PurrfectBackup USB Copy Speed Is Slow

If your USB copy speed seems slower than expected, even with a fast SD card, CFexpress, or SSD, the issue is usually related to the USB cable or device compatibility.

Recommended Solution

  • Use certified 10Gbps USB cables that are included with your PurrfectBackup device.
  • Avoid using cheap or uncertified third-party cables that only support USB 2.0 or 400mbps.
  • Make sure your SSD or card reader supports minimum USB 3.1 Gen 2 (10Gbps) speeds.
  • Connect drives directly to PurrfectBackup, not through hubs or splitters.

Tip: Using high-quality cables ensures maximum performance for photo and video backups, especially for RAW and 4K files.
