How the Alternatives Compare
Asustor Lockerstor 4-Bay Quad-Core NAS
The Asustor Lockerstor 4-Bay NAS gives you two extra drive bays compared to the Synology DS725+. This expansion allows for greater storage capacity without needing an external expansion unit. It retains the M.2 NVMe interface for caching, similar to the Synology model. However, it uses a generic quad-core processor rather than the specific AMD Ryzen R1600 found in the Synology. You also get dual 2.5GbE ports instead of the Synology’s mix of 2.5GbE and 1GbE. Choose this if you need more physical drive slots and do not require the specific Ryzen architecture or the single gigabit backup port.
QNAP TS-264 2-Bay Desktop NAS
The QNAP TS-264 offers double the RAM of the Synology DS725+, providing 8GB instead of 4GB. This extra memory supports more concurrent tasks and virtual machines. It uses an Intel Celeron quad-core processor, which differs from the Synology’s AMD Ryzen chip. Like the Synology, it includes M.2 NVMe slots for SSD caching. It features dual 2.5GbE ports, removing the 1GbE port found on the Synology. This model suits users who prioritize higher RAM capacity and SSD flexibility over raw processor performance or having a gigabit Ethernet fallback.
Synology DS225+ 2-Bay NAS
The Synology DS225+ shares the same 2-Bay form factor and brand ecosystem as the DS725+. It uses an Intel Celeron J4125 processor, which is less powerful than the Ryzen R1600 in the DS725+. It also has expandable memory, though the base configuration may differ. The DS225+ includes dual Ethernet ports, typically 5GbE and 1GbE, offering network redundancy similar to the DS725+. However, it lacks the M.2 NVMe slots present in the DS725+. Pick this model if you value data protection features like Btrfs snapshots and do not need NVMe caching or high-end Ryzen processing power.
Synology 4-Bay 16TB NAS
The Synology DS925+ moves you from a 2-Bay to a 4-Bay chassis, doubling your drive capacity options. It retains the AMD Ryzen processor, ensuring similar high-performance computing capabilities for demanding applications. It includes 4GB of RAM, matching the DS725+. The network configuration features dual 2.5GbE ports, differing from the DS725’s 2.5GbE and 1GbE mix. This unit is heavier and larger. Choose this alternative if you need more drive bays for storage expansion but want to keep the AMD Ryzen architecture and Synology ecosystem without adding an external expansion unit.
TerraMaster F2-423 2-Bay NAS
The TerraMaster F2-423 provides dual 2.5GbE ports, similar to the dual 2.5GbE setup in some Synology models, but lacks the 1GbE port found in the DS725+. It uses an Intel Celeron quad-core processor instead of the AMD Ryzen chip. It includes 4GB of RAM, matching the DS725+. The chassis is aluminum, which may offer different thermal properties compared to the DS725+. It supports SSD caching via M.2 slots. This model is a solid choice if you value a quiet aluminum build and fast 2.5GbE connectivity, and do not require the specific Ryzen performance or the gigabit Ethernet backup.
LincPlus LincStation E1 4-Bay NAS
The LincPlus LincStation E1 expands your options with a 4-Bay chassis, offering more drive slots than the 2-Bay DS725+. It includes M.2 NVMe slots for caching, similar to the Synology. A key difference is the inclusion of an HDMI port, which the DS725+ lacks, allowing for direct media playback. It uses a quad-core processor and 4GB of RAM. The network setup features dual 2.5GbE ports. Choose this model if you need a dedicated home media center with direct video output and more storage bays, while still wanting NVMe caching capabilities.
