SSD RAID Compatibility

I currently own a single 64gb Samsung 830. I'm looking to buy another SSD soon and I wanted to RAID it with the 830. The SSD I want to buy is the 120gb SanDisk Extreme. I've never done a RAID before and don't know much about it so I wanted to know if I can even do it with these two devices. Would I run into issues since they are different sizes and have different Controllers? I head that RAID 0 will only use as much space as the smalles drive, forcing the 120GB down to 64. Is this true? Also if you think there is a cheaper and better option for me please let me know.

Thank you

    Correct. If you create a RAID-0 array with a 64GB drive and a 120GB drive your array's total capacity (before formatting) will be 128GB (64 x 2).

    Just use the 120GB drive as your O/S drive and the 64GB as a backup/storage drive.

    Yeah that's probably my best option. Thank you!
