Even in the end, the review continued its positive outlook. “I have always looked at their products as an affordable alternative to the bigger NAS companies. Thecus NAS usually distinguish themselves in the marketplace with quality and price-ratio, however it was great to test this NAS where the emphasis was on performance. 
Media: TweakTown | Country: USA
“Overall, with the launch of OS 7 and many of the new features including BTRFS support, the N5810 NAS is more attractive now than ever before. Adding to this is SSD caching technology that has been greatly improved, along with the integrated file server and an entire platform that has been designed for 64-bit architecture. The N5810 is one of the top five-bay appliances on the market today. The build quality is top notch including the internal components, every IC in this appliance comes from Intel including the SoC, NICs, and SATA controller.”
Media: ZeDen | Country: France
“The N5810 NAS is therefore a high-end product, with the specifications and performance justifying its price, especially in comparison to other 5 bay NAS of its competitors. Version 7 of Thecus OS allows the Thecus brand to catch up to the current industry leaders. Consisting of solid components, the performance is there and with the design and ergonomics both being engaging. What more do you need?”

As video makers or any other professional working with multimedia files know that managing data is an essential task.“This device is very useful especially if your work generates tons of data and you need to easily access it.” Using traditional storage devices such as external drives can cause many issues. “NAS servers such as the N5810PRO make life much easier then when using external hard drives.”
Media: Guru 3D | Country: USA

“A NAS is not just a file-server anymore, these are fully fledged file serving servers with a plethora of applications and functionality. The Thecus N5810 with the new updated software definitely will be one of the more versatile NAS units available on the market. We like what we saw for hardware, software and functionality.The overall performance is really good, it is Gigabyte Ethernet compatible. At a 500 EURO/USD marker it is not cheap though we feel the price is fair for what you get, and you are receiving a SOHO server. Right, the Thecus N5810 we can recommend for the SOHO and consumer side of the market, it is an incredibly fun and handy NAS with excellent performance and extensive features that you may expect from a NAS. Based on the new OS software it earns our Storage Sweetness award.”


Running on the newly-designed, enhanced ThecusOS™ 7.0

The N5810 runs on the newly designed ThecusOS 7.0 offering an easy to use, intuitive user interface. Introducing several new features including Photo Station, Thecus App Center, User Profile, ThecusOS 7.0 delivers significant improvements in design, performance, and user experience. (OS7.0 phase-in on new production from 2016/03/15.)

Uninterrupted Accessibility with Thecus System Failover
The Thecus System Failover feature is a fault tolerance process that creates mirrored data volumes. With at least two Thecus NAS available, data is copied by schedule and all changes are mirrored between the two NAS. While the second NAS is not visible, it communicates with the primary NAS. In the event of a power or network failure, a scheduled maintenance, or other unforeseen circumstances, System Failover automatically redirects operations to the secondary Thecus NAS, which then acts as the primary NAS.
