Windows 7: Raid vs AHCI

Raid vs AHCI

While experimenting with a USB bootable Macrium Restore thumb drive I created, I was looking in my Bios and noticed the SATA controller was set to Raid. I have only one internal HD.

I changed it to AHCI and booted up, got a notice that new drivers were being installed and rebooted.

The computer seems to be running the same. Wondering why HP had it set to Raid.

So what is the difference between the two settings?

I'd let AHCI if you just have 1 HD

With only one drive AHCI and RAID perform the same, at least for Intel controllers.

Thanks for the replies...

I'll just leave the AHCI setting for the controller.

So I picked up a pair of Corsair Force 120Gb SSD drives and set them up in RAID 0. Figured I could just slap them in, load the AMD RAID drivers then do a clean install of Win 7. Which Iíve done and everything seems to be working fine. Now reading about the performance benefits when setting your...

I have a friends HP system I'm fixing for him. His hard drive died, totally inaccessible (750GB SATA 3 Seagate). I ordered the recovery DVD and a new hard drive. In BIOS, the SATA controller can be set to Raid, AHCI or IDE. My question is, which is the right one to use. It was set to Raid but...

Hi all, My current 7100 RC installation sits on two hdd's in RAID 0, provided by the onboard controller; in this case an Intel IHC10R. I switched the disc mode in BIOS to AHCI; the intent was to reformat and re-install a BSD based system on the second drive, 7 back on the first, and dual...
