I have 4 Seagate 500gb 7200.12 ST3500418as CC46fw running as Raid 0. In Intel Matrix Console, should I enable or disable " volume write-back cache "? I have heard this should only be enabled for RAid 5. Thanks in advance for any help or info.

This is with write-back cache disabled:

and with write-back cache enabled:

Looks like with it enabled the max speeds are higher and fluctuate but average speeds is slower

Use the enabled option. I think that average speed is smaller because of the fluctuates. But you should look on the maximum speed - in case of const writing operation it will bring you more performance.
