What is BCH ECC error correction?

BCH ECC, or Bose–Chaudhuri–Hocquenghem Error Correction Code, is an advanced technology built into many modern flash memory devices to help detect and correct data errors that can naturally occur over time. Because flash memory stores information electronically, small errors can occasionally develop due to normal wear, environmental conditions or repeated use. BCH ECC works automatically in the background to identify and correct these errors before they affect your stored data.

Every TrailBit™ microSD™ card incorporates BCH ECC technology as part of its flash memory management system. While this process is invisible to the user, it plays an important role in maintaining dependable long-term recording performance and supporting the integrity of your files across compatible devices. It's one of several technologies working behind the scenes to help protect your valuable photos, videos and recordings.
