The enclosure is crafted from aluminum, matching the aesthetic of Apple's Mac lineup. It comes pre-formatted in HFS+J, so you can plug it into a Mac and start using it immediately.

Compatibility Guide

The G-DRIVE Mobile connects via USB 3.0 and includes both USB-C and USB-A cables. This means it works with any computer that has a USB port, from the latest MacBook Pro to older Windows laptops. On Mac, it's pre-formatted as HFS+J and works out of the box. For Windows 10/8.1, you'll need to reformat it to NTFS or exFAT. It fully supports Apple Time Machine for effortless backups.

Product Info

The G-DRIVE Mobile USB 3.0 4TB (model 0G06074) is a mid-range portable HDD from Western Digital's G-Technology brand. Its key selling points are the premium aluminum build and deep Mac integration. Key specs include 4TB capacity, USB 3.0 interface, 130MB/s max read speed, dimensions 82×110×10.5mm, weight 138g, and a 3-year warranty. It comes with USB-C and USB-A cables and is bus-powered, so no external power adapter is needed.

Best Use Cases

  • Mac backup drive: Ideal for Time Machine backups thanks to native HFS+J formatting and full Time Machine support. The aluminum design complements Mac hardware. Not ideal for Windows users who would need to reformat.
  • Creative professionals on the go: Photographers and videographers can use the 4TB capacity to carry large media libraries. However, the 130MB/s speed is slower than SSDs, so it's best for archival storage rather than active editing.
  • Secondary storage for laptops: When your laptop's internal SSD runs out of space, this drive provides extra room for documents, music, and less frequently accessed files. Its bus-powered operation means no extra cables or adapters. Be aware that HDDs are more sensitive to physical shock than SSDs.

Things to Consider

As a traditional hard drive, the G-DRIVE Mobile is significantly slower than any SSD. The 130MB/s maximum is fine for backups and file transfers but not suitable for running applications or operating systems. The drive is also vulnerable to drops and impacts, so handle it with care.
If you primarily use Windows, you'll need to reformat the drive, which erases all data. Competing products like WD My Passport or Seagate Backup Plus come pre-formatted for Windows and are often priced similarly. Choose this G-DRIVE if Mac compatibility and design are your priorities; otherwise, a Windows-native drive may be more convenient.

A: Yes, it fully supports Apple Time Machine. Simply select it as the backup disk in System Preferences.
