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 64bit architecture supports up to 16TB on a single volume. 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. Performance figures are achieved in the ASUSTOR lab using state of the art client computers under optimized network settings, and could vary in different environments. Ordinary desktop or notebook computers may be unable to reproduce these figures.

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.
