Windows GPT Disks – Is Bigger Really Better?

Bruce Mackenzie-Low examines the benefits and disadvantages of MBR and GPT-based Windows disks. The 2 approaches differ in how they track the mapping of physical disk sectors to logical block numbers. MBR (Master Boot Record) is widely accepted, but partition size is limited to 2 terabytes. GPT (GUID Partition Table) was created to accommodate the larger partition sizes and offers greater resilience to corruption.
