That's only partly true, fragmentation can and does massively effect SSD performance both on read and write, can effect write latency, but not read latency.
(think of it in terms of an SSD being a huge pile of 4MB blocks where each block needs to be completely erased to clear out old content to get a clearer picture)
- degski 7y agoFrom what I understand, the blocks are just "marked" as being deleted, the TRIM command erases/wipes the content. Windows does this [TRIM], in default setup, once a month.
