Question about a RAID setup

If I run two 500GB hard drives in RAID 0, can I use a 1TB single hard drive as a mirror? As in RAID 0+1 with three drives? Or do I have to use a second pair of 500GB drives?

  1. 0+1 will work with three drives... but it is not recommended... you would probably want a hardware raid of the stripe and software raid the stripe with the single disk...

    so what youre saying is, this setup will work, but it might have problems, right?
    what exactly do you mean by hardware raid?
  3. Best answer
    raid with the drives plugged into a controller card where the RAID is defined by hardware... as opposed to software RAID where the OS creates the raid. (hardware RAIDs are more efficient and more reliable)

    thank you. so ill probably go with that option, lol
  5. so if i set up a raid 0 with two 500gb hard drives, can I later get a 1tb hdd and use it to mirror the "single" volume created through raid 0? more simply, would it be possible to have a 1tb volume from 2x500gb striping, and the second 1tb hdd for mirroring the first volume?
  6. you're really better off getting 3 hard drives and doing a raid 5 or 4 and doing a 1+0/0+1

    just because something is theoretically possible doesn't mean you should ever do it...
