16GB vs 32GB Speed - Samsung Galaxy Tab S 10.5

So I was going to buy the Samsung Galaxy Tab S 10.5 in the 16GB version. It is expandable up to an additional 128GB through MicroSD so I'm not too worried about space. My question though is will this tablet perform slower as it fills up with Apps and the Android OS? I will save all pictures and videos in the SD card, but didn't know if the native apps and OS will bog down the small hard drive and cause lag... So in summation my question is: Will the 16GB version of the tablet work slower than the 32GB due to space?
