IHCR9 raid worth it.

I'm setting up a new system on an Asus Rampage. One of my uses will be video editing. Is it worth it to set up a RAID-0 array using the on-board IHC9R? I've heard this isn't the same as the true hardware raid you get with a controller card. I don't need redundancy, and these would be separate disk drives than the boot/os disk.

RAID-0 is great to improve sequential read/writes (your video editing) as long as you have little concern for the contents of the disk (or backup regularily). On-board RAID will fork all XOR (RAID processing tasks) off to the CPU rather than on a dedicated RAID controller. Generally the features of onboard are nowhere near that of a dedicated one (as well as speed with increasing amount of disks), however, with a 2-disk RAID-0 onboard you will get a good performance increase at no extra cost.

I agree. I use about 5% or less CPU when my RAID-0 on IHC9R is at 100%.
