**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).
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.
Enjoy media freely with multi-zone multimedia controls

Use NAS to expand NAS capacity with Virtual JBOD
Besides using physical storage expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD that allows you to expand the storage of a QNAP NAS by using unused storage from other QNAP NAS units. You can mount this storage space to the TS-451A as virtual disks and create virtual storage pools and volumes for NAS functions such as creating and reverting snapshots, indexing multimedia files into the media library, and even creating iSCSI LUNs. VJBOD supports 10GbE/40GbE connections and port trunking (link aggregation with multiple LAN ports) that increase the performance and reliability of your VJBOD storage.
*Remote QNAP NAS must support iSCSI and Storage Pools and use QTS 4.2.1 (or newer). Up to 8 remote NAS units can be mounted.

Connect a QNAP expansion enclosure to expand storage capacity easily
The TS-451A supports online capacity expansion for archiving rapidly-growing data by connecting a QNAP expansion enclosure. With the QNAP scale-up solution, the raw storage capacity can be expanded on demand, making the TS-451A an ideal file center with large storage capacity, especially useful for data-intensive applications.
With the support of QJBOD Express (JBOD enclosures roaming)*, you can just connect a large capacity QNAP expansion enclosure to the TS-451A, and migrate data to another NAS through the JBOD enclosure without needing a network connection.
The maximum raw storage capacity available by connecting a QNAP expansion enclosure:
|Turbo NAS Model||RAID Expansion Enclosure||No. of RAID Expansion Enclosure||Total HDD No. (NAS + Enclosure)||Max. Raw Capacity (TB)**|
*RAID groups of storage pools cannot cross multiple enclosures.
**The maximum capacity is calculated by using 8TB HDDs.
