  • partitioning scheme that addresses the limitations of the older Master Boot Record system.
  • GPT is integral to the [[OS Boot/UEFI]] standard, replacing the traditional BIOS.
  • GPT can handle drives larger than 2 terabytes supporting sizes up to 9.4 zettabytes due to its use of 64-bit logical block addressing.

[!INFO] [[MBR]] is limited to a maximum of 2TB.

  • GPT allows for a significantly higher number of partitions. While MBR limits users to four primary partitions (or up to 26 if using extended partitions).

[!INFO] GPT support up to 128 partitions without the need for extended or [[logical partitions]].
