Is MBR or GPT better?

GPT is better than MBR if your hard disk is larger than 2TB. Since you can only use 2TB of space from a 512B sector hard disk if you initialize it to MBR, you’d better format your disk to GPT if it is larger than 2TB. But if the disk is employing 4K native sector, you can use 16TB space.
