USB4 NVMe SSD Enclosure for High-Speed Storage

When large video files, backups, and project data take too long to transfer, your external storage can become a serious bottleneck. A USB4 NVMe SSD Enclosure gives you a practical way to turn a compatible M.2 NVMe SSD into high-speed portable storage. The EVUC TUM4 combines USB4 and Thunderbolt 4 connectivity with a theoretical transfer rate of up to 40Gbps. In addition, its fanless aluminum cooling structure helps manage heat during demanding workloads. For professionals working with 4K/8K video, large project files, or frequent backups, support for M.2 2280 NVMe SSDs up to 8TB provides a flexible external storage solution.

Why Choose a USB4 NVMe SSD Enclosure?

The TUM4 is designed for users who need more than basic external storage. Its ASM2464PD chipset supports USB4 and Thunderbolt 4 protocols, providing the bandwidth required for large file transfers and storage-intensive applications.

For example, video editors can use a compatible NVMe SSD to work with large media files, while photographers can move extensive RAW image libraries between workstations. Similarly, businesses can use portable NVMe storage for backups, project transfers, and data archiving.

40Gbps USB4 and Thunderbolt 4 Connectivity

The TUM4 supports a theoretical interface speed of up to 40Gbps. Under the specified test conditions, the enclosure can achieve read speeds of up to 3400MB/s and write speeds of up to 3200MB/s.

Furthermore, the enclosure supports:

• Thunderbolt 4 ports
• Thunderbolt 3 ports
• USB4 ports
• Compatible Windows systems
• Compatible Mac systems

For Windows users, a compatible Thunderbolt 4/3 or USB4 port is required for the intended high-speed functionality. Therefore, you should check your computer's port specifications before purchasing or configuring the enclosure.

Fanless Cooling for Stable Operation

Continuous NVMe data transfers can generate heat, which may affect storage performance. For this reason, the TUM4 uses a fanless cooling design rather than a mechanical cooling fan.

The aluminum alloy shell works together with an aluminum heat sink and silicone thermal pad to transfer heat away from the SSD. As a result, the enclosure provides passive heat dissipation while avoiding mechanical fan noise.

This design is particularly suitable for quiet offices, content creation environments, and portable storage applications where low-noise operation matters.

TUM4 M.2 NVMe SSD Enclosure Specifications

The TUM4 combines high-speed connectivity, NVMe compatibility, and a compact aluminum enclosure.

With these specifications, the TUM4 can support applications that require high bandwidth, portable storage, and effective passive cooling.

How to Use the USB4 NVMe SSD Enclosure

You can configure the TUM4 with a compatible M.2 2280 NVMe SSD by following these basic steps:

1. Select an M.2 2280 NVMe SSD with a capacity of up to 8TB.
2. Install the SSD inside the TUM4 enclosure according to the product installation structure.
3. Position the thermal components correctly so the silicone thermal pad and heat sink can transfer heat effectively.
4. Connect the 265mm Type-C cable to the enclosure and a compatible USB4 or Thunderbolt port.
5. Initialize or format the SSD through your operating system if the drive is new.
6. Transfer your files and use the external NVMe storage for editing, backups, gaming, or other storage-intensive tasks.

Before using the enclosure at high transfer speeds, make sure your host computer, cable, SSD, and operating system support the required interface specifications.
