RAID 0 Performance and Games
(Click here to view the original thread with full colors/images)

Atomicfire.net has an article up on how RAID 0 affects your gaming performance and load times.
Well, that speaks volumes doesn’t it? When combined, that makes an average of only a 12.5% performance increase! I actually ran these tests multiple times to make sure the numbers were right. While a 12.5% percent (2-6 seconds faster) may be incentive enough for a select few of you to get a RAID 0 (or any of its variants). I personally cannot justify the extra cost for so little performance. The performance is so low that a game patch which optimizes loading times may speed it up by 5 seconds anyway. The Synthetic benchmarks were totally off base in regards to the loading times in games.
Furthermore to get any kind of long-term storage reliability, you will need to invest in two more hard drives and go with a RAID 0+1 Array. Let’s face it hard drives fail. It is a simple fact of life. The hard drive you have inside your computer right now is *going* to crash, it’s only a matter of time. Having two drives linked together, as having them in a RAID 0 setup would do. Creates, quite literally, twice the chance that it will fail and destroy the data. While data lost in such a way can still be recovered with the aid of professional disk recovery companies. It is rather expensive to have it done, further adding to the overall cost.
That being said, RAID arrays still has dominance when it comes to professional multimedia applications. It offers *much* faster I/O performance then a stand alone drive. The advent of SATA could be a herald of some technology breakthrough looming in the not-too-distant future. When you add Native Command Queuing into the mix the performance only increases.

NCQ is looking good. I'm thinking about getting one of those SATA drives when I upgrade to an nForce4 board

Im going RAID on my next system anyways. Max performance is what Im going for. And I want the transfer from hard drive to 2gb of ram to be as fast as possible.
What about 10,000 rpm SATA drives? Thats what I plan on RAID'ing with.

That's currently the most popular config. A pair of WD Raptors.

then why would you bother with mere sata raid? it wont do much over a single sata drive. you want scsi raid.

2x10000rpm drives wont be much over 1x10000 rpm drive?
I dont want SCSI because its loud, and more expensive.

nope. read and write times drop, thats it. for a whopping 12.5% performance increase during loading for games. doesnt affect the rest of the game. you did read the article, right?

didnt you just say you want maximum performance? i mean, if youre willing to shell out $200 to increase your game loading times by 12%, with no advantage during normal operation or gameplay, i wouldnt think scsi drives cost would bother you.

Uh...The drives they used are 7200rpm SATA drives, not 10k.
