I am setting up a new server and I am designing the server for performance over capacity. Planning the disk partitioning style I would like to use GPT over MBR but am not sure which is best. I am using SAN attached storage.

Which partition style, MBR or GPT, is better for a SQL Server 2008 R2 implementation?


MBR cannot handle partitions bigger that 2 TB, thus if your partition is bigger than 2 TB you have to use GPT. There is no performance gain as far as I know. It's all about the capacity!
