Hard Drive RAID0

[x2 3600 rules sazakky]

I currently have a "Samsung HD501LJ 500gb SATA2 16mb cache" hardrive in my system and thinking about RAID0 setup with another 500gb.

But the problem is, do u need to have another identical drive for RAID0 or not?

ALso, what kind of performance boosts can i expect

 

[Emulex]

with intel matrix raid = no.

the raid size will the lessor of the two drives in size

 

[lambchops511]

no need for identical drive

you would only be getting a perf boost on reads, writes would be just as slow...
