You may wonder: what are the advantages of GPT disk? How to convert MBR to GPT Windows 10? Will convert MBR to GPT erase all the disk partitions? If you want to know the answers to these questions, read the following contents.

The Advantages of GPT Disk

Compared with an MBR disk, a GPT disk has the following advantages.

1. You can create more than 4 primary partitions on a GPT disk.

On a GPT disk, you can create up to 128 primary partitions while on an MBR disk (See: How to Create More Than 4 Partitions on MBR Disk in Windows 10), you are only allowed to create four primary partitions at most or 3 primary partitions and one extended partition (many logical partitions can be created).

2. GPT disk supports up to 18EB in capacity.

GPT disk supports up to 18EB in capacity but MBR disk only supports up to 2TB. If your disk is larger than 2TB, you will find the rest disk space becomesUnallocatedin Disk Management as Windows only recognizes 2TB for an MBR disk.

3. GPT disk has higher security than MBR disk.

Once the partition table is corrupted, MBR disk is unusable. While for GPT disk, it has primary GUID partition table header at the beginning of the hard disk and backup GUID partition table header at the end of the disk. Once errors are detected on primary GPT, it is allowed to recover the whole partition table from the backup GUID partition table header.

Above all, if you want to break those limits on MBR disk or if you have very important files on your disk and are afraid of data loss, you’d better convert MBR to GPT.
