Hi

I have a Gigabyte Gaming 3 Z170X Motherboard (UFEI, BIOS Version F6)

The motherboard currently has a DVD RW Optical Drive, a Samsung Evo 850 500GB SSD, and two Seagate 1.8TB HDDs attached. Running Windows 10 Pro x64.

I want to RAID the two HDDs in a RAID 1 config. I currently have the BIOS set to AHCI mode, and I can only RAID these drives if I change to RAID mode. However once initialised, I can change back to AHCI and the array stays working and I can use it.

...UNTIL I reinstall the OS. Then the array breaks into two separate drives.

In AHCI mode, there is no RAID option (Rapid Storage Technology menu), so I do not understand what is going on. I am using AHCI mode as I heard it was better for SSDs (something about TRIM..?) but I cant have the array randomly dismantling itself. I cant see why the BIOS should alter the RAID settings when I run the "Refresh my PC" option in Windows.

The question is, should I install using the RAID mode, as it obviously is meant to be used. I do not know much about hardware. I am a bit of a pleb. I just need to decide before installing Windows again as Windows throws a kernel panic when I try to boot into the opposite mode to what I installed in (obviously, as there is no installed driver).

Thanks :)

Do I then stay in RAID mode?

Will it slow the SSD down much?

I apologize, I misread your original post.. The RAID array should be in RAID mode, if it still works I imagine its cause you had RAID1 and its not actually acting as a mirror anymore - just 2 standard drives?. Does it show as 2 individual drives now?. If it were in RAID0 it would break the array and you'd most likely get a message like "Missing Operating System"

I would RAID1 the HDDs for storage and use the SSD for Windows! better yet buy a second SSD and RAID it for Windows, and have your HDD RAID for games, storage etc
 
Oh yeah, that is my plan. I just mean in the BIOS, I have the option of RAID or AHCI mode to use for the entire set of disks. I should use RAID mode then?

Please can an Admin move this to an appropriate location? Many thanks in advance.

Edit: thanks John or Chromewell or whoever moved this
 
You need to reinstall windows after you set up the raid array. Back up any data first, set up raid in the bios. Install windows and copy back your data.

Also moved this to motherboards.

Which SATA mode do I need to use? AHCI or RAID? (Probably really dumb question)
