Wouldn't the firmware on the drive typically ensure that it's written to evenly regardless of write pattern? If you repeatedly delete/update the 'same' logical block address on the drive, that won't actually correspond to the same physical location.
You can only cheaply do so with free blocks, and if 70% is occupied you can only spread it out over the remaining 30%. After you've done that for a while you'll have to rearrange existing data which incurs more writes and less performance. And fragmentation is still an issue.
There are tons of tradeoffs - which will be better or worse for different workloads. But to assume that it wear perfectly, which most people seem to do because it is easy, isn't particularly realistic.
Sequential workloads and just filling the drive over and over are very different still.
So if you fill the drive over and over using sequential writes you can expect way more endurance than if you write random blocks.
