WebOct 18, 2024 · If the flash drive only implements dynamic wear leveling, then if I write to all of the blocks, in order, and don't re-use any of them, then there are no free blocks to perform dynamic wear leveling with. Without TRIM, to tell the flash drive that those blocks really aren't in use - well, I don't see how it can wear-level at that point. WebAug 6, 2024 · Dynamic wear leveling only handles free space and ensures that write behavior will only occur in blocks that have a lower erase count in the same space. Static wear leveling considers the entire Flash die, including blank areas and blocks to which have been written.

WebNov 20, 2024 · This process is known as wear-leveling. Traditionally, there have been two types of wear-leveling: static and dynamic. Dynamic wear-leveling will pick blocks with the lowest erase count from among free blocks when it’s time to do a new write. On the flip side, static wear-leveling will consider all blocks in its analysis. WebApr 10, 2024 · Dynamic wear leveling is a more advanced approach that considers the usage patterns of the SSD to distribute write operations. With dynamic wear leveling, the SSD controller constantly monitors the usage patterns of the NAND memory and dynamically allocates blocks based on their usage. This means that frequently used …
