I wouldn't recommend doing RAID 0 with IDE drives. Let me give you my experience with RAID 0 and my Promise FastTrak66 (no hack). I bought two BAND NEW 10GB Segate 7200RPM Barracudas and set them up as RAID 0, and after about a week or two one drive failed (all the data was lost but luckily I make buckups). Well I thought, it is probably just a bad drive. So then I oredered two identical BAND NEW 20GB 7200RPM IBM drives with 2MB cache (4MB in total after set up as RAID 0). Guess what, after about one or two weeks one drive failed (lost the data on them AGAIN)! Both time I had to return the drives because it wouldn't FDISK! And this was on a system that the PCI was running at its standard speed of 33MHz, so overclocking didn't kill the drives. All I can tell you is, the reason I went with RAID 0 is because I wanted the HD performance without the SCSI price. Well looking back, I should have gone the SCSI route, it would have cost me about the same! I would ONLY recommend doing RAID 0 or 5 on SCSI drives because I just don't think the IDE drives can hack it.
As for doing RAID 0 on NT/2000, you can't do RAID 0 on your boot partition. Also, hardware is ALWAYS the best way to do RAID. Doing RAID 0 on 2000 is going to eat up much needed resources. Damn, I have 2000 Server at home just running Active Directory, Proxy 2.0 and with 128MB of ram it did a memory dump TWICE and KILLED Active Directory both time, and I had to reinstall! now I have 384MB and everything is fine.
