Look for keywords like “Mac-compatible” or “Time Machine compatible” to ensure the drive is optimized for use with your Mac. You can also check the product description or manufacturer’s website for any specific compatibility notes.

What’s the difference between a USB and Thunderbolt external hard drive?

The main difference between a USB and Thunderbolt external hard drive lies in their connectivity and speed. USB (Universal Serial Bus) is a common connectivity standard used for peripherals like external hard drives, keyboards, and mice. USB 3.0, the latest version, offers speeds of up to 5 Gbps (gigabits per second). On the other hand, Thunderbolt is a high-speed connectivity standard developed by Intel and Apple, offering speeds of up to 10 Gbps.

When choosing between a USB and Thunderbolt external hard drive, consider your needs and the speed of your data transfer. If you’re dealing with large files or need fast data transfer, a Thunderbolt drive may be the better choice.
