Thecus have created a new NAS that is something just a little bit special, if not a lot of special. It looks pretty normal on the surface, but it comes packed full of great features, plenty of storage abilities, and with connectivity options as they’re rarely seen.

The new Thecus Zero-Crash N5810 Pro isn’t your everyday NAS, it is one that comes with superior performance, unmatched security, and with built-in mini-UPS. The N5810 Pro is a 5-bay unit and this is an NAS form-factor that is increasing in popularity due to the option for an extra hot-spare, or just the extra capacity.


Let us dive right into the hardware specification, because they are worth highlighting. At the core of the unit we find an Intel Celeron J1900 quad-core SoC processor with 2GHz and the N5810 Pro comes equipped with 4GB DDR3 RAM right out the box. You don’t need to worry about having to upgrade your NAS right away with that kind of RAM, it is easily enough to run all the apps and service you want at the same time.

Where other NAS devices come with two and sometimes four LAN ports, Thecus added one extra and equipped this unit with a total of five Gigabit Ethernet ports. There is full support for all types of Link Aggregation and Fail-over, leaving the setup completely up to you. Maximum performance, redundancy, or you could even use it as an access point if you wanted to.

It has three USB 3.0 ports where one of them is located on the front for quick and easy backups. The last two are on the rear side with the rest of the connections such as two USB 2.0 ports, one HDMI port, and a Line-Out 3.5mm audio jack.


Thecus equipped the N5810 Pro with an internal 130W power supply. I really like the use of internal power supplies over the external power bricks, although the bricks are easier to replace if they should fail. Thecus also thought about that and made the PSU removable from the rear of the unit. It isn’t as easy as getting a new universal AC/DC adapter, but it’s close.

Another really awesome feature in this high-end NAS is the built-in mini-UPS with a removable battery. Again you save yourself having to get another piece of hardware and find room to place it near the NAS. You also save yourself the connecting and setting it up as everything is built-in. If the NAS should lose power, it will safely shut down without loss or corruption of your data. You can define the settings whether it should stay off or resume where it left off once the power is back.


The N5810 Pro NAS is placed on four large rubber feet that prevent any vibration from the mechanical hard drives to move onto whatever piece of furniture the NAS is placed on. They lift the unit far enough off the ground that it also has some extra air vents on the bottom that help to draw in more fresh and cold air for the system. The stickers with serial and product numbers are hidden away on the bottom if you should need those.

Security is an ever-growing issue and Thecus has this side of things handled with both their choice hardware, software and the physical build. Thecus has partnered with McAfee and bundled their Antivirus with the unit to keep the NAS save from itself. Those who prefer the private connections don’t need to worry either as the NAS fully supports VPN connections with the built-in server module.


Keeping the files safe means more than just to protect them from viruses and malware, and Thecus also has all the other sides of the story covered. The N5810 Pro supports scheduled Rsync backups and also comes bundled with Acronis True Image software for advanced one-click protection. Snapshot backup is equally supported with BTRFS support for subvolumes and easy rollback or restoration.

Those who wish to store their backup in the cloud are covered with support for DropBox, Amazon S3, and ElephantDrive. If that still isn’t enough, Thecus also supports data burn directly to CD, DVD, and Blu-ray disks with Data Burn. You can also choose to just ‘burn’ ISO files as another way of backing up your files. You can even clone entire disks with the NAS.


The five drive caddies can all be locked individually and Thecus included a total of four keys with this unit. Enough for even the most clumsy people that forget or lose them. The caddie’s base is built from steel and covered with a plastic encasing that holds the locking system and two LEDs. Thecus places padding inside the caddies to prevent damage to your drives and possible short-outs from the PCB touching the caddy. They support both 2.5-inch and 3.5-inch drives, so you’re covered no matter what drive you want to use, whether it’s small or big hard disks or even solid state drivers.


Thecus also built in a LCM display with four buttons on the front: enter, escape, up, and down. This not only allows you to view the current configuration, but also change settings. Not to worry, you’ll have to enter a password via the buttons in order to access that part.


Mobile connectivity is also supported with the T-OnTheGo and T-Dashboard apps. When I read those names I always think of Telecom first, but the T stands for Thecus in this case. You can connect from your iOS or Android device for up and downloading files, streaming media, or just to keep an eye on the device itself.


You can even turn the N5810 Pro into a direct multimedia hub for your living toom with the built-in HDMI. Connect it directly to your TV for device management, web browsing with Flash support, and also the most important function, HD video playback. No need to watch your movies on the PC monitor or have an extra HTPC running, just use your NAS. It also features a line-out connection to get the sound out to other devices if your monitor doesn’t have built-in speakers.
