Red Hat Summit3.2. Comparison of partition table types
Partition table types have different properties including maximum partition counts and sizes, with GUID Partition Table and Master Boot Record formats supporting different configurations.
The following table compares the properties of different types of partition tables that you can create on a block device.
This section does not cover the DASD partition table, which is specific to the IBM Z architecture.
| Partition table | Maximum number of partitions | Maximum partition size |
|---|---|---|
| GUID Partition Table (GPT) | 128 | 8 ZiB if using 512 b sector drives 64 ZiB if using 4 k sector drives |
| Master Boot Record (MBR) | 4 primary, or 3 primary and 1 extended partition with 56 logical partitions | 2 TiB if using 512 b sector drives 16 TiB if using 4 k sector drives |
