Hi guys.

I have a 120GB SSD and a 500GB HDD. I installed both devices on the SATA3 ports on my motherboard. The SATA3 was set by default on operation mode IDE.
I installed windows and everything is working fine. I installed the programs that would benefit from SSD on the SSD and the other usual programs on the HDD.

I read around and it seems that SSD is faster if it's set to AHCI instead of IDE? Is this correct?
I tried setting SATA3 to AHCI but it gives me a bluescreen. Maybe because HDD is also on AHCI?

What do you guys recommend me in this situation? Leave on IDE, or put only SSD on SATA3 and AHCI? Because AHCI is faster?

Thank you.

You got the blue screen because your windows install used ide drivers, not ahci.
There are methods you can try via registry hacks to fix that, but the simplest is to set the sata mode to AHCI and reinstall windows.

Why AHCI?
AHCI enables trim. That is the sata instruction that lets the ssd reuse a free block without reading and rewriting it as empty.
That improves the speed of deletions and also preserves endurance. A ssd block has a limit on lifetime writes.

you would of had to set it to ACHI before you installed the OS. if you find your not getting the performance you want out of the SSD you could always try doing another clean install. i don't think cloning would work in this case because the image was installed with the IDE option

Yes AHCI is faster for both hard drives and SSDs than IDE mode. You could just have the SSD on AHCI mode if that is an option or you could try thishttp://www.overclock.net/t/1227636/how-to-change-sata-modes-after-windows-installation and it will allow you to swap your hard drive to AHCI mode as well.

Here's an article that explains the registry edit you need to make before you can make the BIOS/UEFI switch to AHCI: https://www.data-medics.com/data-recovery-blog/how-to-enable-ahci-after-installing-windows/

I run that command and cmd is telling me trim is enabled. Do you guys think I am good or I should still try an OS reinstall with AHCI enabled?
