Intel® Celeron® J4125 quad-core 2.0 GHz processor (Bursts up to 2.7 GHz), 4 GB DDR4 memory (1 x 4 GB)

The TS-253D comes with two 2.5GbE RJ45 LAN ports that allow you to use existing CAT5e cables to upgrade network speeds from 1 Gigabit to 2.5 Gigabit. The dual 2.5GbE ports also support Port Trunking for up to 5 Gbps! By using QNAP’s N-BASET/Multi-Gig USB 3.2 Gen 1 to 5GbE adapter (Model name QNA-UC5G1T) or 5GbE PCIe expansion card (Model name QXG-5G1T-111C), your laptop or desktop computer can easily connect to 2.5GbE networks with the TS-253D to benefit from higher network speeds.

Upgrading your network shouldn’t break the bank, and 2.5GbE connectivity provides immediately noticeable improvements compared to standard 1GbE. The QSW-1105-5T is an unmanaged switch with five 2.5GbE ports (backwards compatible with 1G/100M) and supports CAT5e cables to connect multiple computers and NAS. The QSW-1105-5T is energy-saving, low-noise, plug-and-use, and supports loop detection and blocking to provide a simple and effective high-speed network environment.

The TS-253D is powered by an Intel® Celeron® J4125 quad-core 2.0 GHz processor (bursts up to 2.7 GHz), features up to 8 GB DDR4 memory, and supports SATA 6 Gb/s drives. The support of Intel® AES-NI encryption engine boosts encryption performance while also maintaining the security of your NAS data. You can flexibly install SSDs for cache acceleration to maximize network and storage performance for data-intensive applications.

• 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 their 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 1,024 snapshots per NAS.

Hybrid Backup Sync (HBS) consolidates backup, restoration and synchronization functions (using RTRR, Rsync, FTP, CIFS/SMB) for easily transferring data in the TS-253D to local, remote and cloud storage spaces (including Microsoft One Drive®, Google Drive™, Dropbox®, and more) as a comprehensive data storage and disaster recovery plan. Supporting QuDedup technology that eliminates duplicated data at the source, HBS reduces backup data size and speeds up future backup tasks. This is also beneficial for accelerating multi-version backups for greater protection against data loss.

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

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 (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 volume. This feature is perfect for IOPS-demanding applications including databases and virtualisation. The TS-453D also supports write-only cache to boost write-intensive applications.
• Qtier for auto-tiering - Qtier technology drives auto-tiered storage with continuous data optimisation 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.

The TS-253D perfectly 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 ideal 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.

The TS-253D centrally stores data and files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows®, Mac®, and Linux®/UNIX® networks. Coupled with the Qsync utility, any file uploaded to the TS-253D will be made available for all linked devices (such as computers, laptops and mobiles). You can sync shared folders and team folders for group file sharing to enhance the flexibility of team projects and collaboration. With the myQNAPcloud service, you can easily and securely connect to the TS-253D via the Internet for accessing, managing, and sharing NAS files. The Windows AD® and LDAP services enable system administrators to configure user permissions by using an existing Windows AD® server, LDAP server, or the TS-253D’s built-in LDAP service.

• Notification Centre - Consolidates all QTS system events, alerts, and notifications for smooth and easy NAS management, keeping you always informed of your NAS status.
• Security Counsellor - A security portal for checking weaknesses and providing recommendations for enhancing NAS security. It also integrates anti-virus and anti-malware scanning software.
• Qsirch - QNAP’s powerful, Google-like search tool for quickly finding specific images, music, videos, documents, and emails by keywords, color, and more search conditions.
