The 10GbE NAS Storage Solution.
Built with only two speeds, FAST and EXTREME.

• ASUS motherboard quality
• Marvell 1.6GHz CPU
• 2GB of DDR4 RAM at 2400Mhz, fast and efficient.
• Dual gigabit Ethernet with the addition of a 10gbE port.
• All new diamond cut exterior
• Magnetic dust-proof cover
• Supports four hot-swappable HDDs
• Screwless, Toolfree installation
• Hot-swappable
• 3 year warranty, best in class

• 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.

  Tool-free 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 AS40 series, hot-swapping of hard drives is supported, allowing you to change hard drives easily without powering down the NAS.

  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.

  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.
