I'm looking at getting one of the new Mac Mini servers to play with at home and would like to set it up to use RAID 0 to try and get better performance out of the 5400 disks. I have a couple of questions. Can anyone give me an estimate of percentage speed up for reads and writes over a RAID 1 and/or using the two disks without RAID? How are the disks configured when the unit is shipped? To use RAID 0 will I have to reformat and reinstall, presumably using media mounted on another Mac with an optical drive? Thanks for any help with this.
