The TS-251A provides the innovative USB QuickAccess port that allows you to quickly complete the first-time NAS installation and to then directly access files and data stored on the NAS. It also supports two additional transmission modes: Ethernet NAS mode and iSCSI SAN block-based mode. Combining USB QuickAccess, NAS and iSCSI-SAN into one box, the TS-251A is a powerful but easy-to-use storage solution ideal for backup, synchronization, remote access, and entertainment. It greatly helps to boost productivity and can meet the demands of photographers and audiovisual enthusiasts for direct, quick access to files. The TS-251A is powered by a high-performance 14nm Intel® Celeron® N3060 dual-core 1.6GHz processor, and supports 4K video playback and transcoding
The TS-251A features an innovative USB QuickAccess port that allows you to complete the first-time installation and setup of your TS-251A without requiring network connectivity. The files and data stored on the TS-251A can also be directly accessed by using Qfinder Pro* and a USB 3.0 A-Male to Micro B-Male cable or a USB 2.0 Micro B cable**. Furthermore, you can assign access rights to users for different folders to prevent unauthorized access to important files.
* QfinderPro and USB QuickAccess support Windows 8.0 (and above) and Mac OS X 10.7(and above). Other versions may require driver installation.
**A USB cable is not included.
Thanks to the intuitive user interface of QTS, your NAS experience is smarter, smoother and spectacular. 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 working efficiency. QTS breaks the barriers of devices, platforms, and geography to bring optimized cloud experiences and incorporates advanced features including volume/LUN snapshots, remote connections to public cloud services in File Station, multi-zone multimedia system, and more.
Qsync turns your TS-251A into a safe, large-capacity data center for file synchronization. Any file uploaded to the TS-251A will be made available for all linked devices, such as computers, laptops or mobile devices. Qsync is especially useful for frequent travelers to manage files and always have the most up-to-date files on different devices. Qsync provides multiple ways of file synchronization and group file sharing, greatly enhancing the flexibility of team projects and collaboration. It also supports centralized configuration, and allows you to remotely erase the Qsync folder on a lost device to avoid data breaches, and even restore it after you have retrieved the device.
Hybrid Backup Sync consolidates backup, restoration and synchronization functions into a single QTS application for you to easily transfer your data to local or remote QNAP NAS, to remote servers and to cloud storage spaces as a comprehensive data storage and disaster recovery plan. You can synchronize files between the TS-251A and cloud storage in real time – including Amazon® Drive, Google Drive™, Dropbox®, Microsoft OneDrive®, Yandex® Disk, and Box®, and back up files to Amazon® S3, Amazon® Glacier, Microsoft® Azure™, Google Cloud Storage™, OpenStack Swift and WebDAV cloud services. Hybrid Backup Sync can detect sparse files to avoid backing up unnecessary data, and supports file compression to save storage space. There are flexible settings for concurrent file processing and multi-threaded data transfer by splitting large files into smaller parts, greatly increasing the file transfer rate for greater work efficiency.
The TS-251A supports Qsirch, a proprietary search engine for quick file searching. In addition to previewing thumbnails, content abstract and keyword hints, Qsirch allows you to search through all of the .eml files stored on the TS-251A and use customized search criteria* such as date, size, sender and recipient. Qsirch even remembers your search history allowing you to quickly navigate to files you’ve previously searched for. You can also use the Google Chrome™ extension – Qsirch Helper – to search for files on your NAS when using Google Search™. Qsirch is a huge productivity boost that greatly reduces the time spent looking for files on the NAS, allowing you to focus on other tasks.
QmailAgent is an online email client that helps you manage multiple email accounts, allowing you to access all of your emails and to easily switch between different accounts. It provides complete functionality for composing, reading and organizing emails. You can even attach files, photos and documents from the TS-251A when composing emails. QmailAgent also allows iOS® and Android™ users to quickly check multiple email accounts with mobile devices, and to browse & send emails using the QmailAgent on their TS-251A. You can also use QmailAgent together with Qsirch, which supports powerful email search functions to search through all of the .eml files stored on the TS-251A to make managing and searching through massive quantities of emails much easier.
