Overview
G-Technology built the G-DRIVE mobile as stylish portable storage for laptop users, with a bus-powered design that needs no wall adapter. It offers Thunderbolt and USB interfaces on a mechanical hard disk.
Choose it for fast backups of documents, music and video on a Mac laptop without carrying a power brick. It relies on a spinning disk, and PC use is never described.
Who it's for
A laptop that backs up with Time Machine and has a Thunderbolt port suits the high-speed link and the missing power brick. Windows users and those wanting shock-proof flash storage should look at other drives.
Pros and cons
- Thunderbolt and USB connections
- Bus powered, no AC adapter
- Time Machine compatible
- Both cables included
- Mac platform listed, PC not described
- Mechanical disk, not flash storage
- Thunderbolt needs a matching port
- Care instructions not listed
Performance notes
The spinning disk sets the sustained speed, and Thunderbolt or USB only decide how much of it the link can carry. Bus power comes through the cable from the laptop, so the drive works without a wall adapter but draws on the battery. Time Machine can back up to it with no setup beyond choosing the drive.
