Hi I bought a Western Digital Caviar Special Edition 250GB 2500KS SATA-II 16MB Cache - OEM - filled up a lot quicker than I anticipated, do I need the exact same drive to do raid 0?
 
Nope, you can raid 0, with different spec/size 2 or more drives. Although the stripe set can only have a maximum size of the smallest harddrive.

Although hardware manufactures will always recommend that you use 2 of the same identical drives to get the very best performance.

From your post though, it just looks like your needing more space, and not really a raid0, which would offer no redundancy, so if 1 drive fails you loose everything.
 
Toytown is correct, you don't need to buy exactly the same hard drive but it is certainly better to do so.

You should also remember that to use Raid0 you will have to build the array which means wiping whatever is on your current drive so you will have your new hard drive + 250gb free space = loads of space ;)

I'd again agree with Toytown though that you would be better getting another hard drive and not raiding them partly to avoid the hassle and partly for the lack of redundancy they mention.
