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:

“All NAS Users” (default): A NAS username and password are required to use QuickAccess to access data stored on the NAS.
“Everyone”: Allows everyone to access data stored on the NAS using QuickAccess with no username or password required.“Selected Users and Groups”: Only authorized users/groups can use QuickAccess to access data stored on the NAS (a username or password is also required).
