How We Picked the Best External Backup Drives for Time Machine and PC
We focused on drives that balance compatibility, capacity, portability, and backup-friendly features. For External Backup Drives for Time Machine and PC, the most important factors are dependable storage, straightforward setup, and software or filesystem support that works with your system.

Quick Comparison
Portable hard drives in this list are best for general backup, larger photo and video libraries, and users who want simple plug-and-play storage. Smaller-capacity devices are more suited to file transfer or media organization, while higher-capacity models are a better fit for complete system backups and long-term archives.
Key Buying Factors for External Backup Drives for Time Machine and PC
Capacity
Match the drive size to your data. A 2TB drive may be enough for lighter backup needs, while 5TB or 6TB makes more sense for multiple computers, large photo libraries, or frequent Time Machine backups. If you plan to store both work files and personal media, go bigger than you think you need.
Compatibility
Mac users should confirm support for Time Machine and consider whether the drive is ready for APFS or requires reformatting. PC users should check whether the drive works out of the box with Windows or needs setup changes. If you want one drive for both platforms, file format planning matters.
Portability and Connection
USB 3.0 and USB 3.1 support help keep transfers practical, especially with large backups. If you travel often or move files between devices, a compact portable drive is usually the better choice than a desktop unit.
Backup Software and Security
Included backup software can simplify scheduling and automation. Password protection and ransomware-focused features are worth considering if your drive stores sensitive business files, family photos, or anything you cannot easily replace.
Who Should Buy Which External Backup Drives for Time Machine and PC?
If you want a straightforward everyday backup drive for a Mac or Windows laptop, a 2TB portable model is a sensible starting point. If you have lots of photos, videos, or multiple devices to protect, 5TB or 6TB gives you more breathing room.
Choose the smaller PhotoStick-style options if your main goal is quick photo and video backup rather than full-device storage. Pick the larger WD or Seagate portable drives if you need more flexible, general-purpose External Backup Drives for Time Machine and PC use.
