When using external hard drives across both Windows and macOS platforms, it's important to understand the optimal file system formats for each operating system and how to ensure compatibility.

Native File Systems for Each Platform

macOS: Works best with HFS+ or APFS (Apple's native formats)
Windows: Works best with NTFS (Microsoft's native format)

Using a drive with its matching operating system ensures optimal performance and data access.

Cross-Platform Compatibility Options

Using a Windows-formatted drive (NTFS) on macOS or a Mac-formatted drive (HFS+/APFS) on Windows requires third-party plugins like Tuxera NTFS or Paragon NTFS. However, our testing shows these plugins may reduce drive performance and speed.

Recommended Strategies

Option 1: Format Based on Primary Device

If you primarily use macOS: Format with HFS+ or APFS and install compatibility plugins on Windows
If you primarily use Windows: Format with NTFS and install compatibility plugins on macOS

Option 2: Use a Universal Format

We recommend using exFAT format for drives that need to work on both Windows and macOS without additional software.

Important note: Unlike NTFS and some other file systems, exFAT lacks journaling capabilities, which increases the risk of data loss during system crashes or power interruptions. When using exFAT-formatted drives, make sure to back up your data regularly.
