There isn't really any studies going on as far as know for endurance among reviewers.
The reason is quite simple. Write endurance is a moving goalpost from user to user, and it's governed by the following factors.
The NAND rated write cycles (PE/C).
The capacity of the SSD.
The write amplification of the controller.
The amount of data on the drive, or to be more accurate. The amount of free space on the SSD.
The most important factor is the amount of free space, as the wear levelling algorithms will move around the data to make sure all NAND is worn evenly. The less free space there is on the SSD, then the faster the write cycles are used.
Since all users will have different amounts of free space, you can appreciate how difficult it is to try and test for endurance.
The only thing I would say is. If you have around 20% free space, then you should expect to get at least 15 years of use out of the SSD. By which time it will long past its sell by date.
