best configuration of my drives??

hello all,
  windows 7 running on dell xps 630i with 2 hard drives and 6gb ram
    a western dig. ide drive of 80gb and a western dig. sata drive of 640gb
     (the sata drive appears much faster, at least throughput)

   i currently have these configured as the small ide for my os
     and the larger, faster sata for my audio drive

   what cache settings should i use for these? under device manager and policies should i uncheck both settings?
     or check both?
   
    i've read for sata you check both options and on other sites it says to uncheck both??

   also, is it best to uncheck index under properties when you right-click the drive?

   any suggestions on the virtual memory page file?  some say to set one up on the audio drive and some say disable it completely

   thanks for any input!

Under "system performance" it is best to set your machine to pander to "applications" rather than system.  Modern Windows can do it for you, but it takes up machine resources. 

I would still let the drives index - for when you have a "folders panel" seen inside an application (such as most multi-track recording programs) that you are running, it needs to have all files ready to use. Otherwise you will have to wait for your machine to look for it.  The temporary index file that "seeks" during startup only takes a tiny amount or resources, and allows searching to be very quick.  Indexing happens during downtime, and your programs and actions take percedence.

For the paging file, if you have, say 4GB of RAM, then the best preformance level is to set the paging memory to double the RAM size.
