Why Do I Get a Message Saying My SD Card is Too Slow?


  • Motorola Phones
  • Android Version 6.0 or higher


When you insert an SD card into your phone, you can choose to use the card as Portable Storage or Internal Storage. If you choose Internal Storage, you may experience the following error message:

"This SD card appears to be slow. You can continue, but apps moved to this location may stutter and data transfers may take a long time. Consider using a faster SD card for better performance."

This message indicates that your SD card is too slow to use for Internal Storage. Motorola recommends the use of a high speed SD card (UHS-1) for expanding the phone's Internal Storage.
