This article covers QNAP(キューナップ) TS-453D 2つの2.5GbE対応ポートとNAS機能を拡張できるPCIeスロットを1つ搭載 Intel Celeron クアッドコアプロセッサ採用のSMB向け4ベイNAS.

Overview

The QNAP TS-453D is a 4-bay NAS designed for small-to-medium businesses (SMBs) and power users. It is powered by an Intel Celeron J4125 quad-core processor (2.0 GHz base, 2.7 GHz burst) and comes with 4 GB of DDR4 memory (expandable to 8 GB). Its standout feature is dual 2.5GbE LAN ports, which can be combined via port trunking to deliver up to 5 Gbps of aggregate bandwidth. A PCIe Gen 2 x4 slot is also included, allowing you to add an M.2 SSD cache card or a 10GbE network adapter later. With HDMI 2.0 output (4K@60Hz) and real-time transcoding, the TS-453D doubles as a capable media server. It runs QNAP's QTS operating system, offering snapshot protection, cloud backup, and a wide range of apps. This NAS strikes a solid balance between performance, expandability, and price for its target audience.

Included accessories: 90W power adapter, Cat5e Ethernet cable, screws, and quick installation guide. Market positioning: a cost-effective mid-tier NAS with dual 2.5GbE and PCIe expandability. While it lacks the CPU power and memory ceiling of higher-end models like the TS-473A, it offers excellent value for file serving and media streaming in small offices or home labs.

Best Use Cases

SMB file server administrators: Dual 2.5GbE improves backup and file-sharing throughput. Port trunking provides redundancy. Snapshot protection guards against accidental deletions. Home media server enthusiasts: HDMI output and real-time transcoding let you stream 4K content directly to a TV via Plex or Emby without a separate client. Users who want future expandability: The PCIe slot allows adding M.2 SSD caching or a 10GbE card later, making this NAS a long-term investment. Budget-conscious 2.5GbE adopters: Compared to rivals like the Synology DS920+, the TS-453D offers two 2.5GbE ports and a PCIe slot at a similar price point, giving it an edge in connectivity and expansion.
