Crafted for ultra-quiet and cool operation
We have meticulously designed a specialized cooling system for this high performance NAS. A single extra-large fan (different from common add-on fans) and dedicated heat pipes work with the ingeniously designed disk tray vents to allow air to flow from the front to the back of the device, effectively cooling the CPU and hard disks. Furthermore, our ADM software comes with an automatic fan control mechanism that effectively controls the fan rotation speed, significantly lowering any noise produced and allowing the NAS to operate at noise levels lower than any library.

Expand your storage space
A professional grade NAS needs to be equipped with a diverse array of expansion functionality. In addition to the 4 drive bays, we have also included 2 USB 2.0 ports, 3 USB 3.0 ports and 2 eSATA ports, allowing you to create a tailored storage space for both your work and entertainment needs.

Extreme Multimedia Playback
No matter if it's 4K or 10bit, XBMC 13 paired with the Intel Core i3 dual-core processor's powerful built-in graphics engine gives you the ability to play any video files with ease. Get ready to enjoy brilliant and flawless images on ultra high resolution monitors.

Additionally, you can also further add a surround sound amplifier to create an unprecedented high definition multi-channel listening experience. Imagine watching your favorite racing movie and being immersed in the roar of the engines. Feel the thrill and the sense of speed as you listen to the sounds of cars whizzing by. Prepare for an unparalleled entertainment experience that will have you on the edge of your seat.

Even More Reliable After-Sales Service
ASUSTOR has extended the warranty period on all of its products to three years, continuing to make customer service a huge priority. It is ASUSTOR's mission to continue to provide its customers with products of the highest quality along with only the most reliable and attentive after-sales service and technical support.

A Surge in Data Transfer Performance
ADM 2.3 supports SMB 2.0 which reduces the burden of network traffic on the NAS while simultaneously providing greater data transfer capacity.In the ASUSTOR testing environment, SMB 2.0 was found to increase Windows networking performance by 30%-50%*. SMB 2.0 also significantly increases the number of concurrent Windows client connections and simultaneously open files, making ADM 2.3 even more suitable for large-scale Microsoft network environments.

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).
