The AS6404T NAS is flexible and easy to configure in terms of the HDD’s capabilities; not only that, but we were also able to reach the transfer speed through a full single duplex Gigabit Ethernet connection. Generally, the Ethernet will occasionally bring in a couple of performance or lagging concerns through a network connection. We really liked the outcome and the NAS device is generally fast for all activities.

The AS6404T didn’t run into any issues on performance, and it also has a lot of spare performance because of the smart memory management. We felt that the ADM and GUI OS were generally fast and responsive, plus we also appreciated the updates made for the new ADM 3.0; moreover, the utilization of the processor also makes your apps adequately fast.

In regards to file transfer performance the AS6404T did a fantastic job. Transferring a file to the NAS saw speeds of around 98.3MBs while transferring a file from the NAS returned speeds of 92.5MBs. Playback of a full HD video file streamed at 85.1MBs.

How to Use

The method of arranging the ASUSTOR AS6404T 4-BAY NAS for the first time is generally easy and there isn’t really any need for high technical knowledge; if you’ve already set up something similar in the past, this procedure will come out as very standard. To start setting up the NAS device, you will need to point the browser to your NAS’ LAN IP address; after this, you will need to go through a wizard that’s quite simple then the operating system will start updating simultaneously with any other setting that comes to mind. However, if you haven’t really utilized a network-attached storage system, it wouldn’t come off as a problem since going through the whole setup process is a breeze.

ASUSTOR also made sure that all your settings and data can readily and seamlessly be migrated to the next system: all you need to do on this part would be to plug the disks in a similar manner as your previous NAS then everything will be ready and done. After setting up the NAS device, you will reach the login page and here, you will need to enter your password and username to get redirected to the main page; you can also choose to stay signed in so you won’t really have to bother signing in each time you access the page. The site’s interface is based on ASUSTOR’s built-in Linux-based OS which is referred to as the ADM or the ASUSTOR Data Master. This is said to be one of the most modern operating systems for NAS devices to date.

As for the web interface’s visual appearance, ASUSTOR’s ADM does exhibit a contemporary and sleek appearance that is also simple – something that a lot of users prefer. Utilizing an advanced scripting method for the whole design allows this to have an appearance that is sleek, clean, and practical; plus, you can also easily drag the icons around, add your own items, as well as remove shortcuts just like your real desktop.

The ADM OS is considered as a continuously evolving and developing GUI that is easy to navigate, install, and is also noted for being feature-rich when it comes to adding on applications. After logging in for the first time, a welcome guide to the ADM will pop up on the page; the ADM 3.0 version features a fresher and cleaner appearance for the operating system. Though one thing that you should remember is that once you modify the file structure, you won’t get to return to the previous version after upgrading.

The main page for the ADM display the primary sections of the operating system and at the top portion of the main menu window, you will see three different icons namely the “Search”, “Tools”, and “Admin”. For the “Admin” drop down, there are five choices namely personal, restart, sleep, sign out, and power off. If you’re wondering what the personal section is, this is where you can set up your e-mail address, account password, ADM language, and your description. The search icon takes you to the Searchlight which is the company’s own tool for searching; this is primarily designed for making precise and fast searches for data stored on the AS6404T. To the left of the search icon, you will find the tools icon; it drops down a couple of widgets that displays numerous AS6404T NAS functions for easier and seamless monitoring.  With the ADM 3.0, you can individually and easily tailor all your needs such as the ability to monitor the system’s status in real time without really having to login or open the application.

Just like with every other NAS device available, the disk management, volume creation, and RAID of the ASUSTOR AS6404T 4-BAY NAS are considered as the heart of the device.

As for the File Explorer, you can easily play music and browse photos directly from the device; plus, it also supports video playback files simultaneously during searches.

The App Support has continuously been the ADM’s strongest and most notable points. App Central is considered as the control center for managing apps since it features installed applications, updates, and all of the available apps. After checking the App Central, we’ve taken note of more than 245 apps available and counting. The newest feature for the ADM 3.0 is the App Central’s upgrade prompts: if there are any items that require upgrades, the App Central can now determine which these items are instead of just waiting for a complete upgrade of the ADM.  As for its Activity Monitor, this has also been improved with the new interface and it also supports real-time control of the NAS resources and system.

My Archive is a smart backup solution that allows you to utilize hard drives as removable ones; this is to allow the process of exchanging between numerous groups of data whenever necessary. This has just been upgraded recently and now, it supports NTFS, HFS+, as well as EX4 file systems. Since data security is essential especially in offices, My Archive drives support the AES 256bit encryption. The AS6404T NAS device offers up to three bays reserved for My Archive disks.

The ASUSTOR AS6404T is an upgrade to the company’s previous AS-6204-T and now features the Apollo Lake Celeron quad core J-3455 in replacement of the Celeron N-3150 which is something that we really appreciate from ASUSTOR. The latest version of the company’s ADM operating system enhances the best NAS operating system that is around. Just remember that once you update to the newest version of the operating system, you won’t be able to return to the previous version of the NAS device.

Another thing that we liked is that the interface has been revamped and now features a grouping function to allow you to group various applications together. Additionally, the ability to resize the application windows is another new feature that we liked since this makes it easier to read files with lengthy names. Desktop widgets are also present which can be really advantageous when it comes to monitoring the resource and health status of the AS6404T 4-BAY NAS; plus, it can also be user-defined so monitoring will be done dynamically and will be much easier since you won’t have to open any other apps.

A very powerful, efficient, and durable NAS that is easy to setup, the ASUSTOR AS6404T is well-suited for both office and home use; and with how excellent it performs, we definitely recommend this NAS device.
