6 Best Alternatives to the TERRAMASTER T12-500 Pro NAS 12Bay (2026)

How these models compare

TERRAMASTER 8-Bay 2U Rackmount NAS

The TERRAMASTER U8-500 Plus keeps the 16GB RAM and Intel Core processor power found in the T12-500 Pro. It drops three drive bays to reduce size and cost. This 8-bay unit is a 2U rackmount design, which changes how you install it. It still supports NVMe caching for faster access. You gain a more compact footprint but lose the ability to store up to 288TB of data. This option suits users who need high network throughput and processing power but do not require the full 12-bay capacity of the original model.

Synology 12-Bay Quad-Core NAS

The Synology DS2422+ matches the 12-bay capacity of the T12-500 Pro but starts with only 4GB of RAM. It uses a quad-core processor instead of the 10-core Intel chip in the original. You get the same number of drive slots but must purchase additional RAM yourself to reach similar performance levels. This model prioritizes expandability and brand ecosystem over out-of-the-box speed. It is a better fit if you want to customize your memory configuration later. You sacrifice immediate high performance for the flexibility to scale resources as your data needs grow over time.

Synology 12-Bay Xeon Desktop Enclosure

The Synology DS3622xs+ also offers 12 drive bays and 16GB of RAM. It uses a Xeon processor, which differs from the Intel Core i7 in the T12-500 Pro. This unit is designed for high-performance virtualization and large-scale storage expansion. It provides robust IOPS capabilities for enterprise workloads. You get a different processor architecture and a focus on scalability rather than the specific backup features of the TERRAMASTER suite. This alternative is ideal for users who prioritize raw processing power and enterprise-grade virtualization support over the specific software tools included with the original model.

TERRAMASTER 8-Bay All-NVMe SSD NAS

The TERRAMASTER F8 SSD Plus is a compact 8-bay NAS that uses all NVMe SSDs. It features an 8-core Intel processor and 16GB of RAM. This model is significantly smaller and lighter than the T12-500 Pro. You trade large HDD capacity for extreme SSD speed and a tiny footprint. It is designed for virtualization and high-speed data access. This option suits users who need maximum IOPS and have limited space. You give up the ability to store massive amounts of data on traditional hard drives in exchange for a much faster, more portable storage solution.

Asustor Lockerstor 6-Bay AMD Ryzen NAS

The Asustor AS6806T offers 6 drive bays with 16GB of RAM and an AMD Ryzen quad-core processor. It includes both 5GbE and 10GbE network connectivity. This model is smaller than the 12-bay T12-500 Pro but still provides strong networking specs. You lose half the drive capacity but gain a different processor architecture. It is suitable for users who need 10GbE speeds and NVMe support without needing a 12-bay enclosure. This alternative is best for those who prioritize network versatility and modern processor performance over maximum drive count.

Asustor Lockerstor 4-Bay 10GbE NAS

The Asustor AS6804T provides 4 drive bays with 16GB of ECC RAM and an AMD Ryzen quad-core processor. It includes 5GbE and 10GbE ports. This unit is much smaller than the T12-500 Pro. You gain error-correcting code memory for data integrity but sacrifice eight drive bays. It is designed for users who need high reliability and network speed in a compact form factor. This option is ideal for those who prioritize memory stability and fast connectivity over large storage capacity. You get a focused, high-performance unit for specific tasks rather than a general-purpose large storage array.
