RAM, Network, and Storage Specs
RAM Capacity
The TerraMaster F4-424 Pro comes with 32GB of DDR5 memory running at 4800MHz. This high-capacity RAM is non-ECC and non-upgradable, providing a substantial buffer for heavy multitasking and large virtualization workloads. In contrast, the TerraMaster F4-425 Pro includes only 8GB of RAM. While sufficient for basic file serving and light container usage, the lower memory limit may constrain performance when running multiple Docker containers or demanding virtual machines simultaneously. For users prioritizing raw memory headroom, the F4-424 Pro offers a clear advantage with its significantly larger capacity.
Network Connectivity
Network bandwidth differs significantly between these two enclosures. The F4-425 Pro features dual 5GbE ports, which can be link-aggregated to provide up to 10GbE total bandwidth. This higher throughput is ideal for users moving large video files or running high-speed local backups. The F4-424 Pro is equipped with dual 2.5GbE ports, offering a maximum aggregated speed of 5GbE. While this is sufficient for most small office environments, it is half the potential speed of the F4-425 Pro. If your workflow involves frequent large data transfers, the faster ports on the F4-425 Pro are beneficial.
M.2 NVMe Slots
Storage expansion via M.2 NVMe SSDs is handled differently in each model. The F4-425 Pro includes three M.2 NVMe slots, allowing for more extensive caching configurations or dedicated SSD storage pools. This flexibility supports Hyper Cache acceleration for improved disk array performance. The F4-424 Pro provides only two M.2 NVMe slots. While this is adequate for basic SSD caching or a small secondary volume, it offers less flexibility for users who want to dedicate multiple SSDs to specific tasks or maximize cache size. The extra slot on the F4-425 Pro provides more options for storage architecture.
RAID Support
Both systems support standard RAID configurations, including RAID 0, 1, 5, 6, and 10, as well as JBOD and single drive modes. However, the F4-425 Pro includes exclusive TRAID technology. This feature allows for mixed-capacity drives within the same array, maximizing usable space and enabling online expansion without data migration. The F4-424 Pro data does not mention TRAID support, implying it relies on traditional RAID methods where drive capacities must match for optimal efficiency. For users who want to mix old and new drives or expand arrays easily, the F4-425 Pro offers superior flexibility.
Build Quality
Physical construction details highlight different design priorities. The F4-424 Pro weighs 4.2 pounds and measures 7.05 by 6.06 by 8.74 inches. It features a tool-free hard disk tray with a Push-Lock design and includes sound-absorbing panels to minimize operational noise. The F4-425 Pro is heavier at 6.39 pounds and measures 7.13 by 5.91 by 8.62 inches. While it also supports tool-free installation, the data does not specify noise-reduction features or the Push-Lock mechanism. The F4-424 Pro appears designed with a specific focus on quiet operation and secure drive locking, which may appeal to users in shared or residential spaces.
