How these models differ from the TerraMaster
QNAP TS-264 2-Bay Desktop NAS
The QNAP TS-264 doubles your RAM to 8GB, which helps when running multiple virtual machines or containers. It shares the same Intel Celeron quad-core processor and dual 2.5GbE ports as the TerraMaster. You also get M.2 NVMe support for caching. This model is a desktop form factor, which may take more space on your desk. If you need more memory for heavy multitasking but want similar network speeds, this is a strong upgrade. The TerraMaster sticks with 4GB, which is sufficient for basic file serving but limits complex app usage.
Synology DiskStation 8TB 2-Bay NAS
This Synology unit comes pre-loaded with 8TB of storage, removing the need to buy drives separately. It uses a quad-core Intel Celeron processor and offers both 5GbE and 1GbE ports. However, it has less RAM than the QNAP alternative. The Synology ecosystem is known for its user-friendly interface and Btrfs file system support. You trade raw expandability for a ready-to-use solution with significant pre-installed capacity. If you want a plug-and-play experience with substantial built-in space, this fits your needs better than the empty TerraMaster chassis.
Asustor Lockerstor 4-Bay Quad-Core NAS
The Asustor Lockerstor provides four drive bays instead of two, doubling your potential storage capacity. It retains the 4GB RAM and dual 2.5GbE ports found in the TerraMaster. You also get M.2 NVMe slots for caching. This model is designed for users who need more space for large media libraries or extensive backups. The additional bays allow for more flexible RAID configurations. If your primary concern is storage volume rather than a compact footprint, this four-bay option offers significant expansion potential while keeping the same networking and processing speed.
Synology 2-Bay AMD Ryzen NAS
The Synology DS725+ features an AMD Ryzen processor, which generally offers stronger multi-threaded performance than the Intel Celeron in the TerraMaster. It includes 4GB of RAM and dual 2.5GbE ports. You also get M.2 NVMe support for caching. This model is ideal for users who need more processing power for transcoding or running demanding applications. The AMD Ryzen chip provides a performance edge in compute-heavy tasks. If you prioritize raw processing speed over the specific Intel architecture, this alternative delivers better computational throughput for small office environments.
LincPlus LincStation E1 4-Bay NAS
The LincPlus LincStation E1 offers four drive bays and includes an HDMI port for direct media playback. It has 4GB of RAM and dual 2.5GbE ports. The inclusion of HDMI allows you to connect directly to a TV or monitor for local streaming. This model is a hybrid storage solution designed for media enthusiasts. You gain extra drive bays and direct video output, which the TerraMaster lacks. If you want to use the NAS as a direct media center without additional hardware, this model provides unique connectivity options for local playback alongside standard network storage functions.
Asustor 4-Bay NAS with 1TB SSD
The Asustor AS6704T comes with a 1TB SSD pre-installed and offers four drive bays. It features dual 5GbE ports and M.2 NVMe slots. The 1TB SSD provides fast storage for caching or high-speed data access. This model is built for users who need high capacity and fast networking simultaneously. You get more bays and pre-installed fast storage compared to the TerraMaster. The dual 5GbE ports offer higher bandwidth potential than the TerraMaster's 2.5GbE ports. If you require maximum storage expansion and high-speed networking for large file transfers, this robust four-bay unit is a superior choice.
