How each alternative compares
LincPlus LincStation E1 4-Bay NAS
The LincPlus LincStation E1 4-Bay NAS shares the same quad-core processor, 4GB RAM, and dual 2.5GbE/5GbE ports as the Asustor AS6604T. Its main difference is the inclusion of an HDMI interface, which the Asustor lacks. This allows direct video output to a display, making it better for home media streaming without a separate TV. It weighs only 2 pounds, significantly lighter than the 6.53-pound Asustor. You should pick this if you prioritize local privacy and direct HDMI playback over enterprise features like included surveillance licenses.
Asustor Lockerstor 4-Bay NAS with 4TB SSD Storage
The Asustor AS6704T v2 also includes HDMI output, similar to the LincPlus, but adds dual 5GbE ports instead of the single 2.5GbE/5GbE mix found in the AS6604T. It comes with 4TB of pre-installed SSD storage, whereas the AS6604T is diskless. This model is larger, weighing 12.2 pounds compared to the AS6604T's 6.53 pounds.

It is designed for users needing extra drive slots and fast SSD caching. Pick this if you require higher capacity, more RAM, and 10GbE connectivity, and have the space for a heavier chassis.
QNAP 4-Bay 10GbE SFP+ NAS
The QNAP TS-431X3 is a 4-Bay NAS that matches the Asustor's form factor but adds dedicated 10GbE SFP+ ports alongside 2.5GbE and 5GbE connectivity. It weighs 5.1 pounds, lighter than the AS6604T's 6.53 pounds. Unlike the Asustor, it does not list RAM or processor specs in the provided data, but it focuses on flexible multi-gigabit networking. It is suitable for users who need 10GbE access without adding an expansion card. Choose this if you prioritize advanced network flexibility and a lighter chassis over the Asustor's included surveillance licenses and specific quad-core 2.0GHz processor.
Asustor AS3304T 4-Bay NAS
The Asustor AS3304T is a 4-Bay NAS with 2GB RAM, half the memory of the AS6604T's 4GB. It shares the quad-core processor and 2.5GbE/5GbE networking capabilities. It weighs 4.85 pounds, significantly lighter than the AS6604T. This model is designed for home users who need basic storage and media server features without high-end processing power. It lacks the NVMe slots found in the AS6604T. You should pick this if you prioritize capacity and basic performance over RAM and SSD caching speed. It is a simpler option for essential home storage needs.

Frequently asked questions
Can I replace the Asustor AS6604T with the LincPlus LincStation E1?
Yes, if you prioritize local media playback over enterprise networking. The LincPlus E1 matches the Asustor in having a quad-core processor, 4GB RAM, and 5GbE/2.5GbE ports. Its key difference is the added HDMI interface, which allows direct video output to a display. This makes it better for home media streaming and privacy-focused setups.
Does the Asustor AS6704T v2 offer better networking than the AS6604T?
It offers dual 5GbE ports instead of a mix of 5GbE and 2.5GbE. Both units feature quad-core processors and 4GB RAM. The AS6704T v2 also includes HDMI output for direct media playback. You get faster local transfer speeds with the dual 5GbE configuration, though the physical footprint is larger at 12 by 10 inches.
Is the Synology DS725+ a suitable 4-bay alternative?
No, it is a 2-bay model. It uses an AMD Ryzen processor and includes 4GB RAM. It supports 5GbE, 2.5GbE, and 1GbE connectivity. This NAS is designed for compact home office storage with NVMe flexibility. You would need to look at the Asustor or QNAP 4-bay options if you require four drive slots for your data.
Which alternative provides the fastest network connectivity?
The Asustor Lockerstor 6 Gen2 offers the fastest options with 10GbE, 5GbE, and 2.5GbE ports. It also includes 8GB of RAM and a quad-core processor. The QNAP TS-431X3 is another strong choice, featuring dedicated 10GbE SFP+ and 2.5GbE ports. These models suit users needing high-speed transfers for multi-client access without add-in cards.
Can I use the Asustor AS3304T for heavy multi-gigabit tasks?
