Manufacturer description
The G-Technology G-DRIVE mobile USB-C is a 2TB portable external hard drive built for Mac users who move large media libraries between machines. Western Digital rates it at transfer rates up to 140MB/s based on read speed, so offloading a shoot's worth of 4K footage or a photo catalog doesn't stall your workflow. The plug-and-play USB-C port connects without adapters on modern MacBooks, and the drive stays compatible with USB 3.0 and Thunderbolt 3 ports, so an older machine in the studio isn't left out. The stylish aluminum enclosure in Space Gray is deliberately matched to Apple's…

Frequently Asked Questions
How fast is the G-DRIVE mobile USB-C?
Western Digital rates it at transfer rates up to 140MB/s, measured on read speed. Actual throughput varies with your hardware, software, and port.
Does it work with a MacBook Pro without an adapter?
Yes. It has a plug-and-play USB-C port, so it connects directly to USB-C MacBooks. It is also compatible with USB 3.0 and Thunderbolt 3 connections.
Is this an SSD or a hard drive?
It is a mechanical portable hard drive, not an SSD. That is why 2TB lands at this price point, and why speeds cap around 140MB/s rather than SSD territory.
How much can I actually store on the 2TB model?
Western Digital counts one terabyte as one trillion bytes, so formatted capacity shown by your OS will be lower than 2TB. The line goes up to 4TB if you need more.
Can I use it with a Windows PC?
The drive is designed to complement Mac computers and ships Mac-ready, so Windows users should expect to reformat. Check the product listing for current format and warranty details.
