Direct access to files with the USB QuickAccess port
The TS-451A features an innovative USB QuickAccess port that allows you to complete the first-time installation and setup of your TS-451A without requiring network connectivity. The files and data stored on the TS-451A 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.

USB QuickAccess/NAS/iSCSI SAN triple solution
The TS-451A innovatively re-defines what NAS can do by providing a USB QuickAccess/NAS/iSCSI SAN triple solution. It discards the restriction of conventional DAS that only allows connecting to one device, and breaks the cost barrier for a high-speed Ethernet solution. The TS-451A’s three data transmission modes not only work independently, but they also can simultaneously run with no bandwidth interference, allowing you to multi-task with utmost productivity.
USB QuickAccess Mode
You can instantly access files and data stored on the TS-451A by connecting a PC/Mac to its USB QuickAccess port and by using the Qfinder Pro application. To balance security and convenience needs, this method provides three access authentication modes. These settings can be easily configured in Network and Virtual Switch in the QTS management interface:
The TS-451A’s USB mode is helpful for users that handle large volumes of media files on a daily basis. It provides an extremely convenient and fast solution for users to store and backup data on their computers or to access data on their NAS. With the USB mode the TS-451A is plug and use without compromising convenience or safety.
Ethernet NAS mode
The TS-451A features Ethernet networking for flexible and simultaneous file sharing across multiple devices, using SMB/CIFS, NFS and AFP protocols for sharing across Windows, Mac and Linux/UNIX networks. Use Qfinder Pro to find the TS-451A's Ethernet IP address to connect to it.
iSCSI SAN block-based mode
The TS-451A supports iSCSI SAN. After creating an iSCSI target on the TS-451A, you can access the iSCSI with your computer* using the NAS IP.
*iSCSI initiator for Mac: ATTO Xtend SAN or SNS globalSAN; for Windows: Microsoft iSCSI initiator

Superior 4K video transcoding
Featuring advanced 8th-generation Intel® HD Graphics, the TS-451A supports 4K H.264 hardware decoding and delivers superior real-time 4K and 1080p video transcoding to convert videos to universal formats that can be smoothly played on PCs, mobile devices and Smart TVs*. With offline transcoding, even when you can only connect using a low-speed Internet connection, you can still enjoy smooth video playback via File Station, Video Station, and the Qfile mobile app by selecting a pre-rendered lower resolution video. The TS-451A also allows you to set a dedicated folder for automatic video transcoding.
* Supported video formats depend on the hardware and software specifications of the devices.
Playback capability and quality may vary due to factors including the original file formats/quality, hardware and software limitations, and output devices.
