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 two hot-swappable HDDs- Screwless, Toolfree installation- Hot-swappableDual Core 64bit CPU and DDR4 RAMThe 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 potential10gbps speedsASUSTOR’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.Ultra-quiet OperationThe 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.
