QNAP TS-433-4G - NAS server, White

The QNAP TS-433-4G is a 4-bay NAS designed for home and small office use. It features a 2.0 GHz quad-core ARM Cortex-A55 processor to handle data tasks and multi-user access. The four internal drive bays support 3.5-inch and 2.5-inch SATA HDDs and SSDs. Network connectivity is provided by two Ethernet ports—supporting 2.5 GbE, 1 GbE, and 100 Mbps—for local data transfers. Data is organised using RAID levels 0, 1, 5, 6, 10, or JBOD for redundancy. The system runs on QTS 5.0.1, providing a web-based interface for file management.

A single 120 mm fan in the white tower chassis provides active cooling. External connectivity includes one USB 3.2 Gen 1 port and two USB 2.0 ports for drives or peripherals. Security features include 256-bit AES encryption and Access Control Lists for managing user folder permissions. The NAS is compatible with Windows 11, macOS, and various Linux distributions. Management tools, including system logging and Wake-on-LAN, assist with daily administration and power efficiency. Snapshot technology enables point-in-time recovery to protect against accidental deletion or corruption.
