6 Best Alternatives to the TERRAMASTER 8-Bay 2U Rackmount NAS (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The TERRAMASTER U8-500 Plus NAS 8 bay alternatives list helps you find storage that matches your specific technical needs. This original model uses an Intel Core i7 processor with 16GB of DDR5 RAM and dual 10GbE ports for heavy business backup tasks. Its eight 3.5-inch drive bays support RAID configurations up to 192TB of capacity. You might look for different options if you need a smaller footprint or distinct connectivity features.
The alternatives on this page were chosen because their specs overlap with the original. For instance, the TERRAMASTER F8 SSD Plus offers a compact all-NVMe design, while the Synology RS1221+ provides a short-depth rackmount form factor. The Asustor Lockerstor 8-Bay includes ECC RAM for enhanced stability, and the UGREEN DXP8800 Ultra adds Thunderbolt 4 for creative workflows. Each option varies in processor core count, memory type, and network interface. You can compare these specifications to determine which hardware best supports your virtualization, video editing, or data protection requirements without exceeding your physical space or budget constraints.
Our top pick: TERRAMASTER 8-Bay 2U Rackmount NAS.
How each alternative compares
TERRAMASTER 8-Bay All-NVMe SSD NAS
The TERRAMASTER F8 SSD Plus replaces the original’s bulky 2U rackmount chassis with a compact desktop design. It uses an all-NVMe SSD configuration instead of supporting 3.5-inch SATA drives, which limits capacity to 64TB but ensures silent operation and lower power use. While it retains 16GB of RAM, the processor drops to an 8-core variant rather than the original’s 10-core i7. This model suits users who need fast, quiet storage for smaller datasets rather than heavy virtualization workloads in a server rack.
TERRAMASTER T12-500 Pro 12-Bay NAS
The TERRAMASTER T12-500 Pro increases drive capacity from eight to twelve bays while keeping the same 10-core processor and 16GB DDR5 RAM. It maintains dual 10GbE connectivity for high-speed networking, matching the original’s throughput capabilities. The primary difference is physical size, as the 12-bay enclosure requires more rack space than the 8-bay model. This option is ideal for teams that need the original’s performance but require additional storage volume for growing datasets without upgrading to a completely different system.
Synology 8-Bay Short-Depth Rackmount NAS
The Synology RS1221+ offers a shorter depth than the original TERRAMASTER, making it easier to fit in tight rack environments. However, it includes only 4GB of RAM, which is significantly less than the original’s 16GB DDR5. This lower memory configuration limits its ability to handle heavy virtualization or caching tasks. It lacks the dual 10GbE ports found in the original, relying on standard gigabit connectivity. This NAS is best for users who prioritize compact footprint and expandability over raw processing power and high-speed networking.
UGREEN DXP8800 Ultra 8-Bay NAS
The UGREEN DXP8800 Ultra distinguishes itself with Thunderbolt 4 connectivity, offering direct high-speed attachment for creative workstations. While it matches the original’s 8-bay capacity, it prioritizes memory expandability for virtualization over raw CPU core count. The original uses an Intel Core i7 with 10 cores, whereas the UGREEN model focuses on different performance metrics suited for creative asset management. This alternative is better for users needing immediate high-speed data transfer to Mac or Windows workstations rather than a traditional network-attached backup server.
Asustor Lockerstor 8-Bay 10GbE NAS
The Asustor Lockerstor 8-Bay uses an AMD Ryzen quad-core processor instead of the original’s Intel Core i7. It supports ECC RAM for enhanced data stability, a feature not specified for the original. Networking includes both 5GbE and 10GbE ports, providing flexibility. The original offers 16GB DDR5 and dual 10GbE ports with a 10-core CPU. This Asustor model is preferable for users who prioritize memory error correction and AMD-based architecture over the higher core count and DDR5 speed of the TERRAMASTER.
Asustor Lockerstor 6-Bay AMD Ryzen NAS
The Asustor AS6806T reduces the form factor to six bays, offering less total drive capacity than the original’s eight bays. It retains 16GB of DDR5 RAM and includes both 5GbE and 10GbE ports, matching the original’s high-speed networking potential. The processor is an AMD Ryzen quad-core, differing from the original’s Intel Core i7. This model suits users who need ECC memory and high-speed networking but can accept lower drive capacity for a more compact footprint than the 2U rackmount original.
