Then do another quick install to make a RAID0, and run the same benchmark for the same number of iterations. You can tell for yourself by doing a quick install on a single disk, and then running an IO-intensive benchmark like bonnie++ for a few hours. I didn't find the increased speed to be that dramatic, and I didn't need the array to look like a big disk. For some people, that's a risk they're willing to take for the increased speed. The downside to RAID0 is that if one drive fails you lose everything. It's sometimes called striping and does make it appear as though you have - in your case - 1 500 GB drive in the place of 2 250's. The RAID0 isn't really RAID in the sense that it is not the "Redundant" in RAID. However, that has been with RedHat Enterprise Linux. I have set up RAID0 and RAID1 on a few servers. ![]()
