Direct access to files with the USB (Universal Serial Bus) Quick Access port The TS-451A features an innovative USB (Universal Serial Bus) 3.0 Quick Access port that means that you can complete the first-time installation & setup of your TS-451A without requiring network connectivity. The files & data stored on the TS-451A can also be directly accessed by using Qfinder Pro* & a USB (Universal Serial Bus) 3.0 A-Male to Micro B-Male cable or a USB (Universal Serial Bus) 2.0 Micro B cable**. Furthermore, you can assign access rights to users for different folders to prevent unauthorized access to important files. * Qfinder Pro & USB (Universal Serial Bus) Quick Access support Windows 8.0 (and above) & Mac OS X 10.7 (and above). Other versions may require driver installation. **A USB (Universal Serial Bus) cable is not included. USB (Universal Serial Bus) Quick Access/NAS/i SCSI SAN triple solution The TS-451A innovatively re-defines what NAS can do by providing a USB (Universal Serial Bus) 3.0 Quick Access/NAS/i SCSI SAN triple solution. It discards the restriction of conventional DAS that only allows connecting to one device, & 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.
