A drive's write endurance rating is derived at least in part from the JEDEC standard data retention requirements: 1 year at 30C for consumer drives, 3 months at 40C for enterprise drives, IIRC. Thus, a drive that has reached the end of its rated write endurance can be expected to have those retention characteristics. A drive that hasn't been subjected to that much wear will have significantly longer retention.
