TerraMaster D9-320 review with nine drives for Mac users

In a world increasingly dominated by cloud storage solutions, the need for reliable, high-capacity external storage remains paramount. For users who require large amounts of data storage without sacrificing speed, the TerraMaster D9-320 presents a compelling option. This review delves into its features, performance, and overall value for Mac users looking to expand their digital storage capabilities.

While tech giants offer cloud solutions, many users still find themselves in need of local storage due to cost, speed, and privacy concerns. As a result, external storage solutions like the TerraMaster D9-320 have become essential for data-heavy tasks. This device caters to those who need expansive storage connected directly to their Mac, providing a bridge between traditional storage methods and modern demands.

Design and Build Quality of the TerraMaster D9-320

The physical design of the TerraMaster D9-320 is distinctive, setting it apart from more conventional NAS devices. Instead of a compact NAS aesthetic, it resembles more of a server tower housing multiple drive bays, which is a visual nod to its large capacity.

Measuring 13.1 inches in length, 11.6 inches in width, and 5.3 inches in height, the D9-320 is not a small enclosure. Its size is justified by the need to accommodate up to nine hard drives. The front features vented drive bays and locking mechanisms, ensuring that the drives are secure while allowing for airflow.

Key design features include:

• Multiple venting areas on the front and sides for effective heat dissipation.
• Drive bays that are easy to access, with intuitive ejection buttons.
• A robust build, ensuring durability over time.

Connectivity Options of the TerraMaster D9-320

Understanding the connectivity of the TerraMaster D9-320 helps clarify its intended use. This device is not designed to be a NAS or a docking station; instead, it serves as a direct attachment to a Mac, facilitating straightforward data transfer and storage.

Its connectivity features include:

• One USB Type-C 3.2 Gen 2 connection, which provides a speedy 10Gbps interface to the Mac.
• One USB Type-A port, also capable of 10Gbps, primarily used for daisy-chaining additional devices.

While the 10Gbps connection is satisfactory for many users, it may not be sufficient for those seeking top-tier performance in high-demand environments. The absence of Thunderbolt support is a drawback, especially for users who could benefit from faster data transfer rates.

Drive Compatibility and Support

The TerraMaster D9-320 is designed to accommodate a variety of drives, specifically SATA drives. It supports both 2.5-inch and 3.5-inch hard disk drives (HDDs) and solid-state drives (SSDs). This flexibility allows users to mix and match drives based on their needs for speed and storage capacity.

Notable features regarding drive support include:

• Tool-free drive sleds that allow for easy installation and removal.
• Hot-swappable functionality, enabling users to replace drives with minimal downtime.
• The capacity for up to nine drives, leading to a maximum theoretical storage of 216TB when using 24TB drives.

Performance Metrics of the TerraMaster D9-320

Performance is crucial when evaluating any storage solution. The TerraMaster D9-320 performs admirably in various configurations, although users should be aware of its inherent limitations.

According to TerraMaster, the unit can reach:

• Up to 510MB/s for a single SSD.
• Up to 1,016MB/s when filled with nine 8TB WD Red drives.

In real-world testing with mechanical drives, the unit demonstrated:

• 26 decibels at idle, increasing to 36 decibels under load.
• Read speeds averaging around 790MB/s and write speeds of approximately 720MB/s when configured in a striped RAID setup.

These measurements suggest that while the D9-320 is capable of handling significant data loads, users may encounter noise levels that could be distracting in quiet environments.

Storage Capacity and Use Cases

With the D9-320's capacity for extensive storage, it appeals to users who find NAS solutions too slow or expensive. This device is ideal for:

• Media professionals requiring large amounts of video or photo storage.
• Businesses that need to manage vast datasets securely.
• Individuals with extensive personal collections of digital media.

This level of storage could be overkill for the average Mac user; however, for those who genuinely require the extensive capacity, the TerraMaster D9-320 offers a robust solution. The main consideration remains the balance of purchasing multiple smaller drives versus investing in larger, more expensive options.

Advantages of the TerraMaster D9-320

When evaluating the TerraMaster D9-320, several advantages stand out:

• High Capacity: The ability to accommodate nine drives provides users with incredible storage potential.
• Durability: The build quality ensures that the unit can withstand regular use without compromising performance.

Drawbacks of the TerraMaster D9-320

Despite its strengths, the TerraMaster D9-320 has some notable drawbacks:

• Limited Connectivity: The lack of Thunderbolt support may restrict users seeking high-speed transfer options.
• Software RAID Limitations: Users need third-party software for more complex RAID setups beyond RAID 0 and RAID 1.
• Size: The substantial footprint may not be suitable for all desktop setups, and users should be cautious of its sharp corners.

Overall Rating and Where to Buy

The TerraMaster D9-320 achieves a rating of 3.5 out of 5. It is a solid option for users looking for high-capacity external storage, although it may not meet the needs of every user.

For those interested in purchasing the TerraMaster D9-320, it is available directly from TerraMaster and on Amazon, both priced at $499.99.
