Simple Way for You to Convert SSD from MBR to GPT

Both of MBR and GPT are the style of partition. For MBR disk, it only sustains four primary partitions and the size of a partition is 2TB. If you need to create more partitions, you can set the fourth partition as extended partition and then you are allowed to build more partitions or logical drives. However, GPT has unique identifies (GUID) to define the partition. With GPT, you can make unlimited partitions on the hard disk. This can help you take full advantage of the disk space.

MBR disks only support up to 2TB partition size and support only four primary partitions. This is the biggest cause that your 4TB hard drive only shows 2TB, the beyond size will cannot be read and displayed. However, GPT has no limitation for partition size and partition on GPT disk has built-in backup which is stored on the end of the disk while the original one is stored on the start. When one of the two is destroyed, you can restore it with the other. Besides, GPT allows unlimited number of partitions. With these advantages compared with MBR, most of users choose to convert SSD from MBR to GPT.
