Why do you need SSD

SSD are much much faster that HDD because they don’t have moving parts. I will not explain it in detail, you can search internet if you need more details. As result Windows will load way faster. Any software, games will load much faster as well. If you play game that load parts of level dynamically without load screen, then there is much less chance to see micro freezes. If you work in some application and press Save button it will save much faster. In general experience are much better than with traditional HDD. It is really hard to explain until you actually experience it.
