    OK Folks,

    Here is the deal. I have an HP Envy 17, running Intel RAID 0 over 2-500GB Hard Drives. For some strange reason, unfortunately one I did not catch until last night, is that the RAID 0 is currently setup with a 32KB Data Strip, even though Intel's own guidance states it should be a 128KB Data Strip. So it is what it is. The problem, in order to change it, I will need to delete the current RAID and create a new RAID with the new 128KB Data Strip. I have been running the Envy for about 2 weeks, so although it will be a pain in the butt to make the change, at least it is early in the game. My main question at this point, although somewhat mute (Since I have confirmed on the web that my performance will increase with the larger Data Strip), is to whether or not I will in fact realize the performance gains.

    So can anyone out there tell be what there thoughts are on this unique situation and what they would likely do if in this situation? All thoughts and suggestions are very welcome, so please lend your advice.....

    Thanks!

    a bigger data stripe will give you better performance, but unless you run a server off your envy (lots of iops etc...), i don't think you will see a massive difference.

    I would stay as you are and change the stripe size when you decide to reinstall windows as opposed to reinstalling windows for the sake of increasing the stripe size.

    Thanks, but since I won't be upgrading windows anytime soon, I'm going to do it today, since I only have about a weeks worth of setup to my Envy and have backed up the stuff I needed. I figure the longer I wait, the less I will want to do it.. This way I get it done and get to receive the benefit of doing so...

    Are you running Windows 7 Professional or higher? If so, you could always to an image backup of the entire physical disk to an external drive. Then once you're done re-doing the RAID, you can just restore the image backup. Windows never has any idea what the RAID is doing, so this approach should work flawlessly, without requiring any massive amount of work on your part. Just make sure you create a "System Repair Disc" beforehand that you can boot from after re-doing the RAID. That will enable you to startup and "see" the external drive to restore from.

    Alternatively, you could use some other image/Ghosting software to create an image of the drive and restore it.
