What’s more, on MBR disks, you are allowed to create only up to 4 primary partitions, while on a GPT disk, you can create up to 128 primary partitions.Īnother thing that goes in the favor of GPT is that it stores multiple copies of data across the disk, making it a more robust solution in terms of data backup. It is also a prerequisite for large disks because while MBR supports disks of only up to two terabytes (2TB) in capacity, GPT can handle a theoretical maximum of up to 18EB (Exabyte). One major advantage of GPT disks is that you can have more than four partitions on each disk. While MBR disks use the standard BIOS partition table, GPT disks use UEFI. The latter is the relatively new technology and is slowly replacing the legacy one because it’s faster, more secured and can natively address larger storage disks.
MBR (Master Boot Record) and GPT (GUID Partition Table) are two different partition styles for hard disks, and both are widely used for disk partition management in Windows computers.
