Speeding up writing to a SD card : arduino - reddit

Read in data from sensor, store it in Buffer 1. Once Buffer 1 hits a selected size (e. g. 256 bytes), direct buffering to Buffer 2. Write the data from Buffer 1 to the SD card, clear Buffer 1. Once Buffer 2 hits a selected size (again 256 bytes), repeat the process and direct it back to Buffer 1. From the SDfatlib package, which Arduino uses
