Smartctl always prints the (normalized) attribute VALUE as reported by 
the drive. I don't know why the firmware author decided to report 100% 
even after extensive use :-)

You may want to ask the question in Intel forums:
https://communities.intel.com/community/tech/solidstate

Please also check "Percentage Used Endurance Indicator" of "SSD Device 
Statistics":
'smartctl -l ssd', included in '-l devstat', included in '-x'
(requires smartctl >= 5.42)

74285755253828 = 0x4390000dc444

This device uses the power on time format of most SandForce based 
devices: The upper bytes contain a milliseconds counter. Smartctl does 
not print this correctly because the drive database is not up to date:
http://sourceforge.net/apps/trac/smartmontools/wiki/Download#Updatethedrivedatabase

You could also try the '-v 9,msec24hours32' command line option.

But even then smartctl would print 0xdc444 = 902212 power on hours. This 
is a known firmware bug:
