TerraMaster D8 Hybrid 2 8-Bay DAS Enclosure

TerraMaster D8 Hybrid 2 DAS Enclosure, 8 Bays

The TerraMaster D8 Hybrid 2 is an eight-bay DAS enclosure that expands storage capacity to up to 152 TB of raw storage. It supports four SATA 2.5-inch or 3.5-inch HDDs or SSDs and four M.2 2280 NVMe SSDs, combining the capacity of traditional drives with the performance of solid-state storage. Its USB 3.2 Gen 2 Type-C interface provides bandwidth of up to 10 Gb/s, with maximum read speeds of up to 1,020 MB/s. The enclosure is compatible with Windows, macOS and Linux, and can expand storage on compatible NAS servers. TerraMaster TPM power management, intelligent cooling with a quiet FDB fan and tool-free drive installation support convenient use and stable operation.

Eight bays and up to 152 TB of storage

The D8 Hybrid 2 has four SATA drive bays and four slots for 2280-format M.2 NVMe SSDs. Maximum raw capacity is 152 TB when fitted with four 30 TB HDDs and four 8 TB M.2 SSDs. This capacity is suitable for extensive photo libraries, high-resolution video, surveillance footage, graphic design projects and backups.

Combine HDD capacity with SSD speed

The hybrid design lets you use both drive types. Fast M.2 NVMe SSDs can store frequently accessed files, such as active projects, video-editing materials and large working documents. High-capacity HDDs are suited to archival recordings, older projects and backups. This arrangement provides fast access to current data while keeping long-term storage costs lower for large file collections.

USB-C data transfer at up to 10 Gb/s

The USB 3.2 Gen 2 Type-C interface supports data transfer rates of up to 10 Gb/s. Read speeds from a single M.2 SSD can reach 1,020 MB/s, with write speeds of up to 980 MB/s. This performance is useful for transferring large multimedia libraries, exporting video projects and creating backups. A 0.8 m USB-C to USB-C cable is included for connecting the enclosure to a computer.

TerraMaster TPM smart power management

TerraMaster TPM technology adjusts power consumption and drive wake-up behaviour to suit how the enclosure is used. In Power Save mode, the device and drives enter deep sleep, reducing power consumption by up to 98%. This mode is suited to storage that is accessed occasionally. Active Mode keeps selected system components on standby for faster drive wake-up. It reduces power consumption by up to 70% while increasing HDD wake-up speed by 200% and SSD wake-up speed by 600%. Choose between maximum energy savings and shorter waits for file access.

Tool-free installation and drive replacement

The Push-lock mounting system allows HDDs and M.2 SSDs to be installed without additional tools. Its latch mechanism secures drives and helps prevent accidental ejection. This simplifies initial setup and later storage expansion, particularly for users who regularly replace drives. The front-panel power button and drive activity indicators make operation straightforward.

Quiet, efficient cooling

A 120 × 120 × 25 mm FDB (Fluid Dynamic Bearing) fan with intelligent speed control maintains drive temperatures. Fan speed adjusts automatically according to drive temperature to dissipate heat without excessive noise. The noise level is 21 dB(A), and the fan has a rated lifespan of more than 50,000 hours. An optimised internal design improves airflow and reduces vibration for stable operation under heavy loads.

Windows, macOS and Linux compatibility

The enclosure supports Plug and Play operation and does not require additional drivers on supported operating systems. It can connect to Windows, macOS and Linux computers, as well as compatible servers, TVs and other devices that support external USB drives. Supported file systems include NTFS, APFS, EXT4, FAT32 and exFAT. Using exFAT makes it easier to transfer large files between Windows and macOS computers without reformatting the drive each time. Actual read and write capabilities depend on the file system and the connected device.

NAS storage expansion

The D8 Hybrid 2 can serve as an external storage expansion module for NAS servers. It works with compatible TerraMaster servers running TOS 5 or TOS 6 and supports four SATA drives and four M.2 SSDs. Depending on the server and operating system, users can create disk pools, configure RAID arrays and use snapshot features. The enclosure itself operates in Single Disk mode and does not provide hardware RAID. It can also expand storage in environments such as Windows Server, Linux, Proxmox, TrueNAS and Unraid, making it suitable for home storage systems, businesses and creative studios.

Backup support

The D8 Hybrid 2 can store backups of documents, photos, videos and other important files. Windows users can use TerraMaster TPC Backupper, which supports incremental and differential backups. These methods save file changes without copying the entire contents each time, helping to save time and disk space. Mac users can use the built-in Time Machine feature.

Compact design and practical connections

Despite accommodating eight drives, the enclosure measures 222 × 179 × 154 mm and weighs approximately 1.9 kg without drives. It has a USB-C port and a 12 V DC power input. The package includes a 90 W power adapter, power cable, 0.8 m USB-C to USB-C 10 Gb/s cable and documentation.
