"The installation of both hardware and firmware update was quite simple...The web interface works quite well; it's just shame that they have not got it to fill the entire screen, but this will come in a future firmware update. There was never difficult to find the desired functionality in GUI. Overall performance is at the top of the scale...”

"Overall, the Thecus N0503 ComboNAS offers SOHO users a fully maximized NAS device regardless of the size of your hard disk drives. Its three 3.5” hard disk drives are perfect for high capacity storage. However, if your storage needs are small but energy efficiency is an issue you can switch to 2.5TB worth of 2.5” hard disk drives or if performance is what you’re looking for, then the 2.5” bay options also support solid state drives as well for even better speed and reliability."

 Ever the innovator, Thecus® Technology has racked up an impressive number of firsts. In 2005, Thecus® introduced the world’s first DAS device with eSATA support, enabling file transfers of up to 3Gb/s. With the N3200 in 2007, Thecus® brought the security of RAID 5 to a home NAS. Today, Thecus® is pleased to reveal the world’s first NAS device with the ability to accommodate both 2.5” and 3.5” hard disks – the N0503.

One look at the N0503 tells you it’s different. Using its special combo hard disk bays, the N0503 can actually support up to five 2.5” hard disks or three 3.5” hard disks. Fill the N0503 with three 3.5” hard disks and the N0503 is a high-performance three-bay NAS with up to 6TB of storage capacity. Equip the N0503 with five 2.5” hard disks, and you have a five-bay NAS unit that offers lower power consumption and noise. With dual form-factor hard disk support, users are given unparalleled flexibility with the N0503.

The N0503 also offers quick system response and file transfer capabilities with its powerful Intel® ATOM CPU and dual Gigabit Ethernet ports. Multiple RAID modes including RAID 0, 1, 5, 6, and JBOD are selectable, and auto volume rebuildhot swap and hot spare capabilities mean maximum data reliability. The N0503 also comes with advanced data protection in the form of disk array roaming and Nsync – Thecus’ remote replication utility. Speedy and secure, the N0503 makes a perfect place to house your digital data.

But storing and securing data is only part of the equation. The N0503 also comes with a slew of advanced features that really take NAS storage to the next level of usability and convenience. With support for an iTunes server, a photo web server, and uPnP AV streaming, the N0503 is an ideal media hub for the digital home. Connect the N0503 to your home network and stream music and movies throughout your house. With the built-in IP camera surveillance server, you can use the N0503 to keep tabs on your home or office for enhanced security, and with included download manager, you can download BT and eMule files during off-peak hours to maximize your available bandwidth and reserve peak hours for other more critical tasks. To top it all off, a slick LCD panel notifies you of critical system information at a glance and a completely revamped AJAX-based web GUI makes the N0503 easier to use than ever.

Equipped with dual hard disk support, advanced data security and strong performance, Thecus® has once again changed the rules of NAS storage with the N0503.

“We knew the N0503 would turn a lot of heads when we released it, and with good reason,” notes Thecus General Manager Florence Shih. “By thinking outside the box, Thecus® has proven once again its spirit of creativity and innovation with the N0503 - the most flexible NAS storage device on the market.”
