    Ya I'm here, just been super busy lately, so I haven't had a chance to be in the forums as much as I'd like lately is all.

    I've never had a problem doing it. Ya recovery/repair will still happen on the RAID 1 if a failure or error happens.

    I've used RAID 0 for my OS, with a RAID 1 backup array, and anytime there is errors on the RAID 1 it would rebuild itself and not affect the OS/RAID 0 array while it was working.

    My only concern would be performance why the rebuild was taking place.

    Say for example thew RAID1 was two 750GB sections od the disk and that one drive required a full rebuild to sync with the other mirror. Surely performance of the system as a whole would be aweful until the rebuild was finished. If Normal OS function was prioritized over the rebuild by the software in some way then the rebuild would be slow. It's a worst case scenario, but 700GB of data takes an age to rebuild on seperate drives, let alone a single pair woth both RAID0 and RAID1 being asked to function at the same time and serve an OS.

    I can't think of this forum without u guys ;) But if everything goes ok I'll get some performance improvement right? I'm still stuck at that "zero performance" thing Psycho101 :)

    Yes mate, you will definitely get a performance boost.

    The no performance increase until 4 drives only applies to RAID10 which is a nested RAID level and not what you'll be setting up. Your arrays will be classed as seperate RAID 0 and seperate RAID 1 and should function normally within the requirements of those RAID levels, ie two disks needed, RAID0 section will be divided into chunks and files split into those chunks then written/read simultaniously. RAID1 will be mirrored so two identical copies of a whole file are written, one to each disk.

    For the most part it should work quite well otherwise I guess Intel wouldn't offer it. LSD also said he had decent results.

    Don't let my concern about performance while the RAID1 is being rebuilt as a rebuild should be a rare occurance anyway. I was just curious as we all know what mechanical HDD performance is like when they're asked to do two or more things simultaniously, each involving a lot of small transfers.

    When you complete instalation of everything on your RAID0 array, as long as you do an image with Acronis, you should never ever have to worry about that section of the drives. I recommend that if you have Steam for playing some of your games, you backup all your installed ones onto the single backup drive now using steam's built in function, then just install Steam on the RAID0 and no games before taking the image. I say this because my steam games take a about 120GB, and that can be a lot to have to re-image if the priority is accessing data on the RAID1. This way the RAID0 OS is up again super quick and you can access the critical stuff sooner, then use steam's built in program again to restore your game files etc.

    Rebuilds never had any effect on my systems, of course when they happened all I would be doing was browsing so I'm sure they didn't take much of the disk or other resources.

    It probably would slow things down a little bit if you were trying to heavily use the system, but if just browsing or reading email, ect you will be fine.

    That's good to know.

    I'd just heard of epic rebuild sessions for some people , probably on parity RAID though. From experience with a couple of company RAID systems, rebuilds lasted over 24 hours, probably due to huge amounts of data though and likely many many connected disks.

    So I'm gonna go for it :) Hope not much system lockups occur; especially games. I fear that the first lockup will break my raid0 :) Now I have some decent info thanks to you, I can go for it. Thank you both.

    Let us know how it works out for you.

    The only real time you should have rebuild issues is when you try pushing overclocks, or have instability, or of course if one of the disks starts dying or something.

    I only ever had them when trying to push overclocks, and then when it wanted to rebuild it generally would check for errors and find none or spend a while rebuilding and still say no problems found.

    I don't plan to oc in the near future. My q6600 at stock still handles all of the games and apps I'm interested ;) I'll let u know how it'd go (maybe some future tense mistake here) :)

    Well if you do, just get it all stable before you start using the RAID 1.

    And when I mentioned overclocks, I meant I was pushing things very hard at random times without stability testing, so you will probably be fine anyway if you aren't trying crazy overclocks.
