Features TerraMaster d5-310

1. Flexible Hardware RAID Support

The D5‑310 includes a dedicated physical RAID mode selector on the enclosure, letting you switch between Single, RAID 0, RAID 1, RAID 5, and RAID 10 without software. This built‑in hardware RAID manages data distribution and redundancy at the device level, offering faster and more reliable performance than software‑based RAID solutions on a computer.

2. RAID Hot Spare Function

In RAID 1, RAID 5 or RAID 10 configurations, you can assign one drive as a “hot spare.” If an active drive fails, the hot spare automatically takes its place in the RAID array, reducing downtime and protecting your data by rebuilding the array immediately without manual intervention.

3. High‑Speed USB 3.1 Gen 1 Interface

The unit uses a USB‑C port with USB 3.1 Gen 1 support (up to 5 Gbps theoretical throughput). This lets you transfer large files quickly — typical real‑world speeds are around 220 MB/s, which significantly speeds up data copying and reduces workflow wait times.

4. Massive Expandable Storage (Up to 120 TB)

The enclosure can hold up to five SATA drives (3.5″ HDDs or 2.5″ SSDs). Each bay supports large drives — officially up to 24 TB each — giving you a potential total of up to ~120 TB for backups, media libraries, or large datasets.

5. Broad Operating System Compatibility

The D5‑310 works seamlessly with Windows, macOS, and Linux without needing additional drivers, making it plug‑and‑play across multiple systems and devices. This flexibility lets you use it with desktops, laptops, servers, TVs, and set‑top boxes.

 6. Free Windows Backup Software

TerraMaster includes TPC Backupper — a free Windows utility that supports scheduled, incremental, and differential backups. This makes it easy to automate regular backups from your PC to the enclosure, protecting important files and simplifying backup workflows.

7. Tool‑Free Drive Bays with Push‑Lock Mechanism

Installing or swapping drives is quick and tool‑free thanks to the push‑lock trays. You just slide a drive in, and it locks securely — no screws or tools required — saving time and reducing hassle when upgrading or maintaining your storage array.

8. Smart Power & Cooling Features

The D5‑310 includes intelligent drive sleep mode (spins down disks when idle to reduce wear), temperature‑controlled cooling fan (adjusts speed based on real heat), and power‑on recovery (automatically restarts after unexpected power loss). These ensure efficient operation, quieter performance, and better drive longevity.

9. Strong Interface Compatibility

Even though it has a USB‑C port, the enclosure works with USB‑A, USB‑C, USB 3.0/3.1/3.2, Thunderbolt 3/4 hosts using the included USB‑A to USB‑C cable, giving you flexibility with different machines
