GPT - what is behind it?

Each hard drive contains at least one partition and the GPT defines the partition table. Accordingly, the three letters GPT stand for Guid Partition Table.

The advantages of the Guid Partition Table (GPT) over the Master Boot Record (MBR)

The master boot record, which contains the partition table, works together with the BIOS and both have gotten a bit long in the meantime. Therefore, they no longer meet the requirements of modern hardware and software - such as hard drives.

• The Guid Partition Table, on the other hand, which is implemented as standard in the successor of the bios, the UEFI, offers you some advantages over the somewhat outdated MBR.
• While a maximum of four primary partitions could be managed with the master boot record, this barrier has been removed from the GPT.
• So far, you could only use about 2 terabytes of hard disk space under MBR. Of course, this is no longer sufficient for today's storage requirements and modern hard drives. With the GPT, on the other hand, you could easily use 18 exabytes of storage space.
• However, the Guid Partition Table is limited to 256 terabytes by the currently used NTFS file system, but this is still good enough for home computers at the present time.
