Product description

• QNAP TS-451+ 4-Bay Home and SOHO NAS Server Built around the need for increasing amounts of data storage, sharing, and multimedia processing, the TS-451+ 4-Bay Home and SOHO NAS Server from QNAP provides a high-performance scalable storage solution for professional users. The TS-451+ runs the QTS 4.2 operating system and provides all-in-one server functionalities as well as features including Virtualization Station, which allows users to run multiple Windows, Linux, UNIX, and Android-based virtual machines. It is also able to operate multiple isolated Linux systems and download containerized apps with Container Station, play 1080p videos and multi-channel audio via HDMI, transcode Full HD videos on-the-fly or offline, stream multimedia files via DLNA, AirPlay, Chromecast, and Bluetooth, search efficiently using Qsirch, use the UX-800P expansion enclosure to increase the NAS's raw capacity, and more.
  
  The TS-451+ is powered by a 2.0 GHz Intel Celeron Quad-Core processor that features a boost speed of up to 2.42 GHz. The built-in 2GB of DDR3L RAM, which may be expanded up to 8GB, and the 512MB of flash memory allow quick access to frequently-used files and programs. Network connectivity is achieved via the 2 x Gigabit Ethernet ports. A variety of RAID modes are also supported, including RAID 0,1, 5, 5 + hot spare, 6, 10, which offer data redundancy, speed, or a combination of both. There is also the option to set the TS-451+ in single disk or JBOD mode if you don't need RAID functionality.
  
  This 4-bay enclosure has the ability to natively house both 3.5" or 2.5" SATA III & SATA II hard drives or SSD drives. To support both drive formats, screws are included to accommodate both drive sizes. Read speeds can reach up to 225 MB/s and write speeds can reach up to 224 MB/s, while data transfer speeds with AES 256-bit encryption can reach read speeds of up to 204 MB/s and write speeds of up to 158 MB/s. Using the two USB 3.0 and two USB 2.0 ports, this QNAP can be connected to other QNAP devices, such as the UX-500P and UX-800P expansion enclosures, as well as other external drives.
