TerraMaster just released a new storage box called the D4-320U. This little powerhouse holds four drives yet takes up hardly any space. You can pack it with hard drives totaling 88 terabytes - that's enough room for thousands of movies or millions of documents. The box connects through super-fast USB 3.2 Gen 2 ports running at 10 gigabits per second. Small businesses, home users, and IT departments will love how much this compact unit does.
This storage device measures just 9.49 inches deep—half the size of regular rack gear. It weighs only 7 pounds but fits standard server racks without extra rails. You can place it almost anywhere—server rooms, closets, even tight office spaces. The small size makes it perfect for people who need big storage without giving up much room.
The D4-320U runs each drive separately by default, but you can use software to create RAID arrays if you want extra safety or speed. Tests show it reaches 1,016 megabytes per second with four WD Red hard drives. Even a single SSD hits 510 megabytes per second read speed. These speeds let you move large files quickly, whether you work with videos, photos, or business documents.
TerraMaster built this device to work perfectly with their NAS systems running TOS 5.1 or newer. You simply plug it into your existing NAS through USB to add more storage space. This makes growing your storage setup much easier than buying an entirely new system. The box works right away with Mac, Windows, Linux, TrueNAS, Unraid, and many other systems.
No drivers are needed—just plug it in and start using it. The package includes both USB-A to USB-C and USB-C to USB-C cables for connecting to almost any computer, TV, or server. These cables support all modern USB speeds plus Thunderbolt 3 and 4 connections, so you'll never struggle with compatibility issues.
Smart protection features keep your data safe from power problems. If the power goes out during normal use, the system remembers what it was doing and restarts automatically. If you shut it down properly before a power loss, it stays off when power returns. The drives also sleep when your computer sleeps, saving energy and making the drives last longer.
Cooling happens silently, thanks to a smart temperature-controlled fan. The fan adjusts its speed based on how hot the drives get, keeping noise levels down. The airflow design prevents hot spots inside the case, even when all four drives run at full speed for hours. Your drives stay protected without annoying fan noise.
TerraMaster includes backup software for Windows users. This program lets you schedule automatic backups of important files or entire disk partitions. You can set it to save only changed files each time, making backups faster after the first full backup. At the same time, TerraMaster also released a bigger five-bay model called the D5-310, giving customers choices based on their needs.
Both new products come with a two-year warranty when purchased through official TerraMaster stores or authorized dealers. The company designed these products to bridge the gap between personal and business storage needs. Anyone can buy these devices today and start expanding their storage capacity immediately.
