    High-Speed Transmission

    D5-310 uses the USB 3.1 Gen 1 high-speed transmission protocol, with a theoretical transfer speed of up to 5Gbps and an actual read/write speed of up to 220MB/s. Transferring a 1GB file takes only about 4 seconds, significantly reducing waiting time during office tasks and greatly enhancing work efficiency.

    High-Speed Transmission
    120TB Storage

    The D5-310 boasts powerful storage expansion capabilities, supporting the installation of up to 5 hard drives with a maximum individual hard drive capacity of an astonishing 24 TB (Compatibility with larger capacity hard drives is yet to be verified). This means that users can achieve massive storage of up to 120 TB (24 TB x 5), allowing the D5-310 to meet a wide variety of large-scale storage needs.

    120TB Storage
    Compatible with Various Hard Drives

    The D5-310 supports multiple types of hard drives, including 3.5-inch SATA hard drives, 2.5-inch SATA hard drives, and 2.5-inch SATA SSDs.

    To ensure the stable operation and optimal performance of the device, it is crucial to select hard drives that are known to be compatible. Incompatible hard drives may result in device disconnection, reduced speeds, or failure to recognize a hard drive. Before making any drive purchases, users are thus strongly advised to refer to TerraMaster's hard drive compatibility list to ensure that the chosen hard drives are a perfect match for the D5-310 to ensure a seamless storage experience.

    Compatible with Various Hard Drives
    Supports RAID Hot Spare Disk

    When configured in RAID 1, RAID 5, or RAID 10 mode, the product allows for the addition of a hot spare disk. This feature ensures that in the event of a single disk failure within the RAID array, the hot spare can immediately replace the failed disk, effectively minimizing the risk of data loss and providing robust protection for your data security.

    Supports RAID Hot Spare Disk
    Strong Interface Compatibility

    The D5-310 features a USB Type-C interface and comes with a 0.8-meter USB Type-A to Type-C cable. This design allows the D5-310 to seamlessly connect to various computer interfaces, including USB 3.0, USB 3.1, USB 3.2, USB 4,Thunderbolt 3, and Thunderbolt 4. Regardless of the type of interface the computer uses, the D5-310 can thus provide a stable and efficient data transfer experience.

    Easier Hard Disk Replacement
    Supports RAID Hot Spare Disk

    When configured in RAID 1, RAID 5, or RAID 10 mode, the product allows for the addition of a hot spare disk. This feature ensures that in the event of a single disk failure within the RAID array, the hot spare can immediately replace the failed disk, effectively minimizing the risk of data loss and providing robust protection for your data security.

    Supports RAID Hot Spare Disk
    Risk Warning Alert

    When a RAID array experiences a missing disk or failure, the system activates an audible "beep-beep" alarm through the built-in buzzer. This indicates that the RAID array is in an incomplete state and requires immediate action to repair it, ensuring data integrity and system stability.

    Risk Warning Alert
    Intelligent Hard Drive Sleep

    D5-310 features a hard drive sleep function. When the device is safely disconnected from the computer, the computer enters sleep or shutdown mode, or the USB cable is unplugged, the hard drive automatically enters sleep mode, and the fan stops spinning. This design not only reduces the hard drive's operating time and minimizes wear on its motor but also significantly extends its lifespan. It allows you to enjoy efficient storage while confidently protecting your hard drive investment.

    Intelligent Hard Drive Sleep
    Power-On Recovery Function

    This product features a power-on recovery memory function, intelligently handling various power loss scenarios. When the D5-310 is shut down properly, it remains off when power is restored. However, if the device shuts down due to an abnormal power outage, it will automatically power on when electricity is restored. This feature makes the D5-310 an excellent choice for integration with servers, NAS devices, and other systems, enabling automated and unattended management.

    Power-On Recovery Function
    Smart Temperature-Controlled Fan

    D5-310 equipped with an innovative MCU_PWM smart temperature-controlled fan system, which dynamically adjusts the fan speed based on the real-time temperature of the hard drives. This design surpasses the traditional fixed-speed fan systems commonly used in conventional drive enclosures, effectively preventing unnecessary high fan speeds when the hard drive temperature is low. This results in more efficient and energy-saving heat management.

    Smart Temperature-Controlled Fan
    Safety

    To ensure the safety of the device and hard drives, the D5-310 incorporates an advanced power protection design. In the event of users incorrectly connecting an incompatible power source, the device will immediately activate a built-in protection mechanism, effectively preventing damage to the device and hard drives from excessive currents or unstable voltages. This considerate design offers added peace of mind on using the D5-310, eliminating any concerns about potential losses due to power-related issues.
