Choosing GPT instead of MBR for the system disk can bring a number of benefits, especially if booting with UEFI is supported. GPT provides improved performance and reliability for hard drives, as it increases the storage capacity, improves the speed of access to data, and provides better error correction and recovery capabilities. It also allows larger units to be used, which increases the amount of data that can be stored. For faster boot times, it is recommended to use a GPT disk as the system disk; if the computer is BIOS-based, choose MBR as the system disk; while if you use a disk of less than 2 TB for data storage, both GPT and MBR work well.
Windows 11 will only support GPT and UEFI, so if you are using a newer operating system, you should use GPT. Note that only new operating systems can use the GPT disk; for example, Windows XP 32-bit does not support the GPT disk. GPT disks automatically back up the main GPT header and partition entries in the last sectors of the disk. This MBR protector prevents tools that only support MBR disks from erroneously recognizing and overwriting GPT disks.
You can perform the conversion between MBR and GPT without data loss or partition a hard drive to a GPT or MBR partitioning scheme. In conclusion, GPT is an important technology for improving the performance and reliability of hard drives. It increases storage capacity, improves speed of access to data, provides better error correction and recovery capabilities, and allows larger units to be used. It also offers faster boot times when compared to an MBR disk.
