QNAP TS-253E TS-x53E Series 2-Bay Tower NAS

Compact Storage with a Clear Role in Your Business Give a small office, branch location or dedicated backup task its own organised storage platform. The QNAP TS-253E combines two SATA bays with an Intel Celeron J6412 processor, dual 2.5GbE networking and separate M.2 NVMe slots. Dual HDMI outputs add a local display option for supported applications. The compact enclosure keeps deployment practical where space is limited, while QNAP’s storage and backup tools let you build a consistent routine for shared files and important business information. Highlights Storage That Fits Your Work 2 hot-swappable SATA bays for compatible hard disks or SATA SSDs, with drives supplied separately. Two dedicated M.2 NVMe slots for SSD storage or supported cache configurations. A Faster Shared Workspace Two 2.5GbE ports for supported multi-link configurations or separate network connections. Intel Celeron J6412 quad-core processing with 8GB DDR4 memory supplied. Options Beyond File Sharing Dual HDMI outputs for supported local display and monitoring applications. QTS applications for backup, synchronisation, media and virtualised workloads. Key Features Storage with Room to Plan Two SATA bays keep the storage layout straightforward for a branch file server, backup destination or focused application. With two suitable drives, RAID 1 can maintain service after a single drive fails. The two M.2 slots offer a separate place for SSD workloads. Choose compatible disks and plan the required usable space after redundancy, snapshots and system reservations. Networking Built Around Shared Access Two 2.5GbE Ethernet ports help remove a common bottleneck when compatible computers and switches are ready for faster networking. Use them for supported port-trunking configurations or separate network connections. Combining links requires the appropriate network and client setup; it does not turn one ordinary 2.5GbE connection into a 5GbE connection. Actual file-transfer speed also depends on the drives, file sizes and workload. A Dedicated Place for SSD Workloads Two M.2 2280 PCIe Gen 3 x2 slots let you add compatible NVMe SSDs without occupying the SATA bays. Use supported SSD cache or storage-pool configurations to suit frequently accessed files and applications. QTS also offers Qtier for compatible tiered-storage arrangements. Select suitable SSDs and cooling for the workload, and power the NAS down before installing or removing M.2 storage. Keep Work Organised and Backups Deliberate Centralised shared folders give Windows, Mac and Linux users a common place for authorised files. Qsync helps keep working folders synchronised, while Hybrid Backup Sync can schedule copies to another NAS, supported cloud storage or a USB destination. Time Machine support provides a Mac backup option. Set permissions, retention and recovery checks deliberately so that a backup is useful when you need it. Choose the Operating System Before You Build QTS provides a familiar app-based environment for shared storage and everyday NAS tasks. QuTS hero is also supported for a ZFS-based deployment, with different storage features and memory requirements. It requires at least 8GB RAM, and inline deduplication requires at least 16GB. Changing between the systems erases and reinitialises storage, so make a complete external backup and follow the manufacturer’s migration procedure before switching. More Possibilities for Your Workspace Intel UHD Graphics and two HDMI 1.4b outputs supporting up to 3840 × 2160 at 30Hz provide options for supported local-display and media applications. Virtualization Station and Container Station can run suitable virtual machines or containers, subject to available memory and application requirements. Media codecs, guest operating systems and surveillance functions may need separate software or licences. Plan these workloads alongside file services rather than treating the NAS as an unlimited replacement for a dedicated server. Practical Connections and a Clear Upgrade Path The built-in networking and two M.2 slots cover the core connections in this compact platform. Supported USB expansion enclosures can provide an additional storage route; this model does not have a PCIe expansion-card slot. Two 10Gbps USB Type-A ports and USB One Touch Copy support convenient transfers to or from suitable external storage. Build Protection into the Routine RAID can help maintain access after a drive failure, and snapshots can help recover earlier file versions when configured appropriately. Neither replaces an independent backup. Keep the NAS and applications updated, use individual accounts and multi-factor authentication where supported, and avoid exposing administration directly to the internet. A separate, up-to-date copy of important files remains essential for hardware failure, accidental deletion and ransomware recovery. Surveillance with Clear Channel Entitlements Record compatible IP cameras with a supported QVR installation. QVR Pro includes eight recording channels. Current QVR Surveillance provides two standard channels plus six more after QNAP-ID activation, giving eight free channels in that application. Larger systems need the matching channel licences and a storage, network and workload assessment. Choose camera compatibility, bitrate, retention and playback requirements together; free channel counts are not a promise that every camera quality or workload will run at the same capacity. Summary The TS-253E combines compact two-bay storage with dual 2.5GbE, separate NVMe slots and dual local-display outputs. It is a focused option for business files, backups or supported monitoring applications in a small office or branch. Choose compatible drives, confirm the memory configuration before an upgrade and keep important data in a separate backup as well as on the NAS. Frequently Asked Questions Are Hard Disks or SSDs Included?ExpandCollapse No. The TS-253E is supplied as a diskless NAS. Choose compatible 3.5-inch SATA hard disks or 2.5-inch SATA SSDs for the main bays, and compatible M.2 2280 NVMe SSDs if required. Check the exact drive model against QNAP’s compatibility list. Storage, optional expansion hardware and any additional software licences are separate. Can the M.2 Slots Be Used for Storage as Well as Cache?ExpandCollapse Yes. Supported M.2 NVMe SSDs can be used for a storage pool or an appropriate cache configuration, depending on the operating system and setup. QTS also supports compatible Qtier arrangements. M.2 drives are not hot-swappable; shut the NAS down before installation or removal and use suitable cooling. Can I Upgrade the Memory?ExpandCollapse The supplied configuration has 8GB DDR4 memory. Current QNAP hardware specifications describe two SODIMM slots supporting up to 16GB using two matching 8GB modules. Earlier hardware and manuals include non-expandable configurations, so confirm the actual unit’s memory slots before ordering an upgrade. Use QNAP-supported modules matched to that hardware. Can I Change Between QTS and QuTS hero?ExpandCollapse Yes, this model supports both operating systems, with QTS as the default. The change erases and reinitialises NAS storage. Make a complete backup outside the NAS, follow the current manufacturer procedure, then restore the data. QuTS hero needs at least 8GB RAM, with at least 16GB for inline deduplication; application features and storage layouts differ between the systems. Does RAID Replace a Backup?ExpandCollapse No. RAID is intended to improve availability after certain drive failures. It does not provide a separate copy when files are deleted, encrypted by ransomware or lost with the NAS itself. Use snapshots where appropriate, and keep a current independent backup on another device or service. Check that important files can actually be restored. How Many Camera Channels Are Included?ExpandCollapse QVR Pro includes eight camera-recording channels. Current QVR Surveillance starts with two standard channels; link the NAS to QNAP ID and activate the additional six to use eight at no channel charge. These are separate application entitlements, not sixteen licences for one recorder. Additional channels require matching licences and workload sizing. QVR Pro Client playback beyond fourteen days requires Gold or Unlimited Playback; that rule does not itself delete older recordings. Read more
