Thinking about Raid 0 for two drives

I have a 1TB WDC Black and a 640GB WDC Blue, their both 7200RPM drives, I just want to know if there'll be any significant read/write speed improvement or overall performance increase.

Normally you want to use the same 2 drive sizes of the same type purchased at about the same time to do a raid 0. Raid 0 also means if either drive fails they both fail so you better have a backup. The speeds of the read/write usually about double (minus some overhead).

RAID 0 with 2 drives - 2x the size of the smallest, and the speed of the slowest.

So you're throwing away 360GB of the Black, and dragging it down to the speed of the Blue.
Ideally, you want two similar or identical drives. It will probably 'work', but results will be non-optimal.

And if this is for your boot drives, I wouldn't. Far too much hassle.
An SSD for the OS and applications will be much faster.
