AHCI vs IDE - Any Difference or Preference

I recently built a system using a Gigabyte GA-Z68XUD3-B3 motherboard and Crucial 64GB SSD (CT064M4SSD2).  I would swear I had the BIOS set to AHCI when I installed Windows 7, but after install, see that it is at IDE, and no amount of BIOS changes to AHCI or edits to the registry will permit SSD use in AHCI.  Looks like reinstall with AHCI enabled in the BIOS or live with IDE. 

 

Does AHCI or IDE make any difference with the Crucial 64GB drive?  I can find no good agreement on this, but maybe there is something more definitive with the Crucial drive.  The drive holds the OS, MS Office, and two other small applications, with less than half the capacity used.  It is connected to a SATA3 connector on the motherboard.

 

Thanks.

definately better in achi mode, you have no NCQ in IDE mode,  and you should be able to use a registry fix with a reboot to fix that, no need to reinstall

I wish the registry fix would allow selection of AHCI in the BIOS, but it won't.  That registry start value can be changed from the original "3" to "0" and the BIOS set to AHCI, and Windows will not start.  In short, AHCI prohibits Windows from loading no matter what the registry value is.

i would try a different bios then, I also am on a gigabyte mobo and it should most definately let you boot in achi mode, may have something to do with that ssd caching on the z68 mobo

I thought AHCI is better than IDE right?

Hi Phil,

 

We would always recommend running our drives in AHCI over IDE.  There will be a pretty big performance drop if you run the drive in IDE.

 

I would recommend contacting Gigabyte directly to see if they have a work around of BIOS update that allows your motherboard to run in AHCI.  You will certainly notice a difference in performance between the two of them.

 

If you do have any other questions at all, please don't hesitate to ask.
