I know the camera raw cache should be on fastest disk for best performance.
I was wondering if it should be on the same drive as the catalog or does it not matter?
I question whether or not you will be able to detect a difference. My Camera Raw cache is on the same drive with my Lightroom program and catalog. But I have installed a SSD drive. Once Lightroom is loaded and running, I haven't been able to determine any difference in performance. The program does load faster, but once it is running I haven't been able to see any real difference.
It is correct that the Camera Raw cache should be on the fastest drive.
And it should not be an issue if you keep both on the same drive.
Thanks to all.
