Extra Slot for SSD

Hi, I was just wondering if there is an extra slot for SSD. I just discovered that it is twice faster than a regular HDD but what I mean with the extra slot, is literally extra slot like I don't have to remove the HDD to replace it with SSD. Can I have them both? The reason my laptop has 1TB HDD which is way too much storage than a 120gb SSD which only I can afford. I just need a yes or no, so I know if I am going to save money for it or nah. Btw, my laptop model is Inspiron 15 7567 Gaming. Thanks in advance!!
