We operate PPro on a NetApp NAS with a dedicated All-Flash-Drive-Array for caching. All Premiere installations point to the same directory for the cache files, while each workstation uses its own cache db on an internal ssd. While this works fine in general, every now and then PPro automatically resets the chache file path to its defaults without any notice. Please make the user's choice a permanet one. If the location is not available, PPro sould issue a warning message in that case (eg. if the network is not ready for any reason.)
Also, we would very much appreciate if there was a shared coache db for all our editing suites to speed up operation.
