A New Look!
Enhanced dust prevention, cooling and stability.
The AS40 series diamond-cut exterior has a magnetic cover for easy access to hard drives within. Its front panel hexagonal design creates a lightweight, yet strong frame for added durability and protection. The AS40 series also comes with a better cooling design, allowing for better airflow, allowing for higher longevity and lower failure rates.
Toolfree Installation
ASUSTOR’s AS40 series introduces its new tool-free caddies as a way to simplify installation of hard drives. Each NAS comes included with brackets to install the drive easily. On the AS4000 series, hot-swapping of hard drives is supported, allowing you to change hard drives easily without powering down the NAS.
PC-less Software Installation
Mobile installation with AiMaster takes only 3 steps! Finding your NAS, system initialization and installation, power management, ADM firmware updates, system information and more are all available from the convenience of your mobile device at any time.
Dual Core 64bit CPU and DDR4 RAM
The Marvell 64bit CPU found inside the AS40 series contains two cores clocked at 1.6Ghz powered by the ARM Cortex A72 microarchitecture. Compared with the Cortex-A15 core, the Cortex-A72 is three and a half times faster while providing seventy-five percent reduced power. The AS40 series also supports DDR4 RAM soldered onto the motherboard, providing even faster bandwidth and lower power consumption than DDR3.
Unlimited potential
10gbps speeds
ASUSTOR’s AS40 series of NAS are the first line of consumer NAS made by ASUSTOR to feature 10gbps of bandwidth over Ethernet. Our 10gbps Ethernet port uses RJ45 which are different from SFP+ as it is more accessible to consumers, and flexible with different Ethernet speeds and standards.
Up to 3gbps of aggregated performance
The AS40 series of NAS can provide up to 3gbps of aggregated performance. Even without 10gbps switch or router, connecting all Ethernet ports (two gigabit, one 10gb) of the AS40 series simultaneously and enabling Link Aggregation feature can combines 3 gigabit network connections into one.
Brand New Interface Design Elements and Flexible Use of Desktop Space
ADM 3.0 provides a flexibly designed desktop layout that can provide an optimal configuration based on the display resolution. Furthermore, convenient App organization provided by the grouping function allows users to experience management that is very much like a tablet device.
Ultra-quiet Operation
The AS40 series devices produce only 19 decibels of noise during system standby, equivalent to the almost inaudible sound of a pin drop. During system operation, only 32 decibels of noise is produced, equivalent to the hushed tones of a quiet library, allowing the AS40 series devices to seamlessly and comfortably integrate into any living environment.
24/7 reliability and durability
All ASUSTOR NAS are designed for and are suitable for 24/7 use. ASUSTOR NAS devices have also undergone rigorous tests, such as drop tests and burn tests to test durability in extreme conditions. Heatsinks were added to sensitive components to dissipate heat, helping to maintain the longevity of the device.
Save power to save money
ASUSTOR NAS products are designed and developed around ecologically friendly concepts. When in use, our devices consume far less power than the average computer or server. Furthermore, our advanced power control features allow you to more efficiently manage your NAS device and hard drives. This lowers your electric bill and prolongs the lifespan of your hard drives all at the same time. While in disk hibernation, the AS4002T consumes only 12.7 W of power. Under normal operating conditions it still only consumes 19.5 W of power.
Cross-Platform Multi-User Access
The ASUSTOR NAS provides seamless cross-platform and multi-user access, allowing you to easily connect to your NAS from Windows, Mac OS X or Unix-like operating systems no matter if you are using a PC, notebook, tablet or smartphone.
