MBR VS GPT – Which One is Better To Choose?

The comparison between MBR vs GPT partitions is pronounced. However, there is a wide range of background knowledge available to help you understand each type of system partition and when you should use one over the other.

In this article, we’ll see what a partition is, MBR vs GPT partitions if you need to update from one kind to another, and much more in this post.

What exactly is a partition?

A partition is a logical separation of a hard disk or solid-state device (SSD). Each division can be a different size and has a distinct purpose.

In Windows, for example, a tiny recovery disc and a huge file system partition called C: are frequently present. Many individuals are familiar with the C: partition, where you can install your programs and store their multiple files.

A root partition (/), a swap partition (which aids memory management), and an extended/home partition are standard in Linux. The /home partition gets comparable with Windows C: drive in that it is where most of your applications and files are installed.

The manufacturer takes care of the partitions once you purchase your computer from a retailer with the system software already installed. Unless you wish to dual-boot Windows and Linux from the same HDD or SDD, you don’t need to bother about them.

Although if you install the operating system manually, the installer will usually advise default partitions and sizes. You shouldn’t have to make any changes in most cases.

We can delve more profound into the MBR vs GPT partitions now that you have a high-level grasp of a partition.

Precisely what is MBR?

Master Boot Record determines how hard disc partitions get built and organized (HDD). MBR is based on Bios firmware and contains code in the first sector of the disc, with a logical block address (LBA) of 1. The information pertains to how and where Windows manages the boot process in the PC’s storage medium and inner random access memory (RAM), rather than external storage such as DDR2 and DDR3 memory cards and sticks.

The MBR data on hard disk LBA 1 includes the following:

Master Partition Table

The MPT (Master Partition Table) contains all partition information on each hard drive, including format type, capacity, and other relevant information. The Operating System and PC need to have a record of HDD partitions and size, as well as a mechanism to identify the booted, active partitions to function correctly. The MPT contains all of the necessary information.

Master Boot Code

The MBC code conducts the operating system’s startup. It keeps the startup process setting (to confirm any changes), such as identification discs, estimating RAM (external), recognizing displays, and other important device and configuration data.

Disk Signature

Every drive requires a unique identification, which gets generated as a signature. When multiple discs get used, this identification guarantees the correct drive and partition reading and writing data and adequate PC capability and security protocol for all read/write transaction data.

The basic input/output system (BIOS) on the PC/motherboard looks for a disk with an MBR and then runs the volumes boot code from that partition. The MBR then boots the disk boot sector to boot the operating system.

What is a GPT Partition, and how does it work?

It stands for GUID Partition Partition Table. It oversees the formation and organization of partitions on the hard disk, similarly to MBR. GPT employs UEFI firmware and, like MBR in sector one, holds disc information like partitions, volumes, and other critical data. However, since sector one got allocated for MBR and BIOS compatibility, GPT uses sector two.

GPT is sector 1 in GPT terms (LBA 1) and MBR sector #1 (LBA 1) is LBA 0 for GPT.

The disc information gets stored in the GPT header in the manner of a GUID partition table. The GUID contains information on partitions, drives, boot information, storage sizes, and other boot and functionality-related data.

The GUID Partitions Table in LBA 1 of the HDD provides the following information:

  • GPT data
  • MBR data
  • Data partition entries
  • Supplementary (a.k.a. backup) GPT data

MBR vs GPT – What is the difference?

The fundamental distinction between MBR vs GPT is that MBR has several modern-day limitations. An MBR disc can be dynamic or primary, just like a GPT disc. Compared to an MBR disc, a GPT disc stands out  in the following areas:


GPT can handle discs up to 2 TB in capacity, whereas MBR cannot.

    • The GPT disc partitioning style allows for volumes up to 18 exabytes in size and up to 128 partitions per disc. Contrary, the MBR disc partition style enables volumes of up to 2 terabytes in the capacity and up to 4 primary partitions for disc (or one extended partition, three primary partitions, and unlimited logical drives).
    • Due to partition table replication and cyclical redundancy check (CRC) protection, GPT discs are more reliable. Data vital to platform functioning gets stored in partitions rather than unpartitioned or concealed sectors, unlike MBR partitioned drives.
    • For increased partition data structure integrity, GPT partitioned discs contain multiple primary and backup partition tables.
    • In addition to the previous MBR vs GPT differences, GPT can take advantage of more recent hardware techniques and supports BIOS/MBR features for compatibility with earlier, non-UEFI appliances. Lastly, with UEFI and GPT, booting is much quicker.
    • In GPT vs MBR windows 10, GPT is compatible, whereas windows below 8 are only compatible with MBR.

Which one is better – GPT or MBR?

GPT (Guide Partition Table) and MBR (Master Boot Record) are two alternative methods of disc partition management that the system uses. MBR is a disc partitioning standard first implemented in 1983 and is still in use today. MBR discs get widely compatible and can get used in various operating systems.

There are certain restrictions to the MBR format disc. It can only handle disks up to 2TB and only supports four primary partitions. On a GPT disc; however, you can have up to 128 primary partitions on each drive, rather than only four.

Should I use MBR vs GPT SSD?

SSDs differ from HDDs in that they can start Windows quickly, which is one of their key advantages. While MBR and GPT both work well in this situation, you’ll need a UEFI-based system to use the higher speeds. When you select between MBR and GPT for SSDs, GPT is all the more logical choice due to compatibility. This is true regardless of the form factor of your SSD, such as M.2.

Should I go with the MBR or the GPT?

If your hard disc is more than 2TB and you wish to handle more than four primary partitions, you can convert it to GPT. You should also check if your computer is running BIOS or UEFI when choosing MBR or GPT. BIOS only supports the MBR. However, both the MBR and GPT get supported by UEFI.


you understand the differences between MBR and GPT. You can appropriately choose the partition table plan that truly works for your HDD or SSD size, preferred number of partitions, and OS now that

While most of the technical differences may appear confusing to comprehend and apply, keep in mind that MBR got built to assist drives smaller than 2TB and older operating systems. In contrast, GPT got developed to facilitate drives larger than 2TB, newer operating systems, and a more incredible group of partitions.
