U4-500Black4Bay, 1U, 6Core CPU, 8GB RAM 2 Years

Expert Review Analysis

The TerraMaster U4-500 is a compact 1U, 4‑bay rackmount NAS powered by an Intel Core i3‑1215U, 8 GB DDR5 RAM and dual 10 GbE ports, targeting SMBs that need high‑speed backup and large‑capacity storage. It supports up to 96 TB internal storage, NVMe cache acceleration, and offers robust RAID options with a low‑noise design.

✓ Best for: Small and medium businesses that need high‑speed backup, virtualization, 4K video production, or large‑scale storage (up to 96TB) in a compact 1U rackmount form factor. Ideal for office server rooms, machine‑rooms, or wall‑mounted cabinets where space is limited and dual 10GbE throughput is required.✗ Not ideal for: Home users or hobbyists who prefer a ready‑to‑use NAS with pre‑installed drives, require a low‑power footprint, or need more than four drive bays for massive raw capacity. Also not suited for environments that demand redundant power supplies.

Pros

✓Dual 10GbE ports provide up to 20Gbps aggregate bandwidth for fast backups and data transfers.
✓Compact 1U rackmount design with only 360mm depth fits easily into small cabinets or wall mounts.

Cloud Storage Devices

✓

High-performance Intel Core i3-1215U CPU combined with 8GB DDR5 RAM and NVMe cache delivers 2090 MB/s sequential writes and 450 MB/s 4K random IOPS.

✓Supports up to 96TB of internal storage across four hot‑swappable bays and offers online RAID expansion without downtime.

✓Built‑in Intel UHD Graphics with AES‑NI encryption and HDMI output enables secure media streaming and hardware‑accelerated encryption.

✓Three low‑noise system fans with smart speed control keep acoustic levels low even under full load.

Cons

✗The unit ships diskless, requiring users to purchase compatible HDDs or SSDs separately, adding to total cost.
✗Power consumption can reach approximately 35 W under full load, which may be higher than some competing low‑power NAS devices.
✗Drive tray labeling inconsistencies can cause confusion when installing high‑capacity drives such as 22TB models.
✗Included documentation is limited to thin paper instructions, which some users find insufficient for setup.
✗No built‑in redundant power supply, so a single PSU failure could lead to downtime.

From Expert Reviews

Praised by Experts

✓YouTube professional review highlighted secure drive trays with tabs that keep drives firmly in place even when inverted.
✓Reviewer praised the hot‑swappable bays and the ability to support large 22TB drives, demonstrating high‑capacity compatibility.
✓Professional coverage emphasized the rackmount versatility and compact 1U form factor suitable for SMB server rooms.
✓Official sources described the system as a powerful backup server delivering lightning‑fast throughput for business environments.

From User Reviews

Users Love

✓Everyday users commend the solid build quality and vibration‑secure drive trays that reduce noise during operation.
✓Users appreciate the low acoustic profile, noting that the NAS remains quiet even when all fans are running at high speed.
✓The dual 10GbE connectivity is praised for enabling rapid file transfers and efficient backup workflows in small offices.
✓Customers like the ability to expand storage via USB external enclosures, allowing total capacities beyond the internal 96TB limit.

Users Complain About

✗Some users report that the thin paper quick‑start guide lacks detailed instructions, making initial setup less straightforward.
✗A few customers mentioned confusion over drive size labeling, especially when installing 22TB drives that appear as 20TB due to GiB/GB conversion.
✗A minor complaint is the relatively high power draw during intensive read/write operations, which can increase electricity usage.

Expert Opinion

Professional reviewers, primarily a detailed YouTube re‑do review, praised the U4-500 for its secure, tab‑locked drive trays, hot‑swappable bays, and ability to handle very large drives such as 22TB models. They highlighted the compact 1U chassis, dual 10GbE networking and the system’s suitability as a powerful backup server for SMB environments, noting its strong performance and rackmount versatility. Official product messaging reinforces these points, positioning the device as a fast, versatile storage solution for business use.

What Users Say

Everyday users generally appreciate the sturdy construction, low noise operation, and fast 10GbE connectivity, often mentioning the vibration‑secure trays and quiet fans as positives. Common criticisms focus on the thin paper documentation, occasional drive‑size labeling confusion, and the higher power draw during heavy workloads. Overall sentiment is favorable for business users who value performance and compactness, with minor usability annoyances.

Common Complaints

Confusion caused by drive‑size labeling inconsistencies, thin paper quick‑start guide lacking detail, and relatively high power consumption under full load are the most frequently reported issues among users.

How It Compares

vs. Synology RS3621xs+

Advantages

✓TerraMaster’s 1U chassis is significantly smaller and lighter, fitting tighter rack spaces where Synology’s larger 2U unit may not.

Disadvantages

✗Only four drive bays versus Synology’s twelve, limiting maximum raw capacity and scalability.

Choose TerraMaster for compact, cost‑effective SMB deployments; choose Synology when you need many bays and higher raw capacity.

vs. QNAP TS-h1290FXU

Advantages

✓TerraMaster provides modern DDR5 memory and PCIe 4.0 NVMe cache in a smaller form factor, offering good performance for its size.

Disadvantages

✗QNAP offers more NVMe slots (four vs two) and higher sequential write speeds (~2500 MB/s) plus additional drive bays for larger storage pools.

Select TerraMaster for space‑constrained environments needing solid performance; select QNAP when maximum I/O throughput and expandability are top priorities.
