это все форумная магия. есть два алогоритма, и все их реализуют в FTL, в основном сейчас dynamic, static используют в пром ссд для станков или специальных регистраторов, на некоторых ссд хитачи можно переключать алгоритм специальным софтом

TN-29-61 Wear Leveling in NAND Flash Memory Wear Leveling Algorithms
Wear leveling is associated with a block aging table (BAT) to store information about which blocks have been erased in a selected period of time.
There are two kinds of wear leveling that can be implemented in the FTL:
• Dynamic wear leveling
• Static wear leveling
Dynamic Wear Leveling
When applying the dynamic wear leveling, new data is programmed to the free blocks (among blocks used to store user data) that have had the fewest WRITE/ERASE cycles.
Static Wear Leveling
With static wear leveling, the content of blocks storing static data (such as code) is copied to another block so that the original block can be used for data that is changed more frequently.
Static wear leveling is triggered when the difference between the maximum and the minimum number of WRITE/ERASE cycles per block reaches a specific threshold. With this particular technique, the mean age of physical NAND blocks is maintained constant.
