When using a single disk, has to decide the partition method to be used, and nowadays, it could be either MBR or GPT (GUID Partition Table). The first is older, and it is dated from the decade.

The partition may help to address some common issues, such as the use of different file systems, logical separation of data, and so forth.

The MBR is older, and it has some limitations, such as the maximum of four primary partitions in a disk, or three primary and one extended that allows 12 logical partitions. However, the maximum partition size is 2TB. The GPT is more flexible, allowing 128 partitions out of the box and virtually 8 zebibytes (ZiB)
