Looking for new hard drives...

[Natsu]

So, I am planning on getting some new HD for my desktop.

Problably a Caviar black WD 1TB for data but that's not the issue.
I am looking for something for my Os (Xp, 7 and 2008).

I know about SSD but they are way to expensive for me. I am debating between getting a 10000K raptor with 16 Mb of cache or 2 regular drive configured in raid 0...

Anyone has tried those setups? has any suggestion or can suggest anything better?

I'd go for the 2 RAID drives. If your hard drives don't crash ever, it won't really matter - but if by some chance one does, the RAID is definitely the better option.
