IN my message i said read or write so reads must be counted. But new  devices 
have unlimited endurance.
 
FM3104...FM31256 are nonvolatiles, unlimited endurance, but have an RTC so  
they need a power, but only for RTC and event counters. they have an I2C  
interface up to 1 mhz so they seems to be fast enough for this data logging  
purpose.
 
These chips are called Integrated Processor Companion with Memory, they  
include Watchdog, Low voltage Reset  Early Powerfail Warning, Serial  Number, 
RTC,... AND all in 14PIN SOIC package.
 
some other simple memory chips with unlimited endurance are available from  
RAMTRON.
 
About data logging, sometime, measurment can be well compressed for  storage, 
leading to a more limited storage bandwith.
 
I2C protocol is not secured, but writes are made byte by byte, as soon as a  
byte is completed, and in the case of a page transaction, it can assure of a  
full secured page write.
