Go to page 24 "Endurance Rating" and you see the last requirement is:
"4) the SSD retains data with power off for the required time for its application class."
Then go down to page 25 and you will see that the above "required time for its application class" for a "client class" device is 1yr.
This is consistent with many NAND device datasheets that I've been dealing with. It is common to spec 10 years min power off data retention when new and 1 year when they've reached their max write rating.
