Frequently asked questions
Is the BUFFALO TeraStation 5420RN suitable for home use?
This unit is designed for enterprise environments, not typical home offices. Its rackmount form factor requires a standard server rack for installation. The physical dimensions of 23 inches wide and 21.3 inches high are bulky for residential spaces. You should consider desktop NAS models if you lack rack infrastructure or need quieter operation in a living area.
What is the actual usable storage capacity?
The system ships with 32TB of raw storage using four 8TB drives. However, RAID 5 configuration reduces this to 24TB of usable space. This setup protects your data against one drive failure. You lose one drive worth of capacity for parity. Plan your file storage around the 24TB limit for optimal performance and redundancy.
Does this NAS support 10GbE networking?
Yes, the BUFFALO TeraStation 5420RN includes a 10GbE port for fast data transfers. This allows teams to move large files quickly within your local network. You must ensure your switch and cables also support 10GbE to utilize this speed. Standard 1GbE connections will bottleneck performance if you do not upgrade your network infrastructure.
How heavy is the fully loaded unit?
The complete unit weighs 27.2 pounds. This weight includes the chassis and the four pre-installed 8TB hard drives. You need a server rack rated to support this load safely. Ensure your rack mounting rails can handle the weight to prevent structural stress. Proper ventilation is also critical given the density of components inside the black chassis.
Can I expand the storage beyond 32TB?
The data provided specifies the unit ships with 32TB total capacity. It does not explicitly list expansion slots or external enclosures. You should check the official manual for additional bays or expansion options. For now, the four-bay design limits you to the installed drives. Plan your storage needs carefully around the initial 24TB usable RAID 5 space.
What is the model number for this specific configuration?
The specific model number for this 32TB configuration is TS5420RN3204. This identifier helps you verify you are purchasing the exact 4-bay rackmount unit. It distinguishes this model from other TeraStation variants with different capacities or form factors. Keep this number handy when checking compatibility with your existing rack equipment or software licenses.
