TERRAMASTER D9-320 Hard Drive Enclosure - 9Bay USB 3.2 Gen2 10Gbps Type-C External HDD Storage Independent Power Control for Each Bay Hot Swappable Plug and Play (Diskless)

- 9 Independent Power Supply for 9 Drives: This D9-320 9-bay hard drive enclosure (a DAS, NOT a NAS) is equipped with 9 independent drive power switches and a master power switch, allowing users to individually power down unused drives. This feature effectively saves energy and significantly extends the lifespan of the hard drives. Its intelligent shutdown system safely parks heads to prevent data loss and avoid SMART errors from sudden power loss. - Super-large Storage Space: The D9-320 HDD storage enclosure can support up to 9 x 3.5" and 2.5" SATA HDD, as well as 2.5" SATA SSD, with a maximum capacity of 30TB per drive, providing users with up to 270TB (30TB x 9) of storage space. Note that the D9-320 does not support arrays and only works with individual disks. - High Speed: The D9-320 hard drive enclosure adopts USB 3.2 Gen2 protocol for high-speed data transmission up to 10Gbps. With 9 hard drives installed, the read/write speed can reach up to 1,030MB/s (SATA III HDD 8TB x 9). With one SSD installed, the read speed can reach 510MB/s (SATA III 1TB SSD x 1). - Plug and Play, Highly Compatible: The D9-320 DAS storage is a plug-and-play device that doesn't require drivers to work. It is highly compatible with MAC, Windows, and Linux operating systems. It has a USB Type-C interface and comes with two USB cables (1 x USB type C-C cable, 1 x USB type A-C cable). The device is compatible with various computer interfaces, including USB 4.0, USB 3.2, USB 3.1, USB 3.0, Thunderbolt 5 , Thunderbolt 4, and Thunderbolt 3. - Better Heat Dissipation: The D9-320 USB storage has an intelligent temperature-controlled and 3 low-noise fans that automatically adjusts its speed based on the temperature of the hard disk. This feature ensures that the hard disk operates at its best temperature and provides better heat dissipation. The D9-320 USB enclosure supports hot swapping, which allows you to replace the hard disk without having to power off the device. This feature makes data transfer more convenient and efficient.

Per-Drive Power Control ? Smart & Energy-Efficient HDD Enclosure: The D9-320 hard drive enclosure features 9 independent power switches, allowing you to turn off unused drives individually. This direct attached storage (DAS) innovation reduces power consumption, minimizes wear, and extends HDD lifespan - perfect for long-term storage and cold data archiving.

Massive 270TB Storage - Ultimate Capacity for Demanding Workloads: Supporting 9 drives (30TB each), this USB storage beast delivers 270TB raw space - ideal for 8K video editing, enterprise backups, and large-scale data expansion. The HDD enclosure operates in single-disk mode (individual disks) by default, ensuring direct access to each drive without RAID restrictions.

10Gbps High-Speed USB Storage - Blazing Multi-Drive Performance: With USB 3.2 Gen2 (10Gbps), the D9-320 external USB enclosure solution hits 1016MB/s with 9 HDDs and 510MB/s with a single SSD - perfect for fast media workflows, virtualization, and server expansions.

Daisy-Chain Expansion - Scalable 9-bay DAS Enclosure for Workstations: The built-in USB Host port lets you connect multiple D9-320 units in series, solving limited PC ports. The D9-320 is ideal for studios and IT teams needing flexible USB storage expansion.

Universal Compatibility - Works as External Storage for Any System: Supports Windows, macOS, Linux, and NAS OS (TOS/TrueNAS/Unraid/Proxmox). The USB-C & Thunderbolt compatibility ensures seamless connections, while the all-metal chassis ensures 24/7 reliability for heavy workloads.

Note: Some mini PCs may have weaker USB signal output, which can cause random interruptions during file read/write operations during data transmission. When this occurs, it is recommended to 1) use the rear USB ports of the computer, as they typically provide a more stable signal; 2) test the device on another known-good computer to rule out hardware issues on the original PC; and 3) use a 10Gbps USB-A/USB-C hub or splitter with a short 0.3m?0.5m cable to reduce signal loss.
