Qnap TS-233-US 2-Bay Desktop NAS 2GB ARM Cortex-A55

Two-bay desktop NAS for personal cloud

The Qnap TS-233-US is a diskless network storage device with two SATA drive bays supporting 3.5-inch and 2.5-inch drives up to 44TB total capacity. An ARM Cortex-A55 quad-core processor running at 2.0GHz with 2GB of non-upgradable memory runs QTS 5.0.0 for file sharing, backup and multimedia streaming. One Gigabit Ethernet port and three USB ports provide local expansion and network access.

Suits home users wanting simple centralised storage

This unit fits households that need automatic photo backup, media streaming to TVs and remote file access without complex administration. Buyers who require hardware transcoding for high-bitrate video, virtualisation support or multi-gigabit networking should look at higher-specification models. The fixed 2GB memory also limits concurrent applications and Docker containers.

Single 1GbE port defines network throughput

All client traffic, replication and cloud sync pass through one RJ-45 interface limited to 1000Mbps. Aggregate read and write speeds will not exceed this link, so environments with heavy simultaneous users or large daily backups will saturate the connection. No additional network interfaces or PCIe expansion slots are present to alleviate the bottleneck.
