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.
*NAS series supporting expansion of up to 3 units:
AS31/32/50/51/52/53/61/62/63/64/65/70 Series
(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.

Data Protection Starts with Storage
ASUSTOR understands that your data is priceless,
therefore ASUSTOR NAS provides different RAID
Volume options, giving your data various levels of
protection from the moment it is first stored on the
NAS. We recommend you plan your storage
protection based on your NAS model and number of
hard disks. Data protection has never been so simple.

Safety Bracket for Secure Connections
Secure Disk Tray Lock Design
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., 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.
Flexible Storage Expansion and Backup
In addition to providing an economical high capacity storage
space, the AS6004U also supports ASUSTOR's MyArchive
cold backup technology. This allows users to create
removable storage archives at any time, and backup
important data to them.

Smart Fan Temperature Control
The AS6004U features 4 hot swappable disk bays and is
compatible with largest hard disks on the market. It supports
RAID* and AES 256-bit encryption, providing optimal data
protection mechanisms.
*The AS6004U supports Single Disk, JBOD, RAID 0, RAID 1,
RAID 5, RAID 6, RAID 10 volumes
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.
