You can't do better than read this comprehensive article. It deals with architecture and the reasons SSD performance degrades over time.

Essentially:

Based on my explanation (read the article) there’s one sure-fire way to make your drive fast again. Formatting/deleting everything on the drive won’t work because those pages on the drive will remain full of data.

If you are doing a clean setup of your machine and want to restore your drive to its native state you’ll have to perform a secure erase. Intel distributed a tool with the first X25-M review kits called HDD ERASE. This tool will take any SSD and free every last page on the drive. Obviously you’ll lose all of your data but your drive will be super fast again!
