I bought a Mac Pro Quad 2,66. It came with a 640 GB Western Digital Caviar Blue Disk. I consider to buy another 640 GB WD Caviar Blue and put both in a RAID0. Is it best to install the system on this RAID for maximum speed or is it better to install macosX on a 3rd disk that isn't part of the raid, e.g. a Samsung Spinpoint 1 TB

    OS X will boot from and run on a RAID 0 stripe, and it does improve the speed noticeably. The only down side is that I had trouble installing firmware updates, I had to update from a single drive OS install.



    I would make doubly sure that you have an automated backup system going. I'm not running a RAID 0, but even then, I have SuperDuper updating a second bootable drive daily.

    Thanks!

    I have a 3rd drive not in the RAID, therefore backup or firmware updates shouldn't be a problem.
