Differences in Design

Asustor AS6404T specifies a greyish black outlook.

Four drive bays are present on its front side with an LCD screen and a peripheral bar containing various LED indicators (Power, System Status, Hard Disk, Network, and USB).

While four USB Ports, a System Fan, an HDMI Port, two 1GbE ports, an S/PDIF Port, a Reset Button, a K-lock, and the DC Inlet are located on its rear side.

The S/PDIF port gives it an edge over its competitor because it provides better audio quality.

Additionally, its USB interface is enhanced due to the presence of an extra Type C port.

Nonetheless, its Gigabit Ethernet ports are comparatively less efficient and its temperature endurance range is also smaller.

Asustor AS5304T is a lightweight NAS characterizing a blackish, sleek, and minimalistic look. It also has 4 bays but its drive bays are covered with a protective lid.

LED indicators are present on its front panel while the rear panel contains three USB Ports, an HDMI 2.0a Port, two 2.5 Gigabit RJ45 Ports, a Reset Button, a System Fan, a K-Lock, and the DC Input.

Due to the more efficient HDMI port, it offers more vibrant video streaming.

Similarly, its LAN efficiency is higher as its Ethernet ports are 2.5 GbE.

However, it lacks an S/PDIF port and also has fewer USB slots.

Also Compare Asustor AS5304T vs QNAP TS-230.

Differences in Speed

Both these gadgets have a quad-core processor but Asustor AS5304 has faster reading and writing speeds than its competitor because it operates with a high processing frequency.

Its data transmission rates are further improved because it has better Ethernet ports (2.5GbE).

On the other side, Asustor AS6404T specifies a lower frequency which is why its ability to analyze and sift through the database is lesser than the competitor.

Likewise, it requires a longer time to store new files.

Processing frequency1.5GHz (burst up to 2.5 GHz)1.5 GHz (burst up to 2.3GHz)
Reading speed564 Mb/s219 Mb/s
Writing speed551 Mb/s221 Mb/s

Differences in Cloud storage

Both these NAS enable users to create a private cloud database. Asustor cloud service can hold data for multiple user accounts and can execute various sharing and backup tasks simultaneously.

Users can utilize the NAS files through Cloud Backup Center applications.

Moreover, deleted versions are retained and can be restored through the Snapshot Center easily.

These systems also support sharing and synchronization with various public cloud accounts.

For this Asustor AS6404T takes the lead over the contestant as it supports more commercial cloud platforms.

In comparison, Asustor AS5304T has the same cloud efficiency, but it supports fewer commercial cloud services.

Differences in OS and Internet browsers

These Asustor devices work well with all leading operating systems including Windows (XP, Vista, 7, 8, 10, 11), macOS (10.6 and up), UNIX, Linux, and BSD.

Due to the cross-platform compatibility, users can stream multimedia content and utilize the stored files through any device operating with these OS.

Multimedia streaming services like Plex and Spotify are also supported.

For web-based purposes and synchronization, these gadgets support Firefox, Chrome, Safari, and Microsoft Edge.

Differences in Backup

When it comes to backup, both these NAS rank at the same level.

These gadgets provide more than twelve backup options including Rsync backup, Cloud backup, FTP backup, MyArchive, External disk backup, USB one-touch backup, and EZ Sync.

These tools support the Backup Plan for Windows and Time Machine for macOS.

Both of them provide local backup through various RAID levels.

Likewise, these devices provide tolerance for two disk faults and also support btrfs files and snapshot replication.


Sharing ability of both devices is the same, they allow an equal number of users to connect.

Similarly, these gadgets have an equivalent capacity for sharing folders and making groups so the team members can work and collaborate effectively on multiple tasks.

For the proficient management of disk space, these devices provide the facility to allocate specific quotas to users and groups.

Likewise, both these NAS supports LDAP, and their ability to make concurrent connections is also similar.

Differences in Durability and Warranty

Both devices are well-built using robust casing and efficient hardware components.

To back up their durable performance Asustor gives a replacement warranty for up to 3 years for both of these cloud devices.

However, Asustor AS5304T seems more durable in comparison as its drive bay openings have dual protection (drive handles and outer covering), ensuring complete safety from physical damages.

Plus, its temperature endurance is also higher which saves it from the damage of low temperatures.

On the other side, Asustor AS6404T has no protective lid on its drive bays.

Hence, it is more vulnerable to physical damage than its competitor.

Furthermore, it has less ability to withstand low temperatures and its functional components are badly affected when used in highly cold temperatures.

Differences in Noise

Asustor AS6404T is a quieter device and makes lesser noise (17.6 dB) than its competitor as it works with a lower operating frequency.  

In comparison, AS5304T processes the data quickly leading to better operations as well as up to 19.7 dB noise production.

Thus, it is a relatively louder cloud storage system.
