Take a look at this guide:

http://www.howtogeek.com/howto/36504/how-to-create-a-software-raid-array-in-windows-7/

EDIT: To clarify: In this guide a spanned volume is made, which has no fault tolerance. That means that when 1 disk goes down it takes the whole setup with it.

You can go with something like mirrored volumes. This is a more secure option, but the drawback is that the storage space isn't as efficient as it could be with no fault tolerance, it is up to you to decide this.

Take a look at this document for more information.

If one of the disks goes, then can I simply see the files and folders in the other disk? Or do I lose the whole thing? –  user57813 Dec 20 '10 at 13:01
    
It is a spanned volume, so there is no fault tolerance. If one of the disks fails the whole setup fails. A solution is to go with mirrored volumes, a more secure option. The drawback is that storage space is halfed at least. Take a look at the table here: en.wikipedia.org/wiki/RAID#Standard_levels for more information. –  Duijf Dec 20 '10 at 13:07

Windows 7 include software RAID support, so you can turn two disks into one, but you will take a performance hit... Try a RAID level 0 solution for your needs
