Rapid Storage Technology (RST) driver question

[Burner27]

Let's say you installed 2 x 80GB SSDs in RAID 0 using the Intel RST 9.6 drivers. You used it like that for a while and now want to go back to using a single drive setup. Would this plan work (yeah i know I have to try it to actually verify, but I figure I'd bounce this idea in the forum first):

Make a backup image of current setup using Acronis TE 2011
Reboot
Go into Matrix utility, break RAID, reset drives to 'Non-Member disks"
Save
Using Acronis Boot Media to restore image to single 80GB SSD

What do you think?

I am figuring this should work because I have some "Non-Member disks' now along with my 2 x 80GB SSD array and when I benchmark using AS-SSD, the RAID array and single drives both are listed as using 'iaStor'.

Is there any downside to doing this versus using the AHCI driver?

Thoughts?

-"Is there any downside to doing this versus using the AHCI driver?"

-on a single drive it would use the AHCI driver of the iastor software .
-you would have do a secure erase to put the ssd back to flesh\new.
-intel has it's own cloning software[Acronis] try that.

NO good..... In Raid0 you lose it when you break the array. I built 7 arrays today in 0 and learned this quickly. In RAID0 half of the info is on one disk and half on the other. Imagine this, you have to carry 20 bags to a different spot. Now if there were 2 of you, you would each carry 10. Thats how it works with DAIS except half of the load goes to each array each time. That way you can read/write twice is fast.

I could see no prob with migration software however.

-That's what I figured.
-I don't want to 'flesh' my drive as that would be rather difficult (See Star Trek: First Contact to see computer parts merged with flesh--haha)
-I already own Acronis True Image 2011.

Thanks

I know that if you break the array you lose it. Hence, the reason my first step was to back up my current image using Acronis TE 2011. I am very familiar with how RAID works, so your explaination of how RAID operates is not unfamiliar to me.

My question was in regards to going back to a single drive FROM a RAID 0 array. You see, Windows doesn't really know (almost) what kind of drive you install it on. It just wants to know where it is going to install and run from. It would probably treat a single 120GB SSD the same way it would treat 2 x 60GB SSDs RAIDed. As long as it had the right drivers. Since RAID disks and 'non-member disks' in the ICH10R use the same driver, I don't really see the switch from RAID to non-RAID as being an issue.

pretty much want to clone that to a non-raid (ahci) single drive. most intel matrix raid will tread drives not part of a raid as AHCI and those part of the raid as RAID - obviously you want AHCI for trim/etc for extra performance.

also some old lame software like adobe will freak out when you muck around with the drives and make you re-activate which is a serious waste of time.

Ok what I tried worked!!!

Then I tried making the switch to AHCI mode via registry hack. That didn't--and I expected it not to.
