OK, to start with, I have read anything I can find on Raid and I understand it. My questions come from the technical aspects. I want to use Raid to get the performance of striping 2 drives, but rather than have the security problems with errors, I also want the advantage of mirroring those 2 stripes. My understanding is that is what a Raid 0+1/10 configuration gives. What my technical question is, I am wondering if I can get away with this configuration with only 3 drives? How I would set up something like this is to set 2 Maxtor 200 GB HD's in the striped mode, and mirror those with a single 400 GB Seagate Barracuda. Is that possible? Or must I have 4 total drives of equal size?
