Allows up to 128 primary partitions. (MBR disks can support up to four primary partitions and an infinite number of partitions inside an extended partition.)

Allows a much larger volume size - greater than 2 TB, which is the limit for MBR disks.

Provides greater reliability due to replication and cyclical redundancy check (CRC) protection of the partition table.

Can be used as a storage volume on all x64-based platforms.
