Overview

The QNAP TS-133-14WD-US is designed to remove the biggest barrier to NAS adoption for home users: the initial setup. By shipping with a 4TB WD Red Plus drive already installed and configured, it lets you go from unboxing to centralized file access in minutes. The WD Red Plus line is purpose-built for NAS environments with optimized firmware for 24/7 operation, making it a sensible pairing for a device intended to run continuously. Once connected to your router via the single Gigabit Ethernet port, QNAP's QTS operating system provides a browser-based interface for configuring shared folders, automated backups from PCs and mobile devices, cloud synchronization, and basic media streaming.

Under the hood, the quad-core ARM Cortex-A55 processor clocked at 1.8GHz paired with 2GB of DDR4 RAM handles everyday NAS duties—file transfers, scheduled backups, and lightweight app hosting—without consuming much power or generating noticeable noise. That said, the hardware imposes clear boundaries. There is no option to add a second drive for RAID protection, the RAM cannot be upgraded, and the ARM architecture rules out hardware-accelerated media transcoding and heavier workloads. For users whose needs are straightforward—backing up family photos, sharing documents across devices, or streaming a personal media collection to a local player—the TS-133 delivers a clean, affordable solution. Users who anticipate growing beyond a single drive or needing more processing headroom should consider a multi-bay model from the outset.

Pros & Cons

👍 Pros

  • Pre-installed and pre-configured 4TB WD Red Plus drive eliminates the hassle of purchasing and setting up a separate hard drive.
  • Compact single-bay design is small and quiet enough for a home office shelf or living room.
  • ARM Cortex-A55 quad-core processor is energy-efficient, keeping power consumption and heat output low.
  • QNAP's QTS operating system provides a full-featured app ecosystem for backups, media streaming, and cloud sync.
  • Includes both USB 2.0 and USB 3.2 Gen 1 ports for connecting external storage or peripherals.

👎 Cons

  • Single drive bay means no on-device RAID redundancy—if the drive fails, data is lost without an external backup.
  • 2GB of non-expandable RAM limits multitasking and rules out running virtual machines or multiple Docker containers.
  • Only one Gigabit Ethernet port with no link aggregation or faster networking option constrains transfer speeds.
  • The ARM processor is underpowered for tasks like real-time media transcoding or running surveillance station with multiple cameras.
  • 4TB total capacity may fill up quickly for users with large media libraries or extensive backup needs.

Frequently Asked Questions

No. The 4TB WD Red Plus drive comes pre-installed and pre-configured, so you only need to connect the NAS to your network and power it on to begin using it.
No. The TS-133 has 2GB of DDR4 RAM that is soldered and not expandable.
No. This is a single-bay NAS, so it holds only one 3.5-inch drive. There is no option for RAID redundancy within this unit. For data protection, you would need to use an external backup strategy.
The TS-133 runs QNAP's QTS operating system, which supports file sharing, automated backups, media streaming, cloud sync, and a range of apps from the QNAP App Center. However, the ARM processor and 2GB RAM limit its ability to run resource-heavy applications like virtual machines or extensive Docker containers.
It connects via a single Gigabit Ethernet (RJ45) port to your router or switch.
