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.
