How each alternative compares
TERRAMASTER 4-Bay Intel N95 NAS
The TERRAMASTER F4-425 Plus shares the Intel N95 quad-core processor and 8GB RAM of the original but swaps the all-SSD design for traditional drive bays. It retains the 5Gbps Ethernet port, ensuring fast networking for small offices needing SSD caching. However, it is significantly larger and heavier, measuring 8.62 inches long versus 2.36 inches. You gain flexible storage expansion options but lose the ultra-compact form factor. This model suits users who need 5GbE speeds and expandable capacity rather than a palm-sized, tool-free NVMe-only setup.
TERRAMASTER 6-Bay 8GB DDR5 NAS
The TERRAMASTER F6-424 increases drive capacity to six bays while keeping the Intel N95 processor and 8GB DDR5 RAM found in the original. It offers more storage slots for data-heavy workflows but sacrifices the compact, portable design of the F4 SSD. The unit is much larger, weighing 4.6 pounds and measuring 8.74 inches in length. You get extra drive space and modern memory speeds but give up the ultra-quiet, desktop-friendly footprint. This alternative is best for small businesses needing robust backup tools and higher density than four bays can provide.
Asustor Lockerstor 8-Bay Dual 10GbE NAS
The Asustor AS6508T offers eight bays and dual 10GbE ports, far exceeding the original’s four bays and single 5Gbps connection. It uses a quad-core processor with 8GB RAM, matching the original’s memory tier but in a much larger chassis. Weighing 13.7 pounds and measuring 11.5 inches wide, it is designed for high-capacity storage and heavy data workloads. You gain significant network speed and double the drive slots but lose the compact, quiet, and portable nature of the F4 SSD. This unit fits users who need enterprise-grade speed and density over space efficiency.
Asustor Lockerstor 4-Bay Quad-Core NAS
The Asustor AS6604T provides four bays and M.2 NVMe slots, similar to the original’s focus on SSD integration. However, it includes only 4GB of RAM and features dual 2.5GbE ports instead of a single 5Gbps port. The processor is a quad-core unit, but the total memory is half that of the original’s 8GB DDR5. It measures 9.06 inches long, making it longer than the compact F4 SSD. You get flexible networking and SSD support but sacrifice raw processing power and the fastest available Ethernet speed. This model suits users prioritizing dual 2.5GbE connectivity over maximum RAM and bandwidth.
Asustor AS3304T 4-Bay NAS
The Asustor AS3304T offers four bays with only 2GB of RAM and dual 2.5GbE ports, falling short of the original’s 8GB DDR5 RAM and 5Gbps Ethernet. It is a quad-core unit designed for basic file backup and home media storage. Measuring 9.06 inches long, it is larger and less portable than the palm-sized F4 SSD. You get an affordable entry point for home servers but lose the high-speed networking and substantial memory required for professional performance. This alternative is best for users who prioritize cost and basic media features over speed and capacity.
Asustor Lockerstor 12-Bay Rackmount NAS
The Asustor AS6512RD is a 12-bay rackmount NAS with 8GB RAM and dual 2.5GbE ports, offering significantly more drive slots than the original’s four bays. It uses a quad-core processor but is designed for high-density storage and virtualization in fixed rack setups. Weighing 25.8 pounds and measuring 17.3 inches wide, it is far from the original’s portable, quiet design. You gain enterprise features and massive storage density but sacrifice the compact, desktop-friendly form factor and 5Gbps networking speed. This unit suits data-heavy environments where space efficiency is not a priority.
