Steven,

I'm not sure I understand what you are asking.  I'm using standard SD cards.

RT.

  Do you have a link to the SD you use? Steve

  Hi John,

  About the largest I2C EEPROM's that I am aware of are 1Mbit capacity.

  Is there a reason why you would not want to go the SPI route? Atmel
  has several serial flashes in the 8-128Mbit range. A 16Mbit serial flash
  is less than $2 and offers the advantage of higher access speeds.

  I was in the same situation several months ago and looked at the Atmel
  serial flashes. However, I have decided to go with SD (since I can use
  an SPI interface with them) and 1GB cards today are at $6 or so.

  I need much higher capacity, 1 MB (8 Mbit) minimum, for data logging.

  Why is it required to be flash. There are I2C EEPROM's supporting
  over 1 million write cycles. This for me is more than sufficient. 
  i.e. 24LC256
