Which disk?

Hi,

I am new to VST instruments and just acquired the Grand 3 for using it with Cubase 6.
I have two SATA internal disks (besides the one that runs Windows 7 64bit OS and all the programs ) let´s call them A and B.
Both are 7200 RPM and both are big enough to house the Grand 3 Samples and more, BUT A has a 2 MB cache and B has a 16 Mb Cache so the question is:
Which one should I use for the VST samples and which one just for the Audio samples?

Thanks

You should stream from B.

Thank you for your kind reply, that is what I supposed and I already installed all the streaming files on Disk B.
