A couple questions about Raid0

[UT-Jackal]

I am building a new computer and basically all i want to know is if there is any positive/negative aspects of running Raid0. Should i just continue to run a single Sata drive alone or go with Raid0. I do have two back up drives, so that wouldn't be a problem. I know this is a newb question, but i know nothing about Raid0, 1, etc.

Thanks

I researched this myself reciently but I didnt ask anything, just spent bout 30min searching here and google. What I found was, and i may be completely wrong but this is what I believe.

Raid 0 will will provide some speed increase but depending on who's post you read that increase was on average only about 15%-20% with some people stating that if your building a gaming machine you would be better off getting a single high preformance drive.


As for negatives the only bad thing I could find is 2 hard drives increase the posibility of failure.

When you run raid 0 with 3 or more drives your throughput whops even the fastest single drive (not counting scsi or sas). Seek times go down a little but overall you will see a good increase in performance.

Also, you also may have a harder time fixing something if your OS breaks, since many linux live CDs (typically used for this sort fo thing) do not have drivers for most raid controllers.

raid 0 has its place depending on the application but it's usually not worth it for regular user. Sure raid0 will beat single drive in str (sequential transfer rate) but raid0 doesn't improve seek times and a lot of games load data from multiple files so str performance doesn't help them
For gaming you're usually better off with single good drive like raptor.
