AHCI vs regular Native IDE

ahci has ncq that makes it much faster even on mechanical drives

I don't have an AMD system so limited advice on my part. But it is likely a driver issue.

AHCI has nothing to do with the Drives (HDD or SSD) it has to do with the SATA controller and how it communicates with the host system. A SATA drive does not care how the system is setup (AHCI or Legacy IDE), the SATA controller simply translate the older Legacy IDE to the respective SATA commands for the drive. AHCI simply removes that need for translating as well as expand the feature set that SATA supports.

The purpose of the Legacy IDE mode is because older systems (Windows XP) don't have support for SATA or AHCI.

I don't know much but i think this gentlemen is dead on .

Well now let's see how it goes! :)

That did the trick for 10 but no go on 7 so far! Keep getting the "device inaccessible" error despite the reg values change followed by a few restarts while still in Native IDE and no driver search conducted by Windows there. Since I have a working dual boot on both machines I guess I am stuck with the original option.

Sorry, can't help you with Windows 7, haven't used it or tinkered with it since Windows 8 came out.

According to the article, it's mostly noticeable on SERVERS. Maybe for desktops it's not so big deal of a difference. YMMV I guess.

Well the need to reinstall 7 just because of the blue screen that flashes for a split second is pointless since once the Native IDE setting is back 7 boots right up normally again despite seeing the prompting for the Startup Repair tool option. When trying that all you will see is the "device is unaccessible" message and press enter=bootOS appear.

I'll have to see what the board manufacturer has for AHCI drivers before trying that again. Having things set for automatic updates by itself won't see the drivers downloaded and installed by Windows. You have to go for those manually.

I gave up on that , Asus makes my motherboard and they have had only one choice available for years , the ACHI driver is from around 2010 if i can recall .

Thats why i went to a specialty forum and asked for assistance with my ACHI driver , there was much more recent versions but surprisingly to me the newest ones made no difference in my systems performance .

Now i stick to the saying "if your PC is functioning well don't mess with the drivers" , only update if your having issues.
