Review on Asustor AS6004U Storage Capacity Expander by Dennis Goozmer

Since I have an AS6510T main NAS, I added a separate Asustor AS6004U (4 Bay) USB expansion device to test the MyBackup feature, which seems to be working fine. I would like Asustor to hopefully address the device: 1) When using the night mode feature on the main AS6510T NAS, the LEDs mostly go out as expected with the orange LED flashing intermittently, however the LEDs on the AS6004U unit remain on which, I believe also turns off when connected to an AS6510T. 4) The device has tool-free drive bays.
