RAID0 doesn't require any calculations other than which block to read from (nor does RAID1), so software and hardware should be the same speed really. Booting from raid0 would probably be tricky. If you make /boot be a plain simple partition on the first disk, and install the boot loader to the MBR of the first disk, then you can use raid0 for the rest of your stuff across the remaining space without any boot problems. RAID3/4/5/6 is where XOR calculations come in, and hardware raid might be worth while. Hardware raid is also nice for making booting simple since the whole raid appears as one disk to the OS. Fake raid does that too of course. Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
