Tiny SD Shield - standard library overhead

I am contemplating adding SD support to a "Tiny" project that is now using
Nordic BLE, 9-axis IMU and USB.  I've not yet completed the logic code
that I need, and I see that I've got about 5KB of program space remaining!
Does anyone know how much of that would be eaten up by the SD support?
I may have to re-architect, but hope to avoid that!
Thanks!

The SD TinyShield and Nordic BLE TinyShield have a pin conflict- pin 10 is the chip select for both boards. As well, the SD code library adds something in the are of 10KB when in typical use. Maybe there's another solution like our EEPROM or upcoming flash memory board, depending on your use case.
