Thanks a lot for your reply.
Im using ProRes 422 files, usually XML’ed from FCP. The external does have a fan.
The sound is, as you described, like a very fast “chunking”, however when working in after effects its much more frequent than in FCP. There is also a beep-like high pitched humming sound.
The workflow seems slower in comparison with the times when I was working from a local hard drive. The filters like denoiser are handled much slower. And the rendering process seems to be slower, with G-Raid emitting high pitched humming and chunking sounds.
Im just wondering whether my workflow of XML’ing from Final Cut to AFX while keeping all of the footage on my external is a proper way to do this.
Thanks.
