Best For
Creative professionals needing fast 4K media access and transcoding, home‑lab enthusiasts running Docker or VMs, small businesses requiring secure RAID 5/6 backup with snapshots, streamers who want HDMI output and live rebroadcast, and users who value hardware flexibility (M.2, PCIe, dual 2.5 GbE).
Not Ideal For
Users who require built‑in 10 GbE networking, those who prefer completely tool‑free drive installation, buyers who prioritize the most polished OS experience, or environments where low power consumption and ultra‑quiet operation are critical.
Expert Opinion
Professional reviewers rate the AS6704T extremely highly, with PCMag giving it a perfect 5.0/5.0 “Exemplary” score for its blazing speeds, robust hardware and extensive app library. B&H echoes the performance praise, especially the 590 MB/s read/555 MB/s write figures. However, reviewers point out that the lack of native 10 GbE and a less polished OS keep it from overtaking Synology’s DS1522+, which secured the Editors’ Choice thanks to an extra bay and smoother software experience.
What Users Say
Everyday users love the AS6704T’s raw performance, flexible M.2 and 2.5 GbE options, and the breadth of apps that let them run Plex, Docker and VMs with ease. The device is frequently described as a solid value for creators and power‑users. Complaints focus on the need for tools to install drives, the occupied PCIe slot, occasional fan noise, and a UI that feels less refined than Synology’s DSM.
Common Complaints
Drive installation needs a screwdriver, the M.2 daughterboard blocks the PCIe slot for easy 10 GbE upgrades, fan noise can increase under load, power consumption is higher than some competitors, and the ADM UI is considered less refined than Synology’s DSM.
What People Are Saying
“high-performance design for intensive tasks like video editing”
“up to 590 MB/s read and 555 MB/s write speeds”

How It Compares
vs. Synology DiskStation DS1522+
Advantages
Disadvantages
Choose the DS1522+ if you need an extra bay and a more refined OS; pick the AS6704T for M.2 flexibility, HDMI 4K output and faster 2.5 GbE networking.
