External reviews of QNAP TS-451+-2G
  • QNAP TS-451+ & QTS 4.2


    • High performance
    • Strong CPU (for a NAS) that consumes very little power
    • Silent operation
    • Low power consumption
    • It runs one of the best operating systems for NAS servers
    • Support for up to 8 GB of RAM (which will definitely suffice for home use)
    • Two Ethernet ports that can be teamed
    • Support for four hot-swap disks
    • HDMI port
    • Quality power brick
    • Remote control included with the NAS
    • Rich multimedia capabilities
    • Supports all popular RAID levels
    • Front USB 3.0 port
    • Lots of optional packages and apps for smartphones
    • Comes with licenses for two camera-recording channels and supports up to 40

    • Price
    • The price gap between the 8G and 2G models is huge
    • Plastic trays that don't feature locks or sound-dampening materials
    • Would like to see shorter boot and restart times

    The CPU and RAM upgrades result in a significant performance improvement, and only in terms of noise output does the TS-451+ fall short of its predecessor, the difference very small. The TS-451+ obviously targets enthusiast home users who will use it as a multimedia player and a NAS server, which is clearly shown by the fact that QNAP includes an IR remote control in the bundle. The TS-451+ with 8 GB of RAM I evaluated performed amazingly with open file transfers; however, performance took a significant hit with encrypted files. The Intel J1900 CPU QNAP chose for this NAS doesn't support Intel's AES New Instruction set, making it the bottleneck with file encryption enabled. That said, most home users don't need encryption and won't care about the lack of AES NI support. The TS-451+ consumed very little power, which is mostly due to its incredibly efficient CPU. The CPU's low TDP also means it does not require active cooling, so the only fan is the one in the rear, mainly responsible for removing any heat the HDDs generate. There is the good selection of components for a home-centric NAS server and the most excellent QTS OS, which, in its most recent iteration, 4.2, has reached new levels of usability, performance, and reliability. The QTS OS is currently among the best when it comes to NAS servers offering an intuitive interface that will help every user, experienced or not, in exploiting the NAS server's capabilities properly.
