BEST ADVICE.
===========

Do NOT use a RAID 0 array.

You have zero redundancy. If you lose one drive, you lose the lot!!
You can not recover from a single drive failure in a raid zero array, there is absolutely NO point to having one. Just have 2 1TB disks.

Your Gigabyte GA EX58-UD5 offers a hardware RAID option, via the second bank of SATA2 ports. That's assuming you have enabled the ports, plus RAID support, in the bios.

If the bank is active you should see a post bios <CTRL>+<I> RAID configuration option, which if entered will present a menu of options, that include creating a RAID volume, using 2 or more attached drives.

Once a volume has been defined, and you have booted into your existing Windows 7 install, you should be able to view the empty volume, in the Disk management option, of the Computer Management panel, accessed from the Control panel. Once formated, simply mount the RAID volume as a separate drive or under a folder, on your existing drive.

There are several Youtube videos that take you through the process e.g. http://www.youtube.com/watch?v=5L--ByVvXqw

Note: Hardware RAID 0 solutions have  historically offered a slight performance boost (for reading/writing multiple files simultaneously) over individually mounted drives, as well as offering a big bucket, single volume, to minimise the need to shuffle files over both drives, as they fill up. But as there's no redundancy with RAID 0 I'd recommend you look at backup solution, or a higher RAID number, as statistically a RAID 0 array will fail more often than a single drive.

Ok, let me try these suggestions and re post. The RAID 0 would be for a fast solution to store large HD video files quickly, using one of the other drives as a back up solution.  This velociraptors already spin fast so I'm not sure if I need the RAID 0 or not. Thanks for the info. I'll re post later.

RAID 0 gives you NO ADVANTAGE AT ALL except it can risk lose ALL your data if EITHER disk fails. NOBODY as an expert should advise you on configuring a RAID 0 array for storing ANYTHING you want to keep.

As you already note yourself, the velociraptors are FAST drives. Dont spoil the fact by putting them in a RAID0 array and risking your data.

That makes sense too considering they are faster than any other drive I have. Thank you, I will accept this as advice and re post for instructions on how to simply add hard drives to an existing system.  Thanks for the advice.

Neilsr: Per my post above RAID 0 can be useful tool for creating relatively cheap, fast and large volumes for parking transitory / temporary files on, e.g. raw AVCHD VIDEO, database dumps, system images..... Wouldn't want to use if for anything critical, but it is a useful toy.
