Hello. I have 2 SSD drives in RAID 0 currently set for my primary boot drive and would like to undo this to make them 2 separate drives again. The SSD drive is currently being run by some software SSD controller and not a hard one.

I would like to make 1 full system image of the drives to use on a new one. If I have the system image, would I need to reinstall Windows first to the new drive or just use the image to install it all back again?

Let me know if you need to know anything else! Thank you for more information.

I also have a program called Acronis True Backup 2.0 I believe it is called if that is better than using Windows default backup features?

Simply copy your data off or make an image and disable RAID. When you boot you will have two (unusable) HDD's. Then simply partition and/or format.

Moving from RAID (which typically indicates spinning drives) to an SSD, you should perform a fresh installation of Windows (especially with Win7). There are several settings required for the SSD to perform properly that are set during installation.

It may or may not work. It has been a while since I used win7 however [I think] you will need to edit the registry prior to making the image and doing the restore. This does require a reasonable level of skill and a clean install might be a better way to go. Here are the instructions for editing the reg. Always be sure to have a current backup prior to doing anything
To resolve this issue, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:
  1. Exit all Windows-based programs.
  2. Click Start, type regedit in the Start Search box, and then press ENTER.
  3. If you receive the User Account Control dialog box, click Continue.
  4. Locate and then click one of the following registry subkeys:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
  5. In the pane on the right side, right-click Start in the Name column, and then click Modify.
  6. In the Value data box, type 0, and then click OK.
  7. On the File menu, click Exit to close Registry Editor.

Note after doing the above, you would need to boot with the acronis boot usb; make the image and store on a drive or whatever. Once done with the image, restart and enter the raid [not system] bios and delete the raid array. Again restart and enter the system bios; set to ahci mode. Save settings and boot the system with the acronis boot usb; restore the image and you should be done. Again I would clean install however up to you.

Thanks for the replies all! Yes. I may just go with a clean install, but I'll try a backup or a system image first to see if that may work on the new Boot drive. I'll have to get a bigger one since the amount of info on the RAID drive is about 60%, so it would be more than the 2 drives separated.
