Securely expand your network storage capacity with the QNAP TS-251D-2G 2-Bay NAS Enclosure, which supports up to two hot-swappable 3.5" or 2.5" SATA III drives that can be set up in RAID 0, 1, JBOD, or Single configuration. Powered by an Intel Celeron dual-core processor with 2GB of DDR4 memory, this 2-bay NAS enclosure is designed to efficiently back up your data, share files, and stream 4K media to connected users with a maximum read and write speed of 982 MB/s and 892 MB/s, respectively. You can upgrade the system's RAM to up to 8GB by installing a SO-DIMM module into the available memory slot. The available PCIe 2.0 x4 slot allows you to further enhance performance with devices such as a 10Gb Ethernet adapter, a USB 3.2 Gen 2 card, a wireless networking adapter, or a QNAP QM2 card for M.2 solid-state cache drives.
The TS-251D-2G connects to your network via Gigabit Ethernet. Three USB 2.0 ports are available for compatible peripherals alongside two USB 3.1 Gen 1 Type-A ports, which allow you to transfer data at up to 5 Gb/s with compatible devices. The HDMI 2.0 port allows you to connect displays directly to use a multimedia server. Additionally, your data is protected by AES-NI 256-bit hardware-accelerated encryption. The QNAP TS-251D-2G operates using the QTS 4.4.1 Linux-based operating system, which is accessible via web browser using Windows, Mac, and Linux computer systems.
