I currently have 2 hard drives in Raid 0 config using onboard Nvidia Raid controller. If I was to purchase a decent Raid card, could I move those drives over to the Raid card without blowing away my OS???
 
no, you can not. You could, however, setup a new RAID on the secondary controller and move your data. Once your data's off to the new drives on the new controller (if it's a decent RAID card) you can migrate the RAID level to 5 or 10, or something else via the RAID level migration tool, and then use on demand RAID level expansion to expand the array's usable space. This assumes that all the drives are the same size. Otherwise, you'll be stuck creating two separate arrays on the new controller.
 
No, because when you boot to the new raid card you'll have to reinitialize the logical drive within the new card. Some high end raid cards have the ability to inherit a new drive I believe, and expand the span.

Anyways, why would you want to buy a raid card? You're not gaining anything.
 
New hardware deserves a new install thats my motto.... I backup all my data nightly so I can just reinstall the OS if I have to and some programs restore the data over the network from my WHS and im up and rolling.

Becasue NVRaid blows

Because I've never had a raid card and I've heard they are way better than onboard raid!

For any RAID setup other than RAID0 or RAID1, yes hardware RAID cards are better than onboard RAID. However, if you're just going to use RAID 0 or 1, no point in buying a RAID card.

Then again NVRAID does suck when compared to Intel onboard RAID. Though for the cost of a decent fakeRAID card (roughly $120) you could just buy newer and faster drives like the WD6400AAKS that would perform on par with most RAID setups.

And no, you cannot move your NVRAID setup over to a RAID car with the OS intact.

I doubt that hard drive is as fast as a Raid setup. Here is what I get now with my Raid:

min: 119.0
max: 224.0
avg: 177.9
access time: 19.7
burst rate: 339.7
cpu usage: 8.0%
 
Having a RAID card also gives you the option of not having your array be dependent on the mobo. I wonder if maybe you can make an image of your current setup, copy that to an external drive, and then reimage it onto your new RAID array? I've never worked with RAID+images so I'm not 100% if that's possible.

I wouldn't doubt it, you might have some increased performance with benchmarks, but keep in mind, a raid 0 array can actually decrease your performance. And while you enjoy your synthetic numbers, keep in mind, your performance comes at a great tax to your system resources (hence your cpu usage right there).
