What is GPT Partition?
GPT stands for GUID (Globally Unique Identifier) Partition Table. It is a modern partition scheme that offers more versatile functionality compared to MBR partitioning scheme. Following are keypoints on GPT Partitioning scheme :-
- Unlike MBR, GPT uses a 64-bit logical block address and 128 bytes per unit for partitions that allows it to deal with capacity beyond 2 Tera bytes, and handle up to 9.4 zeta bytes of data.
- It functions well along with the UEFI (Unified Extensible Firmware Interface) based modern systems.
- It uses a special partition on disk which is – EFI (Extensible Firmware Interface) to load the OS, unlike MBR which uses the master boot program.
- It also has an inbuilt mechanism to deal with error detection and resolve error on its own.
MBR v/s GPT Partition in OS
A partitioning scheme in an operating system is a way of structuring and organizing data and partitions in the computer’s storage devices like hard disk drives (HDD) or solid-state drives (SDD).
“To simply put, before we can allocate, store and manipulate data on our storage medium, we need to partition it. We can define the partitioning by using these partitioning schemes”
In this article, we’ll look at two commonly used partitioning schemes in OS: Master Boot Record (MBR) and GUID Partition Table (GPT).
