TerraMaster 6-Bay vs 4-Bay 1U Comparison
form factor
The TerraMaster F6-424 uses a standard desktop tower design, measuring 9.06 inches in length, 5.91 inches in width, and 6.69 inches in height. This footprint allows it to sit comfortably on a desk or shelf without requiring special mounting hardware. In contrast, the TerraMaster U4-500 is a 1U rackmount unit. It measures 14.2 inches in length and 17.3 inches in width, with a slim 1.77-inch height. This form factor is built for standard server racks, prioritizing space efficiency in data centers or dedicated IT closets over standalone desktop placement.
number of bays
Storage capacity starts with the physical drive slots. The TerraMaster F6-424 provides six drive bays, offering more immediate space for expanding your storage pool. This is ideal if you plan to install multiple large-capacity hard drives for media libraries or extensive backups. The TerraMaster U4-500 offers four drive bays. While it supports high-density configurations up to 96TB using 24TB drives, the total number of individual drive slots is lower. If your primary need is simply having more slots for smaller drives or future expansion without swapping larger ones, the six-bay model provides a clear advantage in raw slot count.
processor
Processing power differs significantly between these two units. The TerraMaster F6-424 utilizes a generic quad-core processor, which handles basic NAS tasks efficiently. The TerraMaster U4-500 features an Intel Core i3-1215U processor from the 12th generation. This chip has six cores and eight threads, with turbo speeds up to 4.4GHz. For heavy workloads like virtualization, 4K video editing, or running multiple Docker containers, the i3-1215U offers superior multi-threading performance and modern architecture compared to the standard quad-core option found in the F6-424.
network connectivity
Data transfer speeds depend heavily on your network infrastructure. The TerraMaster U4-500 includes dual 10GbE ports, providing an aggregate bandwidth of 20Gbps. It also supports SMB multichannel, which can combine the two ports for even faster transfers if your switch supports it. This is crucial for high-performance environments or large file transfers. The TerraMaster F6-424 data does not specify network port speeds or types. Without explicit 10GbE support listed, you should assume it relies on standard Gigabit Ethernet, making the U4-500 the superior choice for high-speed local network transfers.
cache technology
Caching improves read and write speeds for frequently accessed data. The TerraMaster U4-500 features dual M.2 NVMe slots with Hyper Cache technology. This allows you to install fast NVMe SSDs to accelerate performance for backups and data access, which is particularly useful for performance-driven small businesses. The TerraMaster F6-424 data does not mention any NVMe slots or dedicated cache acceleration features. If you require accelerated storage performance through SSD caching, the U4-500 provides the necessary hardware. Otherwise, both units rely on the speed of the installed HDDs or SATA SSDs.
Which TerraMaster NAS Fits Your Needs
Users needing maximum local storage capacity
The F6-424 offers six drive bays, providing more raw storage potential than the four-bay U4-500. Its desktop tower design fits easily on standard shelves or desks. If you prioritize physical drive count and simple placement over rack mounting, this six-bay unit is the practical choice for high-capacity local archives.
Businesses requiring rack-mounted server infrastructure
The U4-500 features a 1U rackmount form factor designed for standard server cabinets. It includes dual 10GbE ports for high-speed network connectivity and Intel UHD Graphics for hardware acceleration. If your workspace uses server racks and you need enterprise-grade connectivity and accelerated data processing, this model is the correct fit.
Professionals needing NVMe caching performance
The U4-500 includes dual M.2 NVMe slots with Hyper Cache technology to boost storage efficiency. It delivers 2090MB/s sequential writes and supports RAID 0, 1, 5, 6, 10, and TRAID configurations. If you require fast data access for video production or virtualization, the NVMe acceleration and advanced RAID options are essential.
