PRICE - 7/10
VALUE - 8/10

👍🏻Very compact chassis design, despite large storage potential
👍🏻A BIG jump in hardware and scale from the QNAP TS-451D
👍🏻Easily one of the most hardware-packed SMB/Mid-range 2-Bay on the market
👍🏻HDMI 2.1 Support is fantastically future-proof!
👍🏻m.2 NVMe SSD Bays AND a PCIe Upgrade Slot (no need to choose one upgrade path)
👍🏻8x Included Camera Licenses
👍🏻Includes Anti-virus, Firewall Tool, VPN client tools, Malware Remover, network manager and Security Councilor Tool
👍🏻3 Different Container/VM tools that also feature image download centers
👍🏻10Gb/s (1,000MB/s) USB Ports will be incredibly useful
👍🏻Large range of expansion options in the TR/TL series in 2, 4, 6, 8 and 12 Bays
👎🏻The PCIe Slot is PCIe 3x2 and the M.2 SSD Bays are PCIe 3x1 (likely limitations of all this H/W on a Celeron+chipset
👎🏻HD Station application needs more updates by the brand
👎🏻Base 2GB Memory is quite small!
👎🏻Software can be a little inconsistent under excessive use and features a steeper learning curve than Synology

ASUSTOR provides their own ADM server software platform with all of their solutions and although it is not quite as advanced as offerings from most expensive NAS solutions in the market, it still arrives with a huge range of applications, services and is accessible via a web browser, mobile applications and desktop client tools. Their latest revision of this software is remarkably responsive and this alongside a number of their solutions also arriving with HDMI support means that you have a wide range of ways in which to access the data on your Asustor NAS in a tailored and appropriate way. The majority of their NAS solutions also arrive with BTRFS support too, as well as possibly the widest support in the market for 3rd party tools available in their application center.
