Best configuration for RAID 0 settings

[Energinerbuzzy]

I have been testing to RAID 0 arrays on my computer trying to figure out which one will be the faster set.
I have two SATA2 WD 160gig drives
And two SATA2 Seagate 320gig drives witht (Perpandicular recording tech).
I have tested the WD's with several different cache settings from 8k to 128
And so far these are the average results using HD Tach

WD's burst speed is around 295, average speed is 125, random access is 13.1 and CPU utilitasation is 3% to 6% (cache size only seemed to matter on the CPU)

The Seagates I thought would fair better but i'm not sure. Burst speed is around 190 average speed is around 135, Random access is 13.3 and CPU 3% to 6%
again the cache size seemed to only make a noticable difference on the CPU usage.

I could use some advice as I don't realy know what is better , Average speed or Burst speed. And should the random access times be so high?

I use this rig mainly for gaming and not for mass storage.

Thanks for looking.......

I think average speed is what you want to go with. it will help when loading programs, games etc. Random access is what actually makes the computer think faster. but for noticeable performance stick with the higher average speed.
