Raid 0+1/10

  1. 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?

    Yes, you must have 4 drives. Two drives in the stripe & two drives to mirror the first two. If you want speed & reliability with 3 drives, setup a RAID-5 system.

    Which would be better in your opinion-a Raid 0+1, or a Raid 5?

    RAID-5 but it's not widely available. Asus has started to offer RAID-5 capable SATA controllers on its motherboards otherwise you wold have to purchase a PCI SATA (or IDE) controller which does support RAID-5.
