Do you mean the prerendered files folder? Store it wherever there's enough room. I have my OS drive and a data drive separate and the data is larger. I put prerendered on the data drive as it's more spacious. I move media to the data drive for editing and back to HDDs for permanent storage.

Exactly. My new machine has a programs Drive , C, an audio Drive and a samples Drive . Thank you Roger.

Vegas Pro's installation should ideally be on the same drive as the OS (usually the C drive), but .veg files can be stored on any drive (mine are on the D drive) and media can also be on any drive. IMO, the best arrangement is to have VP installed on the C drive as with the OS, project files and media can be on the D (or other) drive and yet another drive used as the target for rendering. Keeping the various processes on separate drives means that the drives 'seeking' processes are separated for different processes (e.g. OS, media, rendering).

Thanks. I do have a third Drive for samples. You would suggest putting the rendering on that one? I have the project files and media on the audio Drive and the program itself on C drive with the operating system. The third one, the sample drive, has got a bunch of Native Instruments samples.

It likely doesn't matter. Assuming you are talking SSDs of some variety it's unlikely hard disk throughput will ever be the bottleneck. If you're working with uncompressed raw video, consider m2 SSDs.

I recently got an unreasonably fast SSD (read/write above 6000MB/s) and watching it while I work in Vegas have yet to see activity above a few hundred MB/s.
