OVERVIEW
The QNAP TS-251D is an entry-level 2-bay NAS that targets home users looking to set up a multimedia entertainment solution (4K media transcoding and streaming) and those who just need a device to secure their data via their own personal cloud. Released back in January, the QNAP NAS comes in two models: TS-251D-4G and TS-251D-2G. Though the 2G ships with 2GB of RAM and the 4G with 4GB, they both can be expanded to a maximum of 8GB using the two DIMM slots.
Overall, the TS-251D is another familiar release from QNAP (which is a good thing), with specs and features you normally find with their consumer-grade NAS solutions. As such, it comes with an Intel Celeron J4005 dual-core 2.0GHz processor (with burst up to 2.7 GHz), up to 8GB of DDR4 RAM as we mentioned above, one 1-Gigabit LAN port, and supports both 2.5/3.5-inch HDDs and SSDs. It also comes equipped with two USB 3.0 ports, three USB 2.0 ports, an HDMI port, and a GbE RJ45 Ethernet port. It also comes with QNAP’s USB One Touch Copy button, which copies data from a USB device to the NAS and vice versa.
The PCIe expansion is the most important component of the NAS, as it allows users to add some flexibility to to the NAS and expand of its functionality. With it, users can add a QNAP QXG – 10GbE/5GbE network expansion card for a high-speed network environment; an M.2 SSD for caching; a compatible wireless adapter; or a USB 3.1 Gen 2 (10Gbps) card for speedy file transmission.
Like all QNAP devices, the TS-251D also features Intel AES-NI 256 hardware-accelerated encryption and snapshot support, the latter which allows for quick recovery of data when files accidentally get deleted, modified or altered due to a ransomware attack. Moreover, QuMagie, the company’s smart AI photo management application, groups similar photos together in albums using the technology’s integrated AI image recognition. This is certainly ideal for those who will be using the TS-251D as a file management system for all their media.
