How alternatives compare to Asustor
LincPlus LincStation E1 4-Bay NAS
The LincPlus LincStation E1 keeps the same 4-bay form factor and 4GB RAM but drops the dual 5GbE ports for a single 5GbE and a 2.5GbE port. It adds HDMI output, which the Asustor AS6704T v2 lacks, making it better for direct media playback. You lose the dual network redundancy but gain video connectivity. It is a lighter option at 2 pounds. Choose this if you want hybrid SATA and NVMe storage without needing two high-speed network connections for your setup.
Asustor Lockerstor 4-Bay Quad-Core NAS
The Asustor AS6604T shares the 4-bay design and quad-core processor but uses dual 2.5GbE ports instead of the dual 5GbE found in the AS6704T v2. It includes M.2 slots for NVMe flexibility but does not come with pre-installed SSDs. This model is significantly smaller and lighter, weighing only 6.53 pounds. It is a practical base for custom builds. Pick this if you want solid networking and expansion options without paying for included drives or needing the higher bandwidth of 5GbE ports.
Synology 4-Bay 16TB NAS
The Synology DS925+ bundle offers 16TB of storage in a 4-bay chassis with dual 2.5GbE ports. It features an AMD Ryzen processor and 4GB RAM, similar to the Asustor in core count but differing in network speed. It is heavier at 13.2 pounds. This unit targets small business virtualization and surveillance tasks. Choose this if you prioritize ECC memory reliability and a specific brand ecosystem over the dual 5GbE ports and included NVMe drives of the AS6704T v2.
Asustor Lockerstor 8-Bay 10GbE NAS
The Asustor Lockerstor 8 Gen3 expands to 8 drive bays and includes 16GB of RAM, doubling the memory of the 4-bay model. It adds 10GbE connectivity alongside 5GbE ports, offering much higher network throughput. It is designed for heavy-duty storage needs rather than compact setups. Select this if you need eight drive slots and high-end networking speeds. It sacrifices the compact footprint of the 4-bay unit for significantly greater capacity and bandwidth capabilities for professional environments.
Asustor Lockerstor 4-Bay 10GbE NAS
The Asustor AS6804T retains the 4-bay form factor but upgrades to 16GB RAM and an AMD Ryzen processor. It adds 10GbE connectivity to the existing 5GbE port, providing serious power for caching and high-speed networking. It is heavier and less plug-and-play than the AS6704T v2. Choose this if you prioritize maximum speed, caching performance, and high-end networking over simplicity. It fits users who need more RAM and faster network options than the standard quad-core model provides.
Asustor Lockerstor 10-Bay NAS with 2x 1TB SSD
The Asustor AS6810T scales up to 10 drive bays with 16GB RAM and dual 10GbE ports. It includes two 1TB SSDs and weighs 20.6 pounds. This unit is built for high-density storage and professional environments requiring ECC reliability. It sacrifices compactness for massive capacity and bandwidth.
