Built with dual 2.5GbE connectivity, a 2 GHz quad-core processor, AES-NI hardware encryption, and support for up to two 2.5" or 3.5" SATA III drives, the TS-253D 2-Bay NAS Enclosure from QNAP adds to your network storage capacity for daily backups, media serving, and file library archiving. The TS-253D supports up to 800 concurrent connections and includes an HDMI 2.0 port with real-time 4K transcoding to share 4096 x 2160 resolution videos to connected devices at 60 Hz. This NAS has a sequential file download speed of up to 295 MB/s and an upload speed and a 293 MB/s over a single 2.5GbE connection. Using both 2.5GbE ports boosts download and upload performance to 588 MB/s and 507 MB/s respectively.

Expand the TS-253D's capabilities using its PCIe 2.0 x4 slot, which allows you to install a 5GbE or 10GbE Ethernet adapter, a compatible M.2 solid-state drive for cache acceleration, or a 10 Gb/s USB 3.2 Gen 2 port. An optional 10GbE card maxes out download speeds at 983 MB/s with upload speeds of 512 MB/s. Adding an SSD for cache acceleration helps to optimize performance for data-intensive applications.

The TS-253D includes a 2.0 GHz Intel Celeron J4125 quad-core processor with 4GB of DDR4 memory and 4GB of flash storage to quickly run installed applications using the QTS 4.4.2 operating system. Drives can be configured in RAID 0, 1, JBOD, and Single mode. Two USB 3.2 Gen 1 Type-A ports and three USB 2.0 Type-A ports are included, allowing you to connect compatible peripherals such as external storage drives to share across the network. A 70mm fan helps to keep the enclosure operating at optimal temperatures.
General Features
2.5GbE Network Connection

The TS-253D features dual 2.5GbE RJ45 LAN ports that can transfer up to 295 MB/s over a single connection or 588 MB/s when both ports are in use.
Network Storage

You can install up to two 3.5" or 2.5" SATA III 6 Gb/s drives into the TS-253D, set to RAID 0, 1, JBOD, or Single configuration. Backup your data, share media across your network, and archive your file library. Your data is secured by an AES-NI encryption engine that is designed to maintain performance while keeping your data safe. Installing an optional solid-state acceleration cache helps to maximize performance for data-intensive applications.
Power and Performance

Featuring a 2.0 GHz Intel Celeron J4125 quad-core processor with up to 2.7 GHz burst speeds and 4GB of DDR4 memory, the TS-253D can load a variety of QNAP QTS applications while managing up to 800 concurrent connections.
Windows and Mac Backup

Use the license-free QNAP NetBak Replicator utility to back up and restore files from Windows computers. Apple's Time Machine is supported for backing up Mac computers.
Snapshots for Volume & LUN

Snapshots are essential for NAS data protection, and a block-level feature makes it a dependable data protection method in the face of growing ransomware threats. The TS-253D supports up to 256 snapshots per volume/LUN, and up to 1024 snapshots per NAS.
One 2.5GbE Is Better than Two 1GbE for Increasing HBS Backup Efficiency

With a single 2.5GbE connection, no complex link aggregation settings are required for speeds up to 312.5 MB/s, which easily beats a paired 1GbE connection. The TS-253D has two 2.5GbE ports, further doubling performance and increasing efficiency for versatile tasks.

Hybrid Backup Sync (HBS) consolidates backup and synchronization functions for easily transferring data from the TS-253D to local, remote, and cloud storage spaces. HBS also supports QuDedup technology which removes duplicated data at the source, further accelerating backup and restoration tasks over 2.5GbE connections.
Abundant I/O Capability with PCIe Expansion

The TS-253D features one PCIe 2.0 slot that allows for various expansion cards for expanding application potential.

5GbE/10GbE Network Card
Enable fast throughput for bandwidth-demanding tasks, such as virtualization, massive data transmission, and fast backup/restoration.

QM2 M.2 SSD/10GbE Card
Adds M.2 SSD caching or 10GbE connectivity to the NAS for optimized performance and bandwidth.

Wi-Fi 6 Wireless Adapter
Install a PCIe Wi-Fi 6 (802.11ax) network adapter, based on the Intel AX200, in your NAS to create a Wi-Fi 6 network environment.

Wireless Adapter
Turn your NAS into a wireless access point or a base station by installing a QNAP QWA-AC2600 wireless adapter and the WirelessAP Station app.
SSD Caching and Auto-Tiering Enable 24/7 Optimized Storage Efficiency

While SSD prices continue to fall, and SSD capacity and performance continue to increase, organizations can easily take advantage of SSD strengths. The TS-253D supports numerous SSD-aware features that significantly maximize NAS performance with high cost-effectiveness.

SSD Over-Provisioning
You can add additional SSD over-provisioning (1% ~60%) to avoid write amplification and improve SSD random write speeds and endurance. You can potentially attain enterprise-grade SSD performance levels from affordable consumer SSDs.

SSD Cache Acceleration
Enables SSD caching for increasing IOPS performance and reducing latency for storage volumes. This feature is good for IOPS-demanding applications including databases and virtualization. The TS-253D also supports write-only cache to boost write-intensive applications.

Qtier for Auto-Tiering
Qtier technology drives auto-tiered storage with continuous data optimization across high-performance SSDs and high-capacity HDDs based on access frequency. I/O-Aware Qtier can reserve a cache-like space in the SSD tiered to handle burst I/O in real time.
4K HDMI Display and Real-Time Video Transcoding

The TS-253D has an HDMI 2.0 port that supports 4K (4096 x 2160) 60 Hz output, allowing you to directly view multimedia content saved on the NAS on a bigger screen. The support of high-quality 4K video transcoding enables the NAS to convert videos to universal file formats that can be smoothly played on multiple devices. The TS-253D also can stream videos through DLNA, Chromecast, and more to satisfy versatile multimedia application needs. 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.

Note: The TS-253D's hardware provides hardware decoding, encoding, and transcoding capabilities. However, playback quality may vary due to factors including playback software, file formats, system usage, and available bandwidth.
Build a Plex Media Server

By installing Plex Media Server from App Center, setting up the Plex Media Server on your NAS is only a few minutes away. You can stream media files stored on the TS-253D to mobile devices and media streaming devices, including DLNA, Roku, Amazon Fire TV, and Google Chromecast.

Note: PlexPass is required for Plex Media Server hardware transcoding.
Move Business Data to the Cloud Flexibly and Economically

The TS-253D integrates NAS with mainstream cloud services. By deploying cloud storage gateways and enabling local caching on the NAS, you can seamlessly use the cloud for storage, backup, and data recovery with low-latency access, providing an innovative hybrid cloud experience.

HybridMount File-Based Cloud Gateway
Flexibly expand your storage capacity by connecting to cloud storage. You can leverage QTS apps to manage and edit your cloud files or multimedia files. HybridMount is good for file server online collaboration and file-level data analysis.

VJBOD Cloud Block-Based Cloud Gateway
VJBOD Cloud supports streamlined NAS backup to object cloud storage. The block-based data transmission uploads random data and large files to the cloud in blocks, and only transmits block-based volume or LUN changes, such as addition, modification, or deletion. This is ideal for enterprise-level applications with large file transfer requirements, such as databases, VM volumes, and videos.
All-in-One Server to Host Virtual Machines and Containers

Regardless of your virtualization needs, you can count on Virtualization Station and Container Station for complete virtualization support. You can use Network & Virtual Switch to allocate adequate physical network resources to virtual machines, containers, and the NAS to simplify network deployment.
