SD card suitable for logging?


Many things can go wrong in my BeagleBoard controlled device. I have to log a good amount of text in rolling files (over 20 kB/s). I know it’s nothing close to what a data acquisition system could generate, but I’m still concerned with SD card durability in 24/7 use case. I believe that, for having easily killed many with write intensive activities, pendrives would not be a very good solution either. Well, what are you guys using for logging? And what about durability? I’m starting to consider network solutions or external hard drives, but they add constraints/dependencies to the device.

Looking forward to good advice,
