I'm not sure if I should post this here or over in the hard drives thread. So, I'll go here first ...

I would like to have RAID 0+1 on my system (system in sig - ie, IC7-G/875P chipset).

I have 2 120gb SATA Seagate drives running in RAID 0 off the SouthBridge and then I have 2 120gb PATA WD drives running in RAID 1 off of the SIL. Currently, I have my OS/C drive running on the RAID 0 drives. RAID 1 is on the SIL and has no data yet ... just formatted and ready to run. (the RAID1 drives are PATA drives running with the Seriell2 cables)

So, I *thought* I'd be able to do this but maybe I didn't understand correctly what RAID 0+1 is. I thought that I could make all my data copy over to the RAID 1 drives from the RAID 0 drives. But, in setting this up as I have it set up now, I don't see how to accomplish what I want.

So, I've posted over on the Abit forums and gotten one response (which basically said I couldn't do what I wanted) and thought I'd post here to see if I thought through this incorrectly and confirm that this isn't doable.

Let me know if you have any thoughts on this.
Thanks in advance!

The reason you're finding it un-doable is you've got 2 seperate RAID controllers. To have true 0+1 you need one controller for all 4 drives.

so, really, there's only one way to do this and that is to get a PCI based card and then hook all the drives in.

Shoot... I thought I had this figured out!!!! Learning learning learning.... ;) 

Thanks - appreciate it. -ot

yes, with that setup that is the way to do it. Probably not really necessary as long as you back up your important files regularly.
