WebB-trees node has more branching factor meaning the node has more than 2 child nodes which in turn makes the height small. When a tree has a small height, it takes less number of read operations to go from root to any leaf node. A binary search tree (AVL or Red-Black) is much deeper than a B-tree with the same number of keys.
