Motherboard RAID0 OS reset

Hi all,

I have recently purchased an ASRock Z68 Extreme3 Gen3 and am planning to have my OS on a RAID0 array, controlled by this motherboard.
My question is: Will clearing the CMOS make me unable to read my OS on the RAID0 array?

I have asked that to the ASRock tech support but the answer I got was that clearing the CMOS will reset the BIOS configuration to factory defaults, including the hdd configuration. But I already knew that.

What I really want to know is whether after having reset the BIOS, can I set the hdd config back to RAID0 and boot on my OS again fine? I was thinking that maybe when I would set the hdd config back to RAID0, it would clear the hard drives and create a new RAID0 array.

Thank you for your help!

    Yes, but may I suggest that you try it right after the initial OS install?
  2. So it should work. Ok thanks.

    Yes, but may I suggest that you try it right after the initial OS install?

    Yes I also thought to do so (: I just wanted to make sure in advance...

  3. Clearing the CMOS will destroy the array, because the default settings in the BIOS are not set for RAID 0. But, all you have to do is go back and set everything back to the way it was, before you mess with anything else, including the RAID BIOS as well, and it should re-establish the array.
    I am not going to go into detail and tell how bad an idea this is your are thinking about doing, there are many, many, many threads already on this subject.
  4. Right, yea I've seen alot of stuff on this, but how to resist an SSD RAID0 array for the system, the ultimate speed! (I have 2 Agility 3 60GB)...
    I'l just back it up on another drive and restore the backup when I do that then if it doesn't work...
    I'l try it first, but I'l also do a backup anyways...

  5. What could you possibly being doing with an OS drive that would use the bandwidth of a single SSD, let alone 2 in RAID, and you realize that running a pair of SSD's in RAID means Trim is disabled?
    But to each his own, good luck and happy what ever it is you do with your setup!
  6. Yes I did look at the drawbacks of not having TRIM, but its probably just going to decrease the lifespan of my SSD's to about a year and a half right? (They had about 8 years lifespan accoding to Tom's).. I mean, by that time I'l get new ones because they'l be better and cheaper...
    Do you really think it is not worth it to to do this, even if I get 1GB/s average read speed (they're both 540MB/s average on Tom's)? I mean everything would open up faster, workflow would be so much better, everything so much more speedy!?


    PS: I got the 2 agility 3s 60% off at newegg so I'm not concerned about the price of those SSDs
  7. 1 SSD is so fast, its nearly "instant" already. I don't see how putting another one in RAID is going to make a noticeable difference.
  8. If you clear the motherboard CMOS, it only clear up BIOS setting.
    1. If your computer is continue supply power to the SSD / harddisks. The array setting will not missing
    *You must restore the RAID setting in BIOS*.
    2. The SSD and tranditional harddisks are same. Keep the power supply to SSD or harddisks.
    3. Don't not change SATA, SAS, 1394 ports or NAS * take out one of internal harddisks.

    4. If you using highend RAID card with batteries (backup). If you cut off the power, the batteries will be keep RAID setting unchange.

    I did trade and using RAID around 11 years.
  9. Additional for
    4. Motherboard running array is under software and don't provide hardware RAID functions*Single processor + RAID chipset + Battery.

    Software RAID need to keep power supply & connection ports unchange.
    Hardware RAID allow
    1. hotswap
    2. Replace harddisk under RAID 5,6,1 & 1E.
    3. Dis-continue power supply*It must need a battery on card.

    Now, the CPU speed is enough to process software RAID and working very well. Therefore, purchase hardware RAID is not neccessary.
  10. SSD could be provide bandwidth live memory, but my point of view is: You computer could be provide same bandwidth to you. It is not. Because PCI-E, PCI, Many PORT and sharing one bandwidth. How many bandwidth you could got by SSD?.

    To get the max benifit about SSD: In the BIOS setting: Disable all COM 1, 2, traditional printer, PS2 & ATA33,66,100 Ports. Buildin sound chipset & LAN. Disconnect all PCI linking ports.
  11. Actually, I think I will take everybody's advice and stop being stubborn (:,2800-8.html definitely showed me I need TRIM (:
    I'll just put my OS on one and my programs and games on the other.

    Thank you all
