I want to buy a Sonnet Tempo ATA 133 PCI card and setup a RAID for performance sake. Here are my questions: 1. Which form of RAID is faster? Mirrored or Striped? 2. Will 2 identical drives give better performance? ie. same model, size etc. 3. Will I be able to boot from this RAID? 4. Is it good enough to setup this RAID from Apples disk utility? Please feel free to add any important info I may have forgotten to ask about.
