver does not cause change in the disk drive configuration (does not "need" to have RAID configuration) and is safe for stored data.
Alternatively, you may attempt to get the latest driver from Intel (or the manufacturer of the laptop).
Or, you can try to change the current driver to Windows "Standard AHCI Compatible Controller" driver (or similar) as then TRIM will likely work. Then there is no need to download/install any other driver, this is included in Windows.
For this, please try:
1) right click on Computer, select Properties -> Device Manager
2) locate "Intel(R) ICH9M-E/M SATA AHCI Controller" device.
It is located in the IDE/ATA controllers or Storage controllers section.
3) Right click on this device, select Update driver software and
select "Browse my computer for driver software"
4) Select the "Standard AHCI Compatible controller"
Do not attempt to "search for updated drivers online" as this function usually never works.
Hopefully after changing to the Standard AHCI Compatible controller driver (and restart) TRIM function will work.
This procedure (just for a different controller) described at: www.hdsentinel.com/faq.php#trim
