How each alternative compares
Synology 8-Bay Short-Depth Rackmount NAS
The Synology RS1221+ shifts from desktop to rackmount form factor, measuring 23 inches long. It offers eight bays instead of nine, saving one drive slot for a more compact 16.5-inch width. You get 4GB of RAM, a spec the TerraMaster listing does not provide. This unit suits professionals needing high uptime in a server rack. You trade the TerraMaster’s 10-core processor for Synology’s optimized NAS software ecosystem. If your workspace requires standardized rack mounting, this is the practical choice over the desktop TerraMaster.
Synology 12-Bay Quad-Core NAS
The Synology DS2422+ expands capacity significantly with twelve drive bays, surpassing the TerraMaster’s nine. It uses a quad-core processor, which is less powerful than the TerraMaster’s 10-core chip, but offers greater storage density. You also receive 4GB of RAM, allowing for better multitasking with virtual machines or containers. At 20.9 pounds, it is heavier than the TerraMaster. This model fits users who prioritize maximum storage expansion and future RAM upgrades over raw processing speed. It is ideal for large media libraries where capacity matters more than CPU intensity.
BUFFALO TeraStation 5420RN 16TB Rackmount NAS
The BUFFALO TS5420RN comes pre-loaded with 16TB of storage across four bays, eliminating the need to buy drives separately. It features a 10GbE port, offering faster network speeds than the typical 2.5GbE or 1GbE found in many competitors. However, it only has four bays, significantly less than the TerraMaster’s nine. The rackmount design changes how you place the device. This NAS suits teams needing immediate, secure storage with high network throughput. You sacrifice expandability for out-of-the-box readiness and superior network bandwidth for file transfers.
QNAP 16-Bay Hybrid NAS with Atom 8-Core
The QNAP TS-1655 provides sixteen drive bays, nearly doubling the capacity of the TerraMaster T9-500 Pro. It uses an 8-core Atom processor, which differs from the TerraMaster’s 10-core architecture. The unit includes 5GbE and 2.5GbE connectivity options, offering flexible networking speeds. It is larger and heavier, weighing more due to its extensive drive capacity. This NAS is best for users who prioritize massive storage expansion and memory upgrade paths over compact size. If you need to house many drives and want versatile network options, this QNAP model is the superior choice.
Glyph Blackbox PRO RAID 24TB Thunderbolt Drive
The Glyph Blackbox PRO is a desktop RAID drive using Thunderbolt connectivity, not a traditional network-attached storage device. It offers 24TB of capacity in a compact 5.5-inch wide chassis, much smaller than the TerraMaster. It lacks network ports, relying on direct connection to a Mac or Windows system. This unit suits video editors needing fast, local access to large media files. You give up multi-user network sharing and RAID configurations accessible over the network. If your workflow requires high-bandwidth direct storage for creative applications, this specialized drive is the better tool.
Synology 2-Bay 24TB NAS with Hard Drives
The Synology DS223j is a 2-bay NAS, offering far fewer drive slots than the TerraMaster’s nine. It includes 24TB of pre-installed storage, but limits you to two drives. It features a quad-core processor and 1GbE networking, which is slower than many modern NAS options. The unit is compact and lightweight at 6.85 pounds. It is designed for small home offices or basic home use. You trade significant capacity and processing power for simplicity and ease of use. If you need basic file sharing without complex management, this entry-level Synology model is a practical, simpler alternative.
