Importent features

Importent note: Wear-leveling and ECC error correction and detection is not part of the SD card specification (version 2.0 SDHC), so please check for yourself that the SD(HC)-card support and use:

  • built-in ECC error correction and detection
  • Wear Leveling technology

If the manufacturer advertises the card with e.g. 1,000,000 hours MTBF, it might be a strong indication that the above features are used.

Other importent specifications are:

  • Low power consumption
  • Number of insertions the card endures - 10,000 seems to be good quality.
  • Total I/O operations per second
