AS6604T vs AS6804T Comparison
Processor Performance
The Asustor Lockerstor 4-Bay 10GbE NAS (AS6804T) uses an AMD Ryzen Quad-Core processor running at 2.3 GHz. This provides a higher clock speed than the Asustor Lockerstor 4-Bay Quad-Core NAS (AS6604T), which features a standard Quad-Core 2.0GHz CPU. For tasks that rely heavily on single-threaded performance or quick file indexing, the 2.3 GHz speed offers a tangible boost. If your workflow involves heavy transcoding or running multiple virtual machines, the faster clock rate on the AS6804T will help maintain responsiveness under load compared to the base model.
Memory Capacity
Memory plays a critical role in NAS stability and app performance. The AS6804T comes equipped with 16GB of ECC DDR5 RAM. In contrast, the AS6604T provides 4GB of standard DDR4 RAM. The fourfold increase in capacity on the newer model allows for more simultaneous services and better caching efficiency. Additionally, the ECC (Error Correcting Code) feature in the AS6804T helps detect and fix internal data corruption, which is vital for data integrity. The DDR5 standard also offers higher bandwidth than the DDR4 found in the AS6604T, further enhancing overall system throughput.
Network Connectivity
Network speed determines how fast you can transfer files across your local area network. The AS6804T includes dual 5GbE ports and dual 10GbE ports, offering significant bandwidth for high-speed transfers or link aggregation. The AS6604T is limited to two 2.5GbE ports. While 2.5GbE is sufficient for many home users, the AS6804T’s 10GbE capability supports faster storage arrays and professional workflows. If you frequently move large media files or need to serve data to multiple high-speed clients, the AS6804T provides superior network flexibility and speed.
NVMe Slot Count
Both units support NVMe SSDs for caching or storage, but the expansion options differ. The AS6804T features four M.2 NVMe slots, allowing you to install up to four drives. The AS6604T offers two M.2 NVMe slots. If you plan to build a dedicated NVMe storage pool or use extensive caching for multiple datasets, the AS6804T provides double the expansion capability. The AS6604T is adequate for basic caching or a small SSD array, but the AS6804T offers more room for future storage growth within the chassis.
Physical Dimensions
Size matters when fitting a NAS into a rack or home office space. The AS6604T measures 6.69 inches in width, 7.3 inches in height, and 9.06 inches in length, weighing 6.53 pounds. The AS6804T is larger, measuring 12 inches in width, 10 inches in height, and 13 inches in length. The AS6604T has a more compact footprint, making it easier to place in tighter spaces. The AS6804T requires more desk or rack space due to its larger chassis and internal components. Choose the AS6604T if space is limited.
Which NAS model fits your needs
Users needing fast local network transfers
The AS6804T includes dual 10GbE ports alongside dual 5GbE connections. This setup allows you to achieve significantly higher data transfer speeds when moving large files between compatible devices. If your workflow involves frequent large file exchanges, these enhanced network interfaces provide the necessary bandwidth for efficient operations.
Users prioritizing maximum expandability and speed
This model features four M.2 NVMe slots and 16GB of ECC DDR5 RAM. The AMD Ryzen processor runs at 2.3 GHz, offering more headroom for demanding tasks. If you plan to use multiple SSDs for caching or run virtual machines, the superior memory and processor specifications support heavier workloads better than the alternative.
Users seeking a standard reliable setup
The AS6604T provides two 2.5GbE ports and 4GB of DDR4 RAM. It includes a Quad-Core 2.0GHz CPU and two M.2 NVMe slots. This configuration is sufficient for general home storage, media streaming, and basic file syncing. If you do not require 10GbE speeds or extensive RAM, this unit meets standard requirements.
