A Comparison of MBR and GPT Disk Partitioning Styles & How to Find Your Windows 10 Product Key

Disk partitioning is the process of dividing a disk into separate logical units called partitions. Partitions are used to logically separate a disk into distinct sections that can be managed independently. The two most common disk partitioning styles are MBR (Master Boot Record) and GPT (GUID Partition Table). In this blog post, we’ll take a look at the differences between these two partitioning styles and when you might use each one.

The MBR partitioning style was introduced in 1983 with IBM’s Personal Computer/AT system. MBR disks are limited to a maximum of 4 primary partitions, or 3 primary partitions and 1 extended partition. Extended partitions can be further subdivided into logical partitions. MBR disks can be up to 2TB in size. The Master Boot Record is located in the first sector of an MBR disk and contains a boot loader for the operating system as well as information about the disk’s partitions.

GPT was introduced as an alternative to MBR in order to address some of its limitations. Unlike MBR disks, GPT disks can have an unlimited number of primary partitions. GPT disks also do not have a limit on size, so they can be larger than 2TB. The GUID Partition Table is located at the end of a GPT disk and contains information about thedisk’s partitions as well as a CRC32 checksum for verification.

So, which partitioning style should you use? If you need more than 4 primary partitions or you’re working with a disk larger than 2TB, then GPT is the way to go. If you don’t need those extra features, then MBR should work just fine.
