Product description

The AS6004U utilizes a USB 3.0 connection cable. Simply plug it into any ASUSTOR NAS to complete hardware expansion! Depending on the model, ASUSTOR NAS devices can simultaneously connect up to 3 AS6004U units, satisfying the high capacity storage demands of enterprise users. The security bracket and mounting hole design allow the AS6004U and USB cable to be connected securely without having to worry about disconnections. In order to help users avoid accidentally pushing disk tray buttons and releasing hard disks during operation, ASUSTOR has added a new lock mechanism to its hard disk trays. The lock's flat-head design ensures that users will not need any special keys or tools to unlock it, only a simple flat-head screw driver. The new disks trays can be used with all ASUSTOR NAS devices, providing an additional layer of security for applications requiring the frequent swapping of hard disks (e.g., My Archive).

4.0 out of 5 stars AS6004U - actually work, as described.
Reviewed in the United States on 21 August 2020
As I have the AS6510T main NAS unit, I added a separate Asustor USB Expansion unit AS6004U (4 bays) to test the Myback up feature, which seemed to work okay.

I only have one concern, that I would like Asustor to hopefully address with the unit:
1) While utilizing the Night Mode function on the AS6510T main NAS unit, the LEDs do mostly go off as expected, with a periodic glowing of an Orange LED, however, the LEDs remain on on the AS6004U unit, which I would expect to go off as well, when connected to the AS6510T unit.
4) The unit has tool-less drive bay trays.
