TerraMaster D5-320H: The Ultimate 2+3 RAID NAS Solution (D5 Hybird)

If you’re in search of the perfect NAS solution for your home or small office, look no further than the TerraMaster D5-320H. This innovative 2-bay NAS with 3 NVMe slots offers a unique blend of versatility, performance, and reliability that makes it a standout choice for all your storage needs.

Hybrid Storage at Its Best

The D5-320H breaks new ground with its 2+3 RAID configuration, which lets you combine the massive storage capacity of 3.5″ SATA HDDs with the lightning-fast performance of M.2 2280 NVMe SSDs. It’s the best of both worlds, making it ideal for those who need to store both frequently accessed data and less-used archives. Plus, with TerraMaster’s TPC Backupper backup software, you can seamlessly schedule backups of your hot data to the HDDs, ensuring your crucial information is secure.

Supercharged Transfer Speeds

With the D5-320H, you’ll experience blazing-fast data transfers thanks to its USB 3.2 Gen2 protocol, providing a staggering 10Gbps of bandwidth. This means you can achieve read speeds of up to 980MB/s using M.2 SSDs, a remarkable 1075MB/s with SATA SSDs (in RAID 0), and a still impressive 521MB/s with HDDs (in RAID 0). That’s the kind of speed that will have your data flying back and forth without a hitch.

Exceptional Compatibility

The D5-320H boasts a USB Type-C interface, ensuring top-notch compatibility with a variety of protocols, including USB 3.0, USB 3.1, USB 3.2, USB4, Thunderbolt 3, and Thunderbolt 4. A 1m USB Type-C cable is included, making setup a breeze. Whether you’re on Windows, macOS, or Linux, the D5-320H has got you covered.

Compact Yet Capacious

Despite its modest size (measuring 222 x 119 x 154 mm), the D5-320H can hold up to 5 disks, supporting various types, including 3.5″ SATA HDDs, 2.5″ SATA HDDs/SSDs, and M.2 2280 NVMe SSDs (M Key/B&M key). This little beast can house up to 22TB HDD or up to 8TB NVMe M.2 SSD, offering a total storage capacity of up to 68TB – a perfect blend of compactness and capacity.

2+3 Array Mode

TerraMaster’s unique 2+3 array mode empowers you to configure different RAID modes for the SATA HDDs/SSDs, such as RAID 0, RAID 1, JBOD, and Single Disk, catering to your specific cold data storage requirements. The three NVMe M.2 SSDs are designed for single-disk mode, making them perfect for hot data with the fastest transfer speeds.

Tool-Free Disk Replacement

The D5-320H simplifies hard disk replacement with its tool-free hard disk tray. Installation and removal take less than 10 seconds. TerraMaster’s Push-Lock design automatically secures the hard disk on insertion, preventing any unplanned disconnections.

Effortless M.2 SSD Installation

TerraMaster has thoughtfully included a side sliding cover for easy M.2 SSD installation and removal. Additionally, hand-tightened screws make SSD installation a 5-second task.

Intelligent Hard Disk Sleep

The D5-320H supports hard disk sleep mode, synchronizing with your computer’s sleep mode to reduce power consumption and extend the lifespan of your hard disks.

Enhanced Power Protection

Advanced power protection technology safeguards the D5-320H and your hard disks from damage in case of an incorrect power supply connection.

Effective Heat Dissipation

The D5-320H features an intelligent temperature-controlled fan that adapts its speed to hard disk temperature, ensuring optimal operating conditions. Dedicated ventilation for M.2 SSDs enhances heat management for hybrid storage applications.

Whisper-Quiet Operation

TerraMaster engineers have gone to great lengths to minimize noise levels. The result is a 50% reduction in noise compared to the previous generation, with a mere 19dB(A) when in standby mode, making it an excellent choice for quiet office environments.

In conclusion, the TerraMaster D5-320H stands as a remarkable and innovative 2+3 RAID NAS solution that combines the best of both worlds. With its hybrid storage, high-speed transfers, and impressive features, it’s the perfect companion for your storage needs. Get ready to experience the future of NAS technology.
