The difference between MBR and GPT partitioning!

MBR (Master Boot Record)

1. Master boot record, traditional partitioning mechanism, applied to most PC devices using BIOS

2. MBR supports 32-bit and 64-bit systems.

3, MBR supports a limited number of partitions.

4, MBR only support less than 2T of hard disk, more than 2T of hard disk will only use 2T space (there is a third-party solution).

5, MBR is often used for personal PC disk partition.

GPT (GUID Partition Table)

1, the Globally unique identity partition table, is a relatively new partition mechanism, solves many shortcomings of the MBR.

2, support more than 2T of disk (64-bit addressing space). In Linux , Fdisk can only create partitions of 2TB size, creating a partition larger than 2TB using parted.

3, backward compatible with MBR.

4. It must be used on UEFI-enabled hardware (Intel proposes to replace the BIOS).

5.64-bit system must be used.

6, MAC, Linux system can support GPT partition format.

7, Windows 7/8 64bit, Windows Server 64bit support GPT, but not commonly used.

Personal Summary: Generally speaking, GPT is more advanced than MBR, accustomed to server large capacity, but MBR compatibility is better than GPT, MBR is more suitable for office long disk. Maybe it has something to do with long-term habits!
