For me writing by hand helps for remembering a very specific type of knowledge. If I need to remember random facts with not much cohesion between them, it helps to write them down. I feel I create a visual memory of these facts. Almost like "oh yes, I remember writing that down near the left bottom of the page". But for any type of knowledge that's more about understanding than pure remembering, I learn better without writing by hand.
