WESTERN DIGITAL SanDisk - SSD PRO-G40 - 4TB - Thunderbolt 3 / USB 3.2 Gen 2

The SanDisk Professional PRO-G40 SSD is an ultra-rugged external solid-state drive offering high-performance storage for demanding workflows. Compatible with Thunderbolt 3 and USB-C, the drive supports collaboration across devices and sustained high transfer speeds for tasks such as high-resolution editing, rendering, and fast file transfer.

Advantages

The PRO-G40 delivers very fast read and write speeds via Thunderbolt 3 and USB-C while maintaining a compact, impact-resistant metal enclosure. It features dual-mode compatibility for broad device support, an internal aluminum cooling core to sustain performance under load, and robust IP68 dust and water resistance along with drop and crush protection for reliable use in challenging environments.

How to use

Connect the PRO-G40 SSD to a compatible host via the Thunderbolt 3 or USB-C port. For maximum performance, use a Thunderbolt 3 connection to achieve speeds up to 3000 MB/s read and 2500 MB/s write; USB-C provides sustained performance up to the specified USB-C speeds. The drive can be used as primary external storage, a scratch disk for high-resolution editing, or a fast-transfer drive for collaborative projects. Ensure the host device meets interface requirements (Thunderbolt 3 or USB-C) and follow the operating system prompts to format or mount the drive as needed.

Recommendations

To maintain performance and longevity, use quality cables rated for Thunderbolt 3 or USB-C, avoid exposing the drive to extreme temperatures for prolonged periods, and periodically back up critical data. For the best sustained throughput during heavy editing or rendering tasks, connect via Thunderbolt 3 and allow airflow around the device to assist the internal cooling core.
