hi, A new thread, anyone got a new 11ac TC and can report the file accessing R/W rate? steps described by Raima: 1. Connect your mac to your TC via a cat 5/6 cable. 2. Install Black Magic Disk Test 3. Connect to your TC Drive on your Mac 4. open up Black Magic Disk Test on your mac, and select the target as the TC 5. Run the tests and report back with the results or, can simply read or write a big file on TC and watch the cpying rate. New TC and AE have good processor from broadcom they should have big performance improvement than older generations.
