You may want another device if you need 10GbE connectivity, an all-SSD configuration, or a higher bay count. The selected alternatives were chosen because their specifications overlap with the original, ensuring you find a suitable replacement based on your specific technical requirements.
Our top pick: QNAP 4-Bay Rackmount NAS with 2.5GbE.
Comparing NAS Alternatives
Asustor Lockerstor 4-Bay Quad-Core NAS
The Asustor Lockerstor AS6604T offers 2.5GbE connectivity like the QNAP TS-464U but in a desktop form factor rather than a rackmount chassis. It includes M.2 NVMe slots for cache or storage, a feature the QNAP requires a separate PCIe card for. However, it provides only 4GB of RAM compared to the QNAP’s 8GB, which may limit heavy multitasking or virtualization workloads. This model suits users who want integrated NVMe support and a compact footprint without needing rackmount installation. You trade raw memory capacity for built-in SSD expansion and a different brand ecosystem.
QNAP 4-Bay 10GbE SFP+ NAS
The QNAP TS-431X3 distinguishes itself by including a dedicated 10GbE SFP+ port alongside its 2.5GbE connections, offering higher bandwidth potential for specific network setups. Like the TS-464U, it is a 4-bay unit, but it lacks the rackmount form factor. It also does not list a higher RAM capacity in its attributes, suggesting it may rely on the base configuration for typical use. This alternative is best if you prioritize a direct 10GbE uplink over the dual 2.5GbE ports and rackmount flexibility of the TS-464U. You gain network speed options but lose the physical mounting style.
Asustor AS3304T 4-Bay NAS
The Asustor AS3304T is a budget-friendly 4-bay NAS with 2.5GbE ports, matching the network speed of the QNAP TS-464U in a compact desktop design. It provides only 2GB of RAM, which is half the memory of the QNAP model, making it less suitable for demanding tasks or multiple concurrent users. This unit is ideal for home media storage and basic backup duties where high performance is not critical. You save on complexity and form factor requirements but accept lower memory capacity and a different brand interface. It fits users who need simple, reliable storage without rackmount needs.
Asustor Lockerstor 12-Bay Rackmount NAS
The Asustor AS6512RD is a 12-bay rackmount NAS, offering triple the drive capacity of the 4-bay QNAP TS-464U while maintaining similar 2.5GbE connectivity. It features 8GB of RAM, matching the QNAP’s memory capacity, and includes a quad-core processor for handling larger data sets. This model is designed for high-density storage needs in a rack environment. You gain significant expansion potential and bay count but accept a much larger physical footprint and higher weight. It is the choice for users who need substantial bulk storage rather than the compact 4-bay solution of the TS-464U.
QNAP 8-Bay Short-Depth Rackmount NAS
The QNAP TS-855eU provides an 8-bay capacity in a short-depth rackmount chassis, doubling the drive slots of the TS-464U. It also features 8GB of RAM and an 8-core processor, offering more processing power than the QNAP’s quad-core CPU. While it shares the 2.5GbE network connectivity, it focuses on density and core performance rather than the specific expansion card slots of the TS-464U. This alternative suits users needing high-density storage in a rack with strong processing capabilities. You trade the specific PCIe expansion flexibility of the TS-464U for greater bay count and core processing power.
Aiffro K100 4-Bay All-SSD NAS
The Aiffro K100 is a compact 4-bay NAS designed for all-SSD storage using M.2 NVMe drives, offering significantly faster performance than the HDD-focused QNAP TS-464U. It features an Intel N100 processor and 2.5GbE connectivity, matching the network speed but in a much smaller, desktop-sized package. This model is ideal for users prioritizing speed and efficiency for video editing or small team workflows over massive bulk storage. You gain rapid NVMe performance and a tiny footprint but lose the ability to use traditional large-capacity hard drives. It fits professionals needing speed rather than the TS-464U’s rackmount versatility.
