TerraMaster Launches 'D1 SSD' Rugged NVMe External Enclosure with IP67 Rating and 1.2-Ton Pressure Resistance

April 28, 2026 | TerraMaster

TerraMaster, a professional storage brand, today announced the 'D1 SSD,' a portable NVMe external SSD enclosure with 'three-proof' (waterproof, dustproof, and pressure-resistant) specifications. This model was developed for users who prioritize data protection and high-speed transfer, featuring three high-durability designs: an aircraft-grade aluminum unibody, IP67 waterproofing and dustproofing, and a 1.2-ton pressure-resistant structure. Furthermore, it boasts high-speed transfer via USB 3.2 Gen2, a fanless silent design, and broad compatibility with Windows, macOS, and Linux, positioning it as a highly reliable mobile storage solution for photography, outdoor work, and mobile tasks.

### Enhanced Data Protection with Triple High-Durability Design

High-Strength Aluminum Unibody The unibody full-metal chassis, made from aircraft-grade aluminum alloy, ensures scratch and corrosion resistance. It maintains stable operation even under harsh environments like long commutes or frequent use, enhancing the durability and long-term reliability of the external SSD.

IP67 Waterproof and Dustproof Compliance Its precision sealing structure complies with the IP67 standard. It has passed immersion tests at a depth of 1 meter for 30 minutes, protecting the internal NVMe SSD and data from rain or dust. It has cleared tests by international third-party inspection agencies like SGS, ensuring high reliability.

1.2-Ton Pressure and Impact Resistance The aircraft-grade aluminum unibody achieves high rigidity and structural strength. With a pressure resistance capable of withstanding a 1.2-ton load, combined with impact and vibration resistance, it protects internal storage from drops and external impacts, reducing the damage risks common in standard SSD cases.

### High-Speed Transfer, Silent Design, and Large Capacity Support

The D1 SSD features a USB 3.2 Gen2 interface and supports the UASP protocol and TRIM commands. It achieves continuous read/write speeds of up to 1020MB/s, enabling the transfer of a 1GB file in seconds. It smoothly handles high-load data processing like 4K video editing and bulk RAW photo backups. The fanless design and full-metal cooling structure ensure zero operation noise, maintaining stable performance during long transfers.

It also supports M.2 2280 NVMe SSDs (PCIe 3.0/4.0/5.0) up to 8TB. At its maximum capacity, it can store approximately 2.79 million high-quality photos or 5,400 high-quality videos. It supports major operating systems like Windows, macOS, and Linux, and features a plug-and-play design compatible with PCs, TVs, and OTG-supported mobile devices.

Moreover, by linking with the dedicated mobile app 'TDAS,' users can automatically sync album data just by connecting a smartphone. It enables one-touch photo backups without tedious manual operations. Since data is saved locally to the device without passing through the cloud, it minimizes exposure risks and ensures privacy. This enables efficient and secure file management across multiple devices.

### Versatile Use Cases for Broad User Needs

● For Photography Enthusiasts and Outdoor Workers Its dustproof, impact-resistant, and vibration-resistant design ensures stable operation in harsh environments like outdoor shoots or construction sites. Important data can be backed up instantly on-site, reducing the risk of loss.

● For Mobile Workers and Students With a lightweight body of about 146g and a pocket-sized design, it offers excellent portability. High-speed file transfer performance creates a comfortable data work environment on the go, ideal for mobile work and online classes.

● For General and Mac Users Beyond capacity expansion, it can be used as an external boot drive. The silent design and plug-and-play support ensure smooth adoption in Windows and macOS environments.
