QNAP TS-451+-2G

QNAP's smart home storage solution is a great-looking system with excellent hardware, superior performance, and a surprisingly affordable price tag. The Intel processor offers unmatched reliability and stability, while its four cores deliver maximum processing power. The NAS is excellently scalable, as the storage can be easily scaled up and expanded using four 2.5" or 3.5" drives. This creates an easy-to-use storage solution suitable for data backup, file synchronisation and sharing, remote access, and multimedia applications.

Key features

  • Run multiple Windows, Linux, Unix or Android based virtual machines with the Virtualization Station
  • Remote management for the true "10-foot experience"
  • Intuitive and modern QTS operating system
  • Transcode Full HD videos on-the-fly or offline
  • Support for DLNA multimedia library streaming
  • Up to ten-drive expansion with enclosure

Professional hardware

The system is powered by an efficient Intel Celeron quad-core processor clocked at 2GHz, which can be automatically overclocked to 2.42GHz under heavy load, allowing it to smoothly cope with performance spikes. The processor is connected to energy-efficient DDR3L operating memory with the SO-DIMM design you know from laptops. The network aspect is handled by dual Gigabit LAN ports delivering up to 2Gb/s speeds with port trunking mode. The disk controller supports the obligatory RAID 1,0 and JBOD technology with optional AES encryption and transfer speeds of up to 205MB/s, which ensures data security and fast transfer speeds. With an expansion enclosure, you can also expand the NAS capacity to up to twelve drives.

Intuitive operation

The modern QTS 4.2 system provides intuitive, easy-to-use smart home storage control. You don’t have to settle for just one system, either. Thanks to the virtualisation support, your NAS can be even more versatile. You can easily create virtual machines, back them up, and restore them, all through a simple web interface. Exclusive QVPC technology allows virtual machines direct access to the hardware of your home smart storage solution and perform multiple functions at the same time.

Made for multimedia

With HDMI connectivity, you can connect your NAS to any viewer, projector, or home cinema and enjoy 7.1-channel Full HD multimedia content - all of which can be controlled using the supplied infrared remote control. For mobile devices, it supports over-the-air streaming including transcoding the video to the required quality and format. For other multimedia devices, there is the ever-popular DLNA standard. And since technology marches on, the NAS also supports Google Drive, Dropbox, Microsoft OneDrive, and similar cloud based solutions.

Unusual features

Advanced features include the option to back up your data through NetBak Replicator or Apple Time Machine. The NAS also has number of unusual functions, such as the ability to host www servers, FTP servers, or VPN servers with L2TP/IPsec, OpenVPN, or PPTP support. The cherry on the cake is then the option of using the NAS as a professional surveillance solution.
