The QNAP TS-251D-2G-US is a 2-bay NAS enclosure built to handle network storage, file sharing, backups, and media streaming with ease. It supports two SATA drives, either 2.5" or 3.5", which you can set up in RAID 0, RAID 1, JBOD, or as single drives depending on your needs. Powered by an Intel Celeron dual-core processor and 2GB of DDR4 memory that you can expand up to 8GB, this NAS delivers reliable performance for everyday tasks and more demanding applications.
One of the standout features is the PCIe 2.0 x4 slot, which lets you add upgrades like a 10Gb Ethernet card for faster network speeds, USB 3.2 Gen 2 ports for quicker data transfers, or M.2 SSD caching to boost storage performance. The device also includes Gigabit Ethernet connectivity, multiple USB ports (two USB 3.2 Gen 1 and three USB 2.0), and an HDMI 2.0 output that supports 4K video playback, making it a versatile choice for both work and entertainment.
This NAS is ideal for small offices or home users who need a secure and flexible storage solution. It runs on QTS 4.4.1, a Linux-based operating system that offers a wide range of apps to help you manage your data, automate backups, and stream multimedia content smoothly. With AES-NI 256-bit hardware encryption, your data stays protected without sacrificing performance.
