Both AHCI and RAID

Hello,
I've got 1*60GB SSD and 2*1TB HDD, I would like to run windows on the SSD and set a RAID 1 with the two HDD, but...
First, I only connected the SSD to instal windows, with the AHCI activated in the BIOS.
When done, I changed BIOS to RAID, and setted up my RAID... and windows 7 no longer boots up. If I turn my BIOS back to AHCI, it works, but I haven't got my RAID...

So I can't get both AHCI AND RAID ?!

  1. It should work. You just need the right boot order setup.
  2. But if I choose RAID instead of AHCI in the BIOS... it will not able garbage collection, TRIM, etc...? So it will deteriorate my SDD, isn't it ?

    AHCI is a subset of raid.
    You need to set up specifying sata as raid. use your two drives in a raid-1 array, but do not include the ssd. The latest Intel drivers will pass the trim command to the ssd if it is not part of the raid array.

    I dont think so. Unless you have TWO SATA controllers in your mobo.

    How about this...

    Set AHCI on. Once in Windows
    Go to Disk Manager
    Change the both of 1TB hdd disk type to Dynamic
    Create a Mirror volume out of these TWO drive.

    This is pretty much the same thing that you're trying todo
    software raid mirror, instead use intel raid drivers now you use OS raid
  5. To do what you're describing you have to set the controller to RAID mode. As long as you're running the SSD itself as a single drive, and as long as you have the latest Intel chipset drivers, TRIM commands will be passed to the drive even though the controller is not running in AHCI mode.
