vst plugins and content in sonar x1 expanded

I have rebuilt my installation from one ssd to a 500gb raid with 2 wildfire ssd. I have also added to western digital enterprise 10000 rpm drives which are 4 times faster than my original drive secondary drive.
 
It might be subjective but should i install the vst plugins and the content away from the c: drive and if so how do i do that.
 
As a novice I always found sonar difficult on installation and thats with default directories.
 
If i get the sequence wrong then plugins are just not found.
 
I have the producer version along with rapture, z3 v2 and dimension pro as a purchased version as well.
 
advice on where and how would be great so i get the utmost from my system.
 
Quad core intel 950
8gb ddr2
64 bit win 7
2 x wildfire 240gb ssd c: drive
2 x western digital raptor raid 0 f:drive
1 x seagate 1.5 terra hardrive d: drive (this is an appalling drive, seems to hibernate on its own or just plain drowsy)
