I have a 320gb HDD with my OS on it and I had just installed a second drive that is 1TB. Can I setup RAID 0 with just the OS drive and the 1TB drive?

say that right in that winki link I gave above - not hard to read and understand to me

''RAID 0 setup can be created with disks of differing sizes, but the storage space added to the array by each disk is limited to the size of the smallest disk. For example, if a 120 GB disk is striped together with a 320 GB disk, the size of the array will be 120 GB × 2 = 240 GB.
raid 0 don't mirror you would need to set up the array and reinstall from scratch

and I assume you know all the risks tht come with raid 0 as well ?? I would not stor anything on it you may want to keep that maybe hard or not able to replace [family photos and stuff like that ] it just performance only ..

RAID 0 (also known as a stripe set or striped volume) splits ("stripes") data evenly across two or more disks, without parity information, redundancy, or fault tolerance. Since RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail; as a result of having data striped across all disks, the failure will result in total data loss.

When you do ANY kind of RAID besides what everyone else has said they drives MUST be the same size! If they are not then they all become the same size as the smallest drive. If you did a RAID 0 of your 320 and your 1TB it would only use 320GB of your 1 TB giving you a 640GB hard drive. The rest of the space on the 1TB is gone for ever unless you break the RAID. RAID 0 should NEVER be used unless there is nothing on the drive or you have regular backups of everything.
