Raid 0:
So I know that raid 0 is the "fastest" configuration for hard drives, but I’m wondering how exactly it works, I heard something about it sends the data to both hard drives simultaneously making it twice as quick, but don’t know exactly how it works. Also can you please give me an example of when I would notice two hard drives working in raid 0?

10,000RPM hard drives:
How much faster are these than the 7200? How fast are they against two 7200's in raid 0? Would I really notice a difference b/w one of these 10,000's vs. two of them (10,000) in raid 0.

General:
What other stats should I look for when purchasing a hard drive, and what does the stat mean?

Thanks a lot Guys!
 
RAID 0 will not give you more FPS, it will not improve your system performance really at all unless you utilize it.

If you are going to do video/audio editing then yeah a RAID 0 could improve performance when handling large chunks of raw data. For internet/office/gaming use RAID 0 pretty much does nothing.

Running RAID 0 also puts you are higher system failure rate, since if one drive fails, the whole array fails and all is lost.

RAID 0 is called striping the drives, and you are correct. Both drives act as one single volume with both of them simultaniously reading/writing to both drives at the same time. Data is split amongst those drives.

RAID 1 is mirrored, which slows performance since both drives have to write the same data to the same drive individually, however if one crashes you can rebuild the RAID 1 off the cloned drive with the RAID utility.

RAID 5 is very similiar to RAID 1 except its mostly found in server solutions for storing and manipulating huge amounts of data, databases, etc.

In the last benchmark I read (which was like 2 years ago) 1x 74gig 10krpm raptor was fatser than 2x 36gig 10k rapor @ RAID 0 because the 74 gig has a faster seek time than the 36 gigs. This was of course benched against office/internet/gaming usage. They weren't rendering a movie in maya or editing a TV show on this computer, it was normal use. If that were the case the RAID would help perfomance.
