The QNAP TS-253A Two-Bay NAS Enclosure runs on the QTS 4.2 operating system and is able to function as a NAS server for data backup, file archiving and synchronization, remote access, and home entertainment. It is designed for SMB users and is compatible with Windows, Mac, Linux, and UNIX systems. The TS-253A is also able to perform on-the-fly and offline video transcoding; including Full HD 1920x1080 content and playback of 4K content with 7.1 channel surround sound via the HDMI ports.

The TS-253A is powered by a 1.6 GHz Intel Celeron N3150 processor that comes with four cores so you can run multiple functions simultaneously. The CPU can also achieve speeds of up to 2.08 GHz, the built-in 8GB of DDR3L RAM allows quick access to frequently-used files and programs, and network connectivity is achieved via two Gigabit Ethernet ports.

This 2-bay enclosure has the ability to natively house both 3.5" or 2.5" SATA III hard drives or SSD drives. In terms of data redundancy, a variety of RAID modes are supported including 0, 1, single disk, and JBOD. Read speeds of the TS-253A can reach up to 224 MB/s when configured in RAID 0. Additionally, data can be protected with AES 256-bit encryption while keeping the same read speeds.

QNAP has equipped this NAS enclosure with two HDMI ports along with four USB 3.0 ports. You may connect up to two displays as well as a keyboard and a mouse to control this NAS without the need of another computer. Furthermore, the two HDMI ports utilize the visual performance of integrated Intel HD Graphics to deliver 4K resolutions.

The TS-253A supports data recovery and redundancy options. In addition to backup support on Windows and Mac, it offers real time or scheduled data backup to a remote NAS or FTP server as well as rsync to back up to another remote server on a scheduled basis, such as cloud storage.

Performance
Powered by a 14nm quad-core Intel Celeron N3150 1.6 GHz processor with 8GB DDR3L-1600 RAM, coupled with the support of SATA III, 2 Gigabit LAN ports, the TS-253A is a NAS that delivers up to 224 MB/s read speeds. The TS-253A can automatically increase the processor's clock rate from 1.6 GHz to 2.08 GHz when performing CPU-intensive tasks. The TS-253A features Intel AES-NI hardware-accelerated encryption engine to drive transfer speeds of up to 224 MB/s with AES 256-bit encryption for both full NAS volume and shared folders, boosting system performance and security while ensuring the safety of sensitive business data stored in the TS-253A.
Offline 4K Video Transcoding
Featuring 8th-generation Intel HD Graphics, the TS-253A supports 4K (H.264) hardware decoding and delivers real-time 4K (H.264) and 1080p video transcoding to convert videos to universal formats that can be smoothly played on PCs, mobile devices, and Smart TVs. With offline transcoding, you can connect using a low-speed Internet connection and still enjoy smooth video playback via File Station, Video Station, and the Qfile mobile app by selecting a pre-rendered lower resolution video. The TS-253A also allows you to set a dedicated folder for automatic video transcoding.
QTS 4.2 Operating System
The QNAP operating system offers an intuitive user interface so your NAS experience is smarter and smoother. Its modern flat design streamlines loading times, and the intelligent desktop allows you to find desired functions quickly, create desktop shortcuts or group shortcuts, monitor important system information on a real-time basis, and open multiple application windows to run multiple tasks concurrently, bringing greater operating efficiency.
Disaster Recovery
The TS-253A offers various data recovery options. RTRR (Real-Time Remote Replication) supports real-time or scheduled data backup to a remote QNAP NAS or FTP server and synchronizes files to a remote folder from a local folder with better backup efficiency. The TS-253A also supports the rsync protocol to back up data to another remote server on a scheduled basis. Data can also be backed up to and restored from a range of cloud storage services, including Amazon S3, Amazon Glacier, Microsoft Azure, ElephantDrive, Dropbox, Google Drive, and Google Cloud Storage.
Snapshot
The QTS Storage Manager app lets you easily restore data on the TS-253A back to any point in time in the event of important data loss. You can take snapshots for both volumes and LUN (up to 256 snapshots per volume or LUN and maximum 1024 snapshots per NAS), efficiently replicate volume/LUN snapshots via Snapshot Replica to remote servers by copying only the changes made, and quickly clone a volume /LUN snapshot as a local volume without interrupting the current system operation. You can even set up the system to automatically take a snapshot of the volume before backup via RTRR/rsync, even when the file is opened.
Virtualized Environments
The TS-253A is also an iSCSI/ IP-SAN storage device that supports VMware and Citrix, and is compatible with Microsoft Hyper-V and Windows Server 2012, benefiting flexible deployment and management in virtualization environments. The TS-253A supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and supports QNAP vSphere Client plug-in and QNAP SMI-S provider with enhanced operational efficiency and management in virtualization applications.
Server Virtualization
With the support of QNAP's VM hypervisor, Virtualization Station allows you to host virtual machines on your NAS and access them via a web browser or VNC. Virtualization Station further uses SDN (Software-defined Networks) which allows the TS-253A and VMs to share the same LAN port. No longer constrained by physical network performance, high-speed Virtual Switches increases the data transfer between VMs as well as between VMs and NAS through the internal interface.

This NAS also features Container technology for server virtualization. QNAP's Container Station integrates LXC and Docker lightweight virtualization technologies, allowing you to operate multiple isolated Linux systems on the TS-253A as well as download apps from the built-in Docker Hub Registry. Container Station also supports the Online Document app, which allows you to directly view, edit, and store files of various types anytime on your NAS, including Office documents, images, and text files.
Cross-Platform File Sharing, Centralized Data Storage
The TS-253A supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, Linux/UNIX networks. Data, logs, and ISO images of CDs and DVDs can be centrally stored on the TS-253A and protected by an integrated antivirus solution. The Windows AD and LDAP services enable system administrators to configure user permissions by using an existing Windows AD server, LDAP server, or built-in LDAP service. The TS-253A supports SAMBA v4 and can act as a Windows domain controller to manage privilege settings.
USB 3.0 Port
The front-panel USB 3.0 port of the TS-253A features a one-touch-copy function for you to instantly back up data from external drives to the TS-253A with just one click, or alternatively to back up data from the TS-253A to external drives.
HDMI Connectivity
With HDMI connectivity, you can connect the TS-253A to a HDTV or an A/V receiver to enjoy your multimedia content and 4K H.264 videos with the best audio/visual experience. The included QNAP remote control lets you control the playback of your content. You can also turn your mobile devices into remote controls by installing the Qremote app.

The TS-253A comes with dual HDMI outputs for using two monitors in either a "mirrored" or "extended" desktop configuration. While mirroring displays the same content on both displays, extended desktop mode allows users to display applications over two displays for improved multitasking convenience and productivity.
Dual Microphones Inputs and Line Out Function
The TS-253A has two 1/4" (6.3mm) microphone jacks for connecting up to two dynamic microphones. Compared with the average reception quality of USB microphone, the TS-253A offers a clearer reception quality as it is equipped with a 20-bit analog-to-digital converter (ADC). On top of that, the TS-253A has a 24-bit digital to analog converter (DAC) that can send audio signals via the line-out jack to your amplifier and deliver clearer stereo sound.
Easily Expand Storage Capacity
The TS-253A supports online capacity expansion for archiving rapidly-growing data by connecting an optional QNAP expansion enclosure. With the QNAP scale-up solution, the raw storage capacity can be expanded on demand, making the TS-253A a suitable file center with large storage capacity for storage-intensive business applications such as video surveillance, data archiving, TV broadcast storage, and more.

With the support of QJBOD Express, you can just connect a large capacity QNAP expansion enclosure to the TS-253A and migrate data to another NAS through the JBOD enclosure without network connectivity.
Downloadable Software Apps
The built-in App Center provides various install-on-demand apps developed by QNAP and third-party developers, including tools for backup/sync, business, content management, communications, download, entertainment, and more. It is also a centralized location for managing and updating installed apps. You can directly update the installed applications in the App Center once the updated version is released.
