Hard drive questions, using 3 disk total, 1 system 1raid 0
 

I have a win7 x64 and have 3 disk total, 1 disk is for programs/OS, the other 2 are Raid 0 1.5gb 3.0gb total.

Question is about the Raid, Should I only have my current video project(s) loaded on that disk for optimal speed?

Because as of now I have 2GB of "other" files and "437GB of current video projects.

So should I find another place for the "other" files, and just have current video projects on the RAID0 ?
