Thecus is proud to present itself as a technological innovator. Once again, Thecus releases an all new 5-bay N5550 server to lead the competition. The past proves merit: link aggregation, LCM display, USB 3.0, multi RAID functions and so on. Impressive technologies have been used to develop the new N5550 NAS to serve one single purpose: improve user experience and satisfaction.

Intel Atom CPU: silent power

Intel Atom CPUs are designed to work without fans. This will dramatically reduce NAS noise and power consumption.

Associated with 2GB of DDR3, Intel Atom CPUs will provide much better performance. Don’t be restricted to a 4-bay NAS, bring it up a notch, Thecus N5550 is available and boosts the best performance with a great price, without entering larger bay units. Multi-users environment, web hosting, intense backup, data encryption, application serving, heavy RAID computations, and HD multimedia streaming: welcome to the world of smooth multi-tasking!

McAfee Antivirus: preventing possible threats

The N5550 NAS is McAfee antivirus embedded meaning that users can have confidence that their sensitive data will be protected by the most advanced antivirus software, McAfee.

USB 3.0: from optional to mandatory

Thecus started integrating USB 3.0 more than one year ago, enabling this blazing fast protocol on most storage devices by embedding a PCI-e slot. On popular demand, future NAS will equip at least one port for USB 3.0 transfer rates of 10 times faster than USB 2.0.

HDMI, VGA and Audio out: removing the middle man

After installing the proper module, simply plug a screen by the use of HDMI output, you don’t even need a computer anymore to check on your NAS! Local display via HDMI makes things that much more convenient, directly attach keyboard and mouse to start data management.

The N5550 also supports VGA output for attaching traditional televisions, projectors and monitors. VGA output makes this 5-bay NAS convenient to display presentation or media files when HDMI is not on hand.

To add, users can attach speakers directly to the N5550 NAS to play audio files. With audio out, managing media and audio files is simple; attach the speaker plug to audio out and you’re set to go!

Ideal for small installations and/or mobile users, these features are designed to lower the total cost of ownership of your network architecture.


  • newegg Antivirus Thecus’ innovative hardware helps prevent failures. But sometimes you have to protect the NAS against itself. Adding an antivirus to the already comprehensive software bundle will provide the necessary software protection by scanning the files on your NAS and defending it against possible threats. McAfee is the world’s largest dedicated security technology company and shares Thecus’ spirit of dedication and quality. By establishing a strong partnership with them, Thecus will allow users the benefit of McAfee’s powerful software on their NAS entirely for free.
  • newegg Cloud Backup The private and public clouds meet with Thecus’ new DropBox, Amazon S3 and ElephantDrive cloud backup functionality! Guard your data with RAID at home and an additional level of protection in the Cloud. Just drag and drop files into the folder on your NAS and access them on any computer or mobile device with DropBox, Amazon S3 or ElephantDrive.
  • newegg Multiple RAID When it comes to data management, Thecus NAS truly let you have it your way. Create multiple RAID volumes each supporting different RAID modes including RAID 0, 1, 5, 6, 10 and JBOD for your own balance of performance and data protection. Should a hard drive malfunction occur, changing one is simple thanks to online RAID migration and expansion, hot spare, and auto rebuild.
  • newegg iSCSI Thin-Provisioning Get the most out of your storage space with the extreme speed of iSCSI and the efficiency of iSCSI thin provisioning. Connect through iSCSI for the fastest data transfer speeds available and make wasted disk space a thing of the past with thin provisioning's flexible storage functionality.
  • newegg iOS/Android Connectivity In the modern world, nothing is as important as reaching your data from anywhere. With ThecusShare 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.
  • newegg User Quotas Divide the massive storage of a Thecus NAS among multiple users. Whether there are two users or 100, user quotas make it easy to divvy up and manage disk space.
