Why Use an External Hard Drive for PC Backups?

In an era where our digital lives, from irreplaceable family photos to critical work documents, reside on our computers, a hardware failure or a ransomware attack can be devastating.

To ensure complete peace of mind, establishing a reliable external hard drive backup strategy is no longer just an option; it is a necessity. Performing a hard drive backup for PC using physical hardware remains the "gold standard" for several key reasons:

  • Speed: Transferring large amounts of data is significantly faster via USB 3.0 or USB-C than over Wi-Fi.
  • Cost: You pay once for the drive, avoiding monthly subscription fees.
  • Security: Offline storage (cold storage) keeps your data safe from hackers when the drive is unplugged.

Whether you are looking for a manual solution or the best auto backup software for external hard drive use, this guide covers everything you need to know.
