I was being a little sarcastic, but damn...30k for data logging? Iguess SD cards require a lot of computing power 
Edit: Ok just checked, my new working code (with florinc's help) totals 222KB for all files combined in the sketch folder. When compiled and uploaded, the status window says
Binary sketch size: 8492 bytes (of a 32256 byte maximum)
so as you can see, compiled code is much smaller.
