Hi. I am running the latest version of Mac OS 10.4 and have a 250GB HDD installed. I want to get another 250GB HDD and setup a RAID 0 striping configuration. I had a look at apple site and it has instuctions how to do this in disk utility. My questions are 1) I have alot of data on my primary HDD... to setup the RAID 0 configuration, is it just as simple as selecting RAID 0 in disk utility.. or will I lose data on the orignal drive? 2) Will I get the combined capacity of both HDD in RAID 0 eg 500GB ?
