MBR or GPT : Your Ultimate Pick for Hard Disks

Are you confused about which one to use? MBR or GPT? Read on to decide which one is best for you, we have the best research data on MBR and GPT and which hard disk is right for your system. 

These days with the improvement of technology, the computer has turned into an essential device which is utilized to manage many things in life and work everywhere throughout the world. 

As you most likely are aware, the hard drive is an essential part of the Computer. In case if you are attempting to do a few operations on your hard drive and it’s partitioned, you will most likely go through the terms of “MBR” and “GPT”. In this article, I will present some information about MBR VS GPT and it’s performance on every operating system regardless of Windows, Mac, and Linux. 

What MBR and GPT stands for?

MBR stands for Master Boot Record which helps its user to draw partitions on their hard drive. MBR is the oldest disk partitioning system, It was developed by IBM in 1983 with its computer DOS 2.0. 

GPT(GUID Partition Table) is the latest disk partitioning system which was developed by Intel in the 1990s. GUID Partition Table is a part of UEFI (Unified Extensible Firmware Interface). Intel named GPT as GUID Partition Table as your drive has a globally unique identifier.

Which one to choose MBR or GPT?

In spite of the many convenience points of the GPT-based drive over MBR drives, so many users still use the MBR disk partitioning system since it is still largely utilized in any part of the world.

GPT systems are also picking up the fame by offering more partition space, the number of partitions in Hard drive, and safety.

Windows operating system is now very friendly with GPT system based hard drive which will widen their utilization in big business server farms.

The real contrasts amongst MBR and GPT disk are said above. So you can pick GPT or MBR relying upon what you have and what you want to do.

In my opinion, MBR disk partitioning system is pretty good, but GPT based disk is the best to go with as it is reliable, compatible with all Operating System, and offers you more space.

Read on to know the real difference between two disk partition system and why you should choose to go with GUID Partition Table.


     Master Boot Record (MBR) :

MBR disk has a maximum limit of 2TB and you can make only 4 logical partitions within the drive. MBT disk stores all your partition and boot data together in one place. by any chance, if your data is infected or overwritten, you will face problem recovering all your data.MBR disk is unable to detect any infected file in your drive. 

    Guid Partition Table (GPT) :

GPT drive offers you unlimited space and up to 128 logical partitions in every operating system.GPT disk saves all your data will be multiple partitions across the drive, so it is easier to recover all your data no matter if the data is corrupted or not. Also, GPT drive runs an automatic CRC (cyclic redundancy check) to see if the data in your disk is corrupted or not. GPT drive can automatically detect infected file in your drive and take rapid action to repair it. 

Clear difference between MBR and GPT

After reading the performance section I believe you got the idea about and know the difference between MBR and GPT disk partitioning system. Now it’s time for us to look into this more technically so that you know the clear difference between Master Boot Record and GUID Partition Table. Take a closer look at the picture down below so that you can have a clear idea about it.


From the structure of Master Boot Record, you can know it has a 64-byte split-up table which include four partition table sections and every one has 16 bytes. In this way, every MBR disk partition system user is free to create four disk partition.

Microsoft also allows it’s user to create more partition but can be only up to 128. For a GPT disk partition system, Extensible Firmware Interface (EFI) requires that the partition table ought to be at least 16,384 bytes held, to be specific there is 128 disk partition entry space and each is 128 bytes.

In short, you can make up to 128 essential Partition on a GPT partitioning system. You can see the clear difference between two dynamic disk partition system. GUID Partition Table gives you a backup space which you will not get in MBR disk partitioning system.

Operating System Compatibility

The above article specified MBR and GUID Partition Table in depth, in addition, you additionally need to focus on the compatibility of operating system and BIOS. As a rule, ancient BIOS only work with MBR, however, UEFI works with MBR and GPT, both disk partitioning system. When contrasting MBR and GPT in OS compatibility, you should know every single operating system can work with MBR disk partitioning system, in particular, MBR is very friendly with all versions of all Operating Systems. Be that as it may, despite what might be expected, not all Windows versions work with GUID Partition Table(GPT).

GTP(GUID Partition Table) Supporting Operating systems :

Windows Vista 32 bit

Windows  XP 32 bit

Windows 2000


Mac OS X10.6+

Special note:  Windows 7/8/8.1/10 64 bit Operating System supports GPT Disk as Storage. On a UEFI (Unified Extensible Firmware Interface) Device, you can use Guid Partition Table as a system Drive.

MBR (Master Boot Record) Supporting Operating Systems :

MBR is the oldest Disk partitioning system, therefore, it supports almost all operating system. 

In Windows 7  64-bit and earlier version MBR is the default disk partitioning system. 

Wrapping up : 

Here we have come to the end of this article. After reading this article I believe you got the idea about Master Boot Record and GUID Partition Table.  After reading the performance section
