Frequently Asked Questions
Is the PRO-G40 SSD compatible with Windows?
While the PRO-G40 is pre-formatted in APFS for optimal macOS performance, it can be reformatted to exFAT or NTFS for Windows compatibility. However, for best results and native performance, it's recommended for Mac-based workflows.
What makes this Thunderbolt 3 SSD ideal for video editing?
The PRO-G40's exceptional 3000 MB/s read and 2500 MB/s write speeds eliminate bottlenecks when working with 4K and 8K video files. Combined with APFS optimization, it provides the sustained performance required for real-time editing and rendering tasks.
How durable is the IP68-rated external SSD?
The IP68 rating means the PRO-G40 is fully protected against dust ingress and can withstand submersion in water up to 1.5 meters for 30 minutes. Add the 3-meter drop resistance, and you have professional-grade protection for demanding field work.
Can I use the PRO-G40 with older Mac computers?
The Thunderbolt 3 connection requires a compatible Mac with Thunderbolt 3 ports (2016 or newer models). Alternatively, you can use the USB 3.2 Gen 2 connection with any Mac featuring USB-C, though speeds will be lower than Thunderbolt 3.
