  • 1Description

The N4520 4-Bay NAS Server from Thecus is designed to offer a revolutionary experience to the NAS industry. It utilizes the current Intel Atom processor with 2GB RAM. In addition, SuperSpeed USB 3.0 fosters quick transfers, HDMI output is convenient for multimedia playback and McAfee Antivirus protection keeps your NAS operating smoothly. Innovative technologies have been utilized to develop the new N4520 NAS to serve one single purpose: improve your experience and satisfaction.

The next-generation Intel Atom CE media processor CE5315 is designed to manage multitasking like multimedia playback and data backup without affecting performance. This significantly changes your experience as NAS appliances are becoming optional to mandatory. Furthermore, the new Intel Atom processor provides superior performance and efficiency with its System-on-Chip (SoC) platform. It provides a true multi-user NAS environment with web hosting, data backup, data encryption, application serving, RAID 0, 1, JBOD (N2520) and RAID 0, 1, 5, 6, 10, JBOD (N4520)volumes and multimedia playback.

A noteworthy feature of the new operating system includes auto firmware and module update. You don't have to go online to check whether your NAS has the latest firmware and modules. A quick look at the UI and the simple press of a button is all you need to keep your NAS updated. Most importantly, ThecusOS 6 promotes a faster, smoother and more fluid transition during NAS management.

The new Thecus N4520 is the ultimate home and SMB NAS for any user who manages daily data backups, personal cloud to multimedia playback purposes. The easy 5 minute installation contributes to the phrase "plug and play" in addition to the easy remote NAS access via DDNS. Furthermore, the client utility feature, also known as "Intelligent NAS" offers a revolutionary experience to manage your Thecus NAS without the need of web browser. As networking storage technology is evolving quickly, energy efficiency is always a consideration. The Thecus N4520 paired with the current Intel Atom SoC chip offers excellent performance while conserving energy. ThecusOS 6 and Auto Flashback Photo Gallery are remarkable updates which add to your experience.

Ultra Energy Efficient
Thecus utilizes the current Intel Atom processor built on a System-on-Chip (SoC) platform. The chip offers a myriad of works built into one; such as processor, graphics, memory and so on. This innovative technology paired with the Thecus N4520 offers superb energy efficiency. The server also offers low power consumption of x 86 NAS, 9W idle/14W load and over 50% power savings. Furthermore, noise levels are kept to a minimum at 20 dB. This combination of Intel Atom processor and Thecus NAS can be summed up as "pure performance, ultra energy efficient."
5 Minute Complete Installation
The server is designed with ease in mind; it is easy enough for anyone to set up. Overlook the several steps that are usually associated with setting up NAS appliances. Simply plug the power supply, insert the Ethernet cable, boot up the N4520 and setup will be completed within 5 minutes. This breakthrough feature truly makes this a plug-and-play NAS.
Quick NAS Accessibility Using Client Utility
The client utility feature, better known as "Intelligent NAS," offers a unique way to access your NAS without the need to go through web browsers. This powerful utility can directly be installed on your computer and auto-Samba your NAS, thus automatically giving you access to designated folders. Browse all your photos, see statistics about your stored data, monitor your NAS (copy/download/log activity), personalize, manage and share files, all this in one easy-to-use application.
Easy Connection Through DDNS
Have easy access to your NAS via Dynamic DNS (DDNS). This allows you to allocate and access your NAS files via the Internet remotely. Since IP digits are often difficult to remember, domain names are utilized to make NAS management much more convenient. When the IP address is changed, the DDNS server will automatically adjust the IP address to make sure that remote access is always available. In short, DDNS provides convenient remote Internet access to your Thecus N4520 by utilizing domain names instead of IP digits.
Personal Cloud
The server can easily be set up as your personal cloud. You can now access all your files stored in your NAS via any mobile device synced to the NAS network. The N4250 offers up to 16TB of storage capacity with a large amount of cloud storage. In addition, cloud service providers such as Dropbox, ElephantDrive and Amazon S3 are fully compatible. Whether you are backing up sensitive data to your personal cloud or streaming movies and music from your NAS, the server offers easy personal cloud access.
HDMI Output for Multimedia Playback
With the easy-to-use local display module, simply plug a screen via an HDMI connection; you will not require a computer anymore to monitor your NAS. Local display via HDMI makes things much more convenient, directly attach keyboard and mouse or sync your mobile device to start data management. It is ideal for small/medium business users who need to show presentations or home users who wish to display multimedia on their HDTV. Whether it is music, photos or videos, the server is capable to display multiple formats via HDMI multimedia playback.
Auto Flashback Photo Gallery
A new feature that Thecus has integrated in theN4520 model is the Auto Flashback Photo Gallery. When the user utilizes the client utility feature, they will be presented photos from the past, hence flashback. For example, if the current date is "Feb xx, xxxx," Auto Flashback Gallery will automatically display photos of the same date but different year. If a photo of that date is absent, other photos will simply take its place.
Data Guard
Data Guard backup solution is the ultimate software that provides both local and remote parts. Currently, data is backed up across RAID volumes, external USB drives and eSATA. In addition, Data Guard uses innovative technology to sync data across the network to other NAS and servers. More importantly, Data Guard makes managing NAS user-friendly and convenient.
Data Burn
NAS data can now be burned directly to CD, DVD and Blu-ray discs with Data Burn. This hassle-free module makes burning data to a disk effortless. In addition, burning ISO image file is also supported. Whether you are managing audio, media or essential files, Data Burn copies information fast while significantly reducing waiting time. The process of burning file to disk is now easy and smooth with Data Burn module.
Innovative hardware of Thecus helps prevent failures. Adding an antivirus to the already comprehensive software bundle provides the necessary software protection by scanning the files on your NAS and defending it against possible threats. You can get the benefit of McAfee's powerful software on your NAS entirely for free.
USB 3.0 Connectivity
The next generation of connectivity is here with speeds 10 x faster than USB 2.0. Whether connecting digital cameras and smartphones, backing up large external hard drives or extending the capacity of your NAS, USB 3.0 ensures it's done in no time at up to 5 Gb/s. Furthermore, it is backwards compatible with USB 2.0 and USB 1.1 devices, providing a combination of speed and universal access.
Acronis True Image
Acronis advanced backup software comes with a slick interface, user-friendly design and comprehensive features to keep your data safe. Back up all your data with one-click protection or pick and choose only your most important files.

Should a hard drive malfunction occur, changing the drive is simple, thanks to online RAID migration and expansion, hot spare and auto rebuild capabilities of the NAS.
iSCSI Thin-Provisioning
Connect through iSCSI for the fastest data transfer speeds available and eliminate disk space wastage with thin-provisioning's flexible storage functionality.
iOS/Android Connectivity
In the modern world, nothing is as important as reaching your data from anywhere. With T-OnTheGo and the Thecus Dashboard, you can manage your NAS and upload to and download/stream from your NAS using an iOS or Android device on the go.
