Hard Drive Speed in Network Environment

I am working on getting a high end workstation quote from our SolidWorks reseller based on information I have read out here so far.  They are telling us that the hard drive speed is less important since we are saving all our files to network drives.  I assume the speed will still affect the performance of the paging file.  Do you think it is still worth the extra money for faster drives?
