(burst up to 2.7 GHz) with 4GB RAM (1 x 4GB)
Overview
The TS-251D integrates secure data storage and multimedia entertainment into
one device. Featuring a PCIe slot, the TS-251D allows you to flexibly extend NAS
functionality and potential applications. You can enhance overall system
performance by installing a QNAP QM2 card for M.2 SSD caching/10GbE connectivity
combined with Qtier auto-tiering storage and installing a 10GbE/5GbE/2.5GbE
network expansion card. In addition, TS-251D can be used with QNAPs smart AI
photo management application, QuMagie, which integrates AI image recognition to
group similar photos together in album People, Things and Places. The TS-251D
features an HDMI slot to stream multimedia throughout your home. The TS-251D
supports dual-channel hardware decoding and transcoding, allowing you to view
NAS media files smoothly across various devices.
The PCIe port supports the installation of a 10GbE/5GbE/2.5GbE/ network
expansion card, a QM2 card, a USB 3.1 Gen 2 (10Gbps) card, or a wireless network
card.
Provide 4K media playback and online transcoding, while enabling cross-device
multimedia viewing via HDMI output or streaming applications.
Snapshots fully record the system status and data. If files are accidentally
deleted or modified, you can quickly restore previously-recorded data.
QNAP provides a wide range of multimedia applications. You can manage all
apps through the Multimedia Console to simplify management.
HBS backs up and synchronizes NAS data to other remote servers or cloud
storage, while QuDedup deduplicates data at the source to reduce network
bandwidth and storage space.
Use VJBOD (Virtual JBOD) to expand your storage capacity by using the unused
storage of other QNAP NAS. Connect up to two TR series USB storage
enclosure.
Intel Celeron J4005 Dual-Core Processor and AES-NI Hardware
Encryption
Powered by Intel Celeron J4005 dual-core 2.0 GHz processor (burst up to 2.7
GHz), DDR4 RAM (up to 8 GB), one Gigabit LAN port, and supports SATA 6Gb/s hard
drives, the TS-251D combines network expansion cards to create dependable
read/write performance. The TS-251D features Intel AES-NI 256
hardware-accelerated encryption for both full NAS volumes and shared folders,
boosting system performance while securing sensitive data stored in the
TS-251D.
Smart AI Photo Management
QuMagie integrates QuMagie Core AI image recognition technology for facial
recognition, subject identification, and geotagging photos. Similar photos are
categorized into People, Places, and Things albums. Moreover, QuMagie features a
built-in timeline scroll, customizable folder covers, iOS Live Photo display and
a powerful search tool, to provide you with the ultimate photo management and
image sharing solution.
Real-Time 4K Video Transcoding
Featuring advanced Intel UHD Graphics, the TS-251D supports dual-channel 4K
hardware decoding and real-time transcoding, allowing you to convert videos to
universal file formats that can be smoothly played across various devices*. You
can also watch high-quality 4K media files on an HDTV using the HDMI output or
with Plex Media Server to stream media files to mobile devices and media
streaming devices (including DLNA, Roku, Apple TV, Amazon Fire TV and
Chromecast). The QNAP RM-IR004 remote control (sold separately) can be
configured using QButton to customize individual button actions, providing a
more user-friendly NAS experience.
Multiple Ways To Enjoy Your Multimedia
QNAP provides a wide range of multimedia applications for you to easily enjoy
photos, music, and videos.
Multimedia Console consolidates all QTS multimedia applications into one app
for easier and centralized multimedia app management.
Cinema28 enables single-interface management of all media files and can
stream files to every connected device throughout your home.
Qmedia allows music, photos and videos to be effortlessly streamed to Android
TV, Apple TV, and Amazon Fire TV or set-top boxes.
Easy and Secure File Management
File Station centralizes files stored on your TS-251D and in the cloud. You
can easily upload files from your computer, drag and drop files between folders,
rename files, delete files, and configure file and folder permissions to prevent
unauthorized access. Moreover, with Microsoft Office Online you can open and
modify Microsoft Office documents stored on the TS-251D, without having to
download Word documents, Excel worksheets, and PowerPoint presentations from
your NAS to the PC. When it comes to sharing sensitive or confidential files on
the TS-251D, you can use File Station to enhance data security effectively by
encrypting files into a .qenc file, set a password, and then have file
recipients use QENC Decrypter to decrypt the sent file.
Multi-Point File Backup, Access, and Sync
The TS-251D stores data and files centrally, and supports file sharing
protocols, including SMB/CIFS, AFP and NFS for Windows, Mac, and Linux/UNIX
devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure,
high-capacity data center for file synchronization) any file uploaded to the
TS-251D becomes available for all linked devices, such as computers, laptops,
and mobile devices. Hybrid Backup Sync helps you easily backup or synchronize
data on the TS-251D to another QNAP NAS, remote servers, or cloud storage for
disaster recovery. Additionally, QuDedup technology greatly improves the
efficiency of multi-version backup to the destination storage, while optimizing
storage utilization. You can install the QuDedup Extract Tool on your computer
and restore deduplicated files to their normal status.
Protect Important Data With Snapshots
Snapshots help protect your data by fully recording the NAS system state and
metadata. You can use snapshots to quickly restore files to a
previously-recorded state when files are accidentally deleted or modified, or
when the system is compromised by ransomware. QNAP snapshots are block-based and
only record modified data. Not only does this save storage space, but also
reduces the time required to back up and restore data.
Extend NAS Functionality With The PCIe Slot
With a PCIe expansion Gen 2.0 x 4 slot, the TS-251D provides flexibility in
extending NAS functionality and potential applications. To optimize system
performance, install a QNAP QM2 card for M.2 SSD caching/10GbE connectivity and
use with Qtier tiered storage for optimal system performance. You can also use
the TS-251D as a wireless access point by installing a compatible QNAP
QWA-AC2600 wireless network card to create a wireless media streaming
environment. Moreover, by configuring the QXG-10GbE/5GbE network expansion
cards, you can upgrade your network to high-speed connectivity with an existing
CAT 5e cable. Alternatively, you can add an affordable QNAP QNA-UC5G1T USB 3.0
to 5GbE adapter to your TS-251D and laptop to enjoy higher network speeds, or
boost the USB connectivity of the TS-251D by installing a USB 3.1 Gen 2 (10Gbps)
card.
QVR Pro Safeguards Your Environment
QNAPs QVR Pro surveillance solution allows you to arrange dedicated,
independent storage space for surveillance data on the TS-251D and leverages
scalable storage advantages. With QVR Pro, camera management, storage space
allocation, camera live view, and playback is greatly simplified. You can also
use USB webcams as network cameras with the QUSBCam2 app, and remotely monitor
surveillance feeds anytime with QVR Pro Client mobile app.
