How to make Raid0 on mac mini Server

[vslo]

Tomorrow I will be installing the normal snow leopard in my mac mini server 2010. I want to make raid0 with the 2 500GB hard drives. But I dont know how to do it. I have to make it through the installation, or after it ? And is a raid0 so unstable that I HAVE to buy a back up HD ?
Thank you.

From the initial install screen, look up at the menu bar...

Utilities -> Disk Utility

Look for the RAID tab

Only bother backing up if there might be anything important on your RAID

I dont know if this is right, but I think you can do a RAID setup from within disk utility inside os x. But I am sure you can do it from the disc onna fresh format too.

There is nothing unstable about RAID-0. Unfortunately, hard drives fail. If either one of your hard drives in a RAID-0 array fail, your array is gone.

You should be backing up your stuff regardless.

Ok just to make sure. If I am doing the RAID0 with my two 500gb HDS inside the mac mini, I MUST do it when I am installing the system, right ? Otherwise I will not be able to make it ?
And what block size would you recommend ? 64 or 128 ?
I am trying to make it now, before reinstalling the system, but I cant drop my main HD into the RAID stripe.
Thank you!
