    In practical terms for users? You get to use disks larger than 2TB.

    The only difference really is that GPT initialized disks can have partitions of more than 2TB but MBR initialized disks have a limit of 2TB not more. Now to me as a laptop owner, I couldn't care less about that because there are no SSDs of more than 1 TB or HDDs more than 2TB but the reason I always initialize all my disks as GPT is because performance wise, it takes 0.5 seconds less to boot up from a GPT disk as it takes less time for initialization during startup. This off-course is on a UEFI boot not Legacy. To me, every second counts.

    There are many advantages that GPT disks have:
    It can make use of a very large size to break the 2TB limit of MBR disks.
    GPT disks allow an almost unlimited number of partitions. Though Windows implementation restricts the number to 128, it is completely sufficient for using.
    Each GPT partition has a unique identification GUID and a partition content type. And you can have more primary partitions.
    There nearly isn’t any limitation to the size of partition. The sector is numbered by a 64-bit integer. A partition with such number of sectors, can it be small?
    Partition on GPT disk has self-contained backup which is stored on the end of the disk while the original one is saved on the start. When one of the two is destroyed, you can restore it with the other.
    Every partition on GPT disk can has a name which is different from partition label. more information
    Basic disk:A kind of physical disk which can be visited by MS-DOS (Microsoft Disk Operating System) and all Windows-based operating systems. It can contain up to 4 primary partitions or 3 primary partition and 1 extended partition which contains several logical partitions.
    Dynamic disk:It is also a kind of disk whose function is similar to that of the primary partition on basic disk. However, it can split or share data between or among disks. For example, a dynamic disk actually can consist of the storage space which is separated on two single disks. Besides, dynamic disk can copy data between or among disks in case of certain disk damage. This function needs more disks, but it is more reliable.
