You can’t use the space beyond 2TB of MBR disk while GPT supports much large disk size.
Windows 11 uses UEFI boot mode, which require the boot drive to be GPT partition style.
MBR allows 4 primary partitions while GPT supports up to 128 partitions for complex partitioning schemes.
GPT disk takes measures to prevent data loss due to partition table corruption, enhancing data security and integrity.
Converting disk to GPT is more sustainable storage solution for future hardware and software advancement.
GPT supports disk encryption, dynamic disk configuration and large sector size for better disk performance.
