More raw power and ports than the Synology equivalents — if you like options and don’t mind busier software.
Best for: Tinkerers & media users. Price: ~£480 (diskless, 4-bay).
QNAP’s TS-464 throws more hardware at you for the money: a quick Intel chip with hardware transcoding, 2.5GbE networking, and NVMe slots. As a backup target and a media server, it’s a lot of box.
Speed and expandability. If you want your backup NAS to double as a Plex server, this handles both without breaking a sweat.
QTS is more cluttered than Synology’s DSM, and QNAP has had more security headlines — so keep it patched and never expose it directly to the internet.
People who want power, transcoding and expandability, and are happy to tinker.
Anyone who wants the calmest, simplest NAS experience — that’s Synology.
