The newer (GPT) standard solves some limitations of the older (MBR) standard. Here's how to tell which standard your drive uses.

What is a GUID Partition Table, or GPT? In this post, we will see what a GPT partition is and how it compares to MBR disks. We will also learn how to format, remove, or delete a GPT disk or ...

Many high-end games, professional software, and cloud security applications now require Secure Boot and TPM 2.0 features, which are only supported when the system disk uses the GPT partition format.

For example, the maximum partition size of an MBR disk that's formatted with a 512-byte unit allocation size is a measly 2 TB compared to the 9.3 ZB (over 9 billion TB) that GPT disks allow.
