## Long 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.

How to use

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.
