A question on installing - FC5 32bit and M$Win2000

Hi Eugen,

Apart from using a software RAID card connected to HDs, I never use
Linux/FC/RH software RAID before.  I'm interested to have a test. 
Please help me to understand

1)
Do I need 2 HDs for RAID 0/1/2?

2)
If 1) above be "YES", whether both of them have to be connected as
master on primary IDE and Secondary IDE respectively.

3)
Is there a visible improvement on operation in running RAID 0/1/2


Please advise.  TIA
