Overview:


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.

Simply Plug it in

*NAS series supporting expansion of up to 3 units: AS31/32/50/51/52/53/61/62/63/64/70 (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.

Safety Bracket for Secure Connections

The security bracket and mounting hole design allow the AS6004U and USB cable to be connected securely without having to worry about disconnections.

Secure Disk Tray Lock Design

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., MyArchive).

Smart Power Saving

The AS6004U has a power sync mechanism that syncs it with the NAS's operation status. When the NAS enters sleep mode or powers off, the AS6004U will enter into standby mode. When the NAS resumes normal operation, the AS6004U will resume mounting. This function works to help users save significant power.

Smart Power Saving

Smart Fan Temperature Control

Under heavy loading and operations, the system internal temperature will increase. The AS6004U utilizes fans with a wide speed range that support a temperature control function combined with a smart speed mechanism. When the system load and temperature increases, the fans will automatically increase their speed to cool the device allowing the system to maintain a suitable operation temperature, providing stable performance and service.

*Temperature will vary depending on the number hard disks installed and the brand.

*The AS6004U supports Single Disk, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10 volumes
