Hi,
My laptop came with two 128GB Lite-On SSDs in Raid 0 configuration. I'd like to break the array and use the SSDs as two separate drives. Can someone please tell me how do I go about it? There's no option in the BIOS to disable it, tried both UEFI and Legacy mode. The option to change Sata mode to AHCI from RAID is always greyed out. I think there's no point in keeping the Raid 0 configuration. I do not notice any performance gain
Symptoms
User can't delete RAID array, RAID option greyed on BIOS.
Diagnosis
User can create the RAID array via "Intel Rapid Storage Technology UI" (iRST) on Windows but can't delete RAID by "iRST" and RAID is the only option on BIOS (AHCI option is missing).
Before deleting the RAID array
Always remember to do the windows recovery media before running the RAID tool to delete the array.
With the help of the Acer Care Center (pre-installed on your system), you can create the windows recovery media on an USB stick, so you can reinstall it later.
In the AcerCare Center, click Recovery Management -> Getting Started, and then follow the instructions.

You can also perform a backup of your actual windows installation, so using the windows recovery media, you can reload your OS at the time of the backup.
Press Windows logo key and type "backup"
click on "Backup and restore" and then follow on screen instructions.

Solution
First of all, check the Volume name of your array on "iRST".
Press windows logo key and type "intel"
click on "Intel Rapid Storage Technology"
click on "Yes" if prompted
check on the right side, under "Storage System View", that "Volume_0000" or "OEMRAID0" is the name of the array.
if Type description is:
RAID 1 or Recovery - no data will be lost
RAID 0 - all your data will be lost - you will need to re-install Windows

Thanks! Worked flawlessly. I now have two seperate SSDs, and they perform as fast as they did while in RAID 0.
Thanks for this, let me install my 512 intel 600 drive and then unbind the two 128s it came with. Nice explanation!
Hello,
I own a Predator G9-593 and when trying to follow the steps I got a message on the Command Prompt that said "Intel (R) RST CLI version 14.8 cannot be used with version 15.2 of the driver"
What should I do?
Thank you in advance.
For anyone having the "Intel (R) RST CLI version **.* cannot be used with version **.* of the driver" issue you need to download the RST CLI version to match the driver version.
If the driver version is 15.2 then you need to download RST CLI v15.2.
Google it to find the version you need.
Once downloaded replace the old rstcli64.exe with the one you downloaded.
I have a predator g9-793 (ssd 250 gb et 1to HDD).
(Intel rapid cli 15.2 cannot work with version 16.0 of the driver.)

or you can try this (i don't have a RAID system to test it):
1) press Alt+F10 at boot to enter Windows recovery then choose troubleshoot - Advanced options - Command Prompt
if this worked jump to point 8)
It will take some hours to completly wipe the HDD and probably you will need to re-install windows 10 from scratch, so backup all the data you need!
