Product information

Description

The TerraMaster D4-320 is a desktop disk array designed for home and home office use, providing a reliable and efficient storage expansion solution for data backup, media streaming, and central file management. Utilizing the USB 3.2 Gen2 protocol, this 4-bay enclosure delivers data transfer speeds of up to 10 Gbps and supports a massive total storage capacity of up to 88 TB using 3.5-inch or 2.5-inch SATA hard disk drives and solid-state drives. Featuring a stylish minimalist appearance, tool-free drive installation, and an intelligent temperature-controlled fan, it combines high-performance operation with quiet and convenient daily use.

Advantages

The device achieves a significant speed boost compared to previous generations, offering combined read and write speeds of up to 1,016 MB/s when fully populated. An innovative push-lock bracket design allows tool-free and rapid hard drive installation in just a few seconds while ensuring a secure connection. Advanced vibration damping and sound-absorbing panels reduce operating noise by up to 50%, maintaining standby noise levels below 21 dB(A) for a comfortable working environment. Intelligent disk sleep mode aligns operation with the host computer to minimize mechanical wear and extend drive lifespans. Furthermore, advanced power protection mechanisms instantly safeguard internal components against unstable voltages or incorrect power sources.

Suitable for

  • Home and home office data backup and central file archiving
  • Media streaming and large-scale digital asset storage
  • Expanding existing desktop or NAS storage capacity
  • Cross-platform file sharing across Windows, Mac, and Linux environments

When it may not be suitable

This enclosure does not feature built-in hardware RAID functionality and operates strictly in a single-drive mode out of the box, requiring third-party software tools for RAID configurations. It is also not suitable for users seeking a standalone network-attached storage device without a direct USB connection to a host computer or compatible NAS.

Key specifications

  • Supports up to four 3.5-inch or 2.5-inch SATA HDDs and SSDsMaximum individual drive capacity up to 22 TB, totaling up to 88 TB storage capacityUSB 3.2 Gen2 Type-C interface supporting transfer speeds up to 10 GbpsIntelligent temperature-controlled low-noise cooling fanPlug-and-play operation compatible with Windows, Mac, and Linux operating systems

How to use

Connect the disk array to your computer or compatible TerraMaster NAS using the included USB Type-C cable. Insert your SATA hard drives or solid-state drives into the tool-free brackets using the push-lock mechanism until securely fastened, without requiring any complex tools. The device operates on a plug-and-play basis without requiring custom driver installations. Power on the unit and begin transferring files, managing media libraries, or setting up scheduled automated backups through compatible software tools like TPC Backupper.

What to consider before purchase

  • Verify that your intended hard drives are listed on the official compatibility list to prevent connection or recognition issues
  • Confirm whether you require software-based RAID management, as the device itself does not provide hardware RAID arrays
  • Check available desk space and proximity to the workstation, keeping in mind the low-noise acoustic profile
  • Ensure your host system supports USB 3.2 Gen2 or compatible interfaces to achieve maximum data transfer speeds

Usage recommendations

Regularly consult the manufacturer hard drive compatibility list before adding new storage media, utilize third-party software for data redundancy if RAID is required, and install the TPC Backupper utility to automate scheduled data protection tasks for your Windows environment.
