Thread: SD or SdFat for Tweensy 3.2

    SD or SdFat for Tweensy 3.2


    I'm building a datalogger where i'll store 80 or so bytes every second. I can go SD or SdFat.

    Does anyone know if either library is better/faster/more reliable/other?

    Thanks in advance

    SD is a more user friendly wrapper around an old version of SdFat. It is slower and less optimized than the current version of SdFat, but considerably easier to start with (although imo the SdFat examples are self-explanatory). For small, non-critical SD transactions you'll be fine with SD. For fast, critical stuff, or when you want to do it right the first time, you better use SdFat.
