What are the pros and cons of Uefi+gpt and bios+mbr?

1, the number of partitions, GPT seems to be able to support unlimited partitions, but only 128 on window, and the GPT partition is not divided into primary partition, logical partition, it can be understood that all are primary partitions, it is equivalent to allow you a partition of a system, 128 systems. And this is the MBR can not do, MBR only have four systems, if you want more than four partitions, it will have to sacrifice to install a system of the primary partition, that is, to replace it into a logical partition.
2, security, GPT will be more secure, because the partition table will be backed up, and join the validation algorithm, once the virus infection or misuse can be found in time, using a secure backup of the partition table remediation.
3, the partition capacity, GPT can identify more than 2T hard disk, and MBR maximum 2t capacity

For UEFI and BIOS, UEFI supports modular development, which facilitates vendor-to-firmware development.
Security, because there are more specialized EFI partitions, and the partition is not displayed in the system, to a certain extent, improve security.
Speed, because the BIOS has a hardware self-test at boot time, and this function is implemented in the EFI partition, the UEFI is relatively fast to boot. --------UEFI+GPT is not a hard disk to produce more than two hundreds of m of small partition Ah, look comfortable oh yes an MSR, that is, Microsoft Reserved partition, basically useless, but some time the system upgrade needs to detect the existence of the partition. An ESP, the EFI system partition, is the EFI boot system partition that holds the boot files for each system on the hard disk to boot the system. Both are FAT or FAT32 partitions, normal use, the system will not assign the drive letter to the two partitions, only the partition software is visible under the two partitions.
