Qnap TS-451+-2G

Quad-core 64-bit Intel® Celeron® CPU for exceptional performance

The TS-451+ is powered by a 64-bit Intel® Celeron® quad-core 2.0GHz processor and has 2GB energy-efficient DDR3L RAM (upgradable to 8GB) and dual Gigabit LAN ports, delivering up to 225 MB/s read & write speeds with port trunking mode. The TS-451+ can also automatically increase the processor’s clock rate from 2.0GHz to 2.42GHz when needed for CPU-intensive tasks. The TS-451+ supports AES 256-bit volume & folder encryption with transfer speeds of up to 204 MB/s, boosting system performance & security while ensuring the safety of sensitive personal data stored in the TS-451+.

Tested in QNAP Lab. Figures could vary by environment.

Run additional operating systems on the TS-451+

The Virtualization Station transforms the TS-451+ into a 2-in-a-box NAS that can function as an all-in-one NAS and a virtualization platform that supports multiple operating systems, fast VM creation, VM backup & restoration, VM import/export, snapshot, Device Management for centrally managing VM, and enables desktop operations on web browsers. With the easy-to-use interface, you can centrally manage all of the VMs created on the TS-451+ with minimal effort. You can also download VMs on demand from online VM markets and import them to the TS-451+ without any complex procedures.

Real-time & offline video transcoding*

The TS-451+ delivers superior real-time video transcoding (up to 4K H.264) to convert your videos to formats that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for multiple devices to simultaneously view different videos stored on the TS-451+ with on-the-fly hardware accelerated transcoding, saving your time in converting videos to different formats for different devices.

With the benefits of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos via File Station, Video Station, or the Qfile app by selecting a pre-rendered lower-resolution video, saving system resources of the TS-451+ for other applications. The TS-451+ also allows you to set a dedicated folder for automatic video transcoding.

Qsirch – A smarter, faster way to search

Quickly and easily find documents, photos, videos, and music with Qsirch, QNAP’s new built-in NAS search application lets you find what you need by real-time, natural search. Simply type in as much as you know about what you are trying to find, including parts of the file name or even words/phrases in the document, and Qsirch will display a list of matches, complete with thumbnails, as you type. Qsirch even remembers your search history so you can quickly navigate to files you’ve previously searched for. Qsirch is a huge productivity boost that greatly reduces the amount of time spent looking for files on the NAS so you can focus on other tasks.

File Station integrated with cloud services

The web-based File Station enables you to easily upload, download, and manage files on your TS-451+ wherever there is an internet connection. Supporting file extraction, folder creation, and smart search for files and folders, the File Station also allows you to easily share files with colleagues and friends via unique URLs, email, and a shared space. What’s even better, you can also directly browse and transfer files between the TS-451+ and public cloud services like Google Drive™, Dropbox®, Microsoft® OneDrive, Box®, Yandex® Disk and Amazon® Cloud Drive through File Station, and view files with Office Online and Google Docs™ or directly open them with a Google Chrome™ office extension.

Disaster recovery solutions bring peace of mind

The TS-451+ offers various data recovery options. RTRR (Real-Time Remote Replication) supports real time and scheduled data backup to remote QNAP NAS or FTP servers and synchronizes files to remote folders from local folders with better backup efficiency. You can enjoy backup versioning to preserve a certain amount of versions, with options of simple versioning to schedule how many versions should be retained and for how long, or smart versioning with a rotation scheme that automatically replaces earlier backup versions. The TS-451+ also supports rsync protocol to back up data to remote servers 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™, Google Cloud Storage™, and more.
