actually, the design of HMS Dreadnought was/is the least effective design for the style of combat for which it was envisioned. All of the battleships whose pictures were shown were designed with broadside battle in mind (aka take two roughly parallel courses and duke it out). Best case scenario is capping the enemy battle-line's T (aka your broadside is exposed to them, while their bows are exposed to you). With HMS Dreadnought's design, regardless of which broadside the enemy is approaching, you will always have 1 turret inactive. In an unrelated note (as seakeeping isnt a huge issue in space), Dreadnought's design was very wet because of its low freeboard and lack of a clipper bow (the pictures of North Carolina and Bismarck have a upward curving bow, this is called a clipper bow, and helps keep the ship design dry). Another reason why it is inefficent is that the armor of Dreadnought had to be spread out to guard all the individual turret loading ports (the big essentially empty cylinders under the turrets from which the shells are loaded), instead of being consolidated in stacked turrets like the Bismarck's armor was.
As for a space battleship, honestly, i would have to say that the best design (from an armor efficency and ammo storage/accessibility/protection standpoint) would be a turret layout more akin to North Carolina's, aka stacked triple mounts on both top and bottom, with a single triple mount on either side, and MAYBE one on both top and bottom aft. Without the necessity to incorporate a clipper bow into the design, that allows 18 guns to fire forwards, with a broadside of (if the aft turrets are included) 18 as well. As Almael said, efficency isn't always about the guns, but with the correct turret and armor layout, you could feasibly pack a relatively large amount of variable angle firepower into a centralized and easily armored warship.
Although i know very little about sci-fi or spaceship design, the arrangement of 2 fore and 1 aft triple turret became the standard layout of WW2 era "superbattleships" (Yamato, Musashi, and the Iowa class), and i dont see why this would change in space
