Choosing Between Partition Schemes
The main considerations for choosing between the partition schemes are
hard
drive size, operating system version, and software tools used in the
operating system.
The MBR partition scheme is used across older versions of Microsoft operating
systems, legacy software tools that only recognize MBR partitions, and hard
drives smaller than 2 TB. For newer operating systems such as Windows Server
2008 R2, Windows Server 2008, or Windows Small Business Server 2008 and
hard drive sizes larger than 2 TB, use the GPT partition scheme.
It is recommended that you use the GPT partition scheme as it is more
flexible, supports larger hard drive sizes, and has a number of features and
recovery mechanisms that are not available in the MBR partition scheme.
