MBR and GPT are two different partitioning schemes used on hard drives and other storage devices.
MBR (Master Boot Record) is an older partitioning scheme that was widely used on PCs and other devices until the development of GPT (GUID Partition Table). MBR partitioning allows for up to four primary partitions, or three primary partitions and one extended partition containing logical drives. MBR partitioning also uses 32-bit sector addressing, which limits the maximum size of a partition to 2 TB.
GPT (GUID Partition Table) is a newer partitioning scheme that is becoming more widely used. It supports up to 128 partitions, and can use 64-bit sector addressing, which allows for much larger partitions, up to 9.4 zettabytes in size. GPT partitioning also provides redundancy by storing multiple copies of the partition table throughout the disk, which helps to protect against data loss.
In addition, GPT partitioning is required for UEFI boot mode, which is increasingly common on newer systems. UEFI boot mode is a replacement for the older BIOS boot mode and allows for faster boot times, improved security features, and better support for modern hardware.
In summary, while MBR partitioning is still commonly used on older devices and systems, GPT partitioning is becoming more widely adopted due to its support for larger partitions and increased redundancy, as well as its compatibility with UEFI boot mode.
