I especially liked the videos reviewing the new Asustor LockStore NAS AS7110T and the AS6510T.
Have a question about these new units….can drive expansion units be added?
Yes, you can surely use AS6004U. It connects via USB allowing you add four more drives to your existing NAS.
*NAS series supporting expansion of up to 3 units: AS31/32/50/51/61/62/63/64/70 (other series are only able to expand up to 2 units)
*Please use the NAS’s USB 3.0 port to connect the AS6004U
*Please use the ASUSTOR provided USB 3.0 cable
*If 70 series models have 12 devices plugged into USB 3.0 (1 hard disk = 1 device), the other USB ports will not be able to be used.
*On AS7012R devices, if 3 USB expansion units are plugged in (12 hard disks), then only one e-SATA port can be used.
Simply Plug it in
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.
