FAQ
How many hard drives can the UNAS-2-W support?
The UNAS-2-W supports up to two 3.5" hard drives. The system comes with zero drives installed, allowing you to select and install drives that match your capacity, performance, and budget requirements. This two-bay configuration supports various RAID modes for data protection or performance optimization.
What type of processor does this NAS use?
This NAS system uses an ARM Cortex A55 quad-core processor running at 1.70 GHz. ARM processors are known for their power efficiency and are commonly used in NAS devices where low power consumption and adequate performance for storage tasks are priorities over maximum compute performance.
What networking speeds does the UNAS-2-W support?
The single RJ-45 network port supports 2.5 Gigabit Ethernet, Gigabit Ethernet, and Fast Ethernet standards. This means it can connect at speeds up to 2.5 Gbps with compatible network equipment, or automatically negotiate down to 1 Gbps or 100 Mbps for compatibility with older network infrastructure.
How much memory is included with this NAS system?
The UNAS-2-W comes with 4 GB of standard memory installed. This memory supports the NAS operating system, file system operations, and concurrent data transfers. For most basic NAS workloads including file sharing, media serving, and backup operations, 4 GB provides adequate performance.
What is the form factor of the UNAS-2-W?
This NAS system has a desktop form factor, meaning it's designed to sit on a flat surface rather than mount in a server rack. The compact dimensions of 5.31" H x 5.08" W x 8.81" D make it suitable for placement on desks, shelves, or in small network cabinets where space is limited.
What comes in the box with the UNAS-2-W?
The package includes the UNAS 2 NAS storage system itself and a power adapter. Hard drives are not included, allowing you to select drives that match your specific capacity and performance requirements. The power adapter provides the necessary 60 W maximum power for the system and installed drives.
