Which One Should I Choose for SSD? MBR or GPT?

When installing and reinstalling the Windows OS on the hard drive, users will be required to choose between two partition styles, namely MBR and GPT. Most users have no idea what's the difference between these two partition styles. And most of the computers are equipped with an SSD now, then which partition style is better for this kind of disk? To answer this question, you need to know what is partition style and the differences between MBR and GPT.

Brief Introduction of MBR and GPT

Both MBR and GPT are partition styles that apply to Windows computers. MBR stands for Master Boot Record, it is the traditional partition style that first came up with by IBM in 1983. MBR consists of three parts: master boot code, a partition table for the disk, and the disk signature. The master boot code stores the installed OS information and a short boot code.

MBR needs to boot from BIOS, and it only works with a maximum size of 2TB on a disk. The partition amount is also limited. MBR only supports users to build 4 primary partitions, or three primary partitions, plus one extended partition. Inside the extended partition, you can create logical partitions to circumvent the partition amount limitation.

GPT stands for GUID Partition Table. It is a more advanced and novel partition style, which didn't appear until the 1990s. GPT needs a UEFI-based system to boot from. And it is not only more compatible than MBR but also supports larger memory than MBR. 

Generally, the number of primary partitions in a GPT disk is unlimited, you can create as many partitions as you want (You can create a maximum of 128 partitions on a GPT, but it is unlikely that you would ever be in such a situation).

In general, there are three differences between MBR and GPT.

  • First, MBR can only boot in BIOS, and GPT can only boot in UEFI.
  • Second, users can only create four primary partitions in MBR but can create a maximum of 128 primary partitions in GPT.
  • Third, MBR can support up to 2TB, while GPT can handle unlimited storage space.

What is Disk Partition? Why Need to Partition a Disk?

To partition a hard drive is actually to process a virtual split of physical hard disk storage space. For example, you can partition a 2TB disk into one bootable partition to install OS and applications, and one data partition to store data. In this case, it means that you can format the system partition and reinstall the operating system without affecting any data on other partitions. 

Partitioning a disk can also help users to create multiple bootable partitions with different operating systems. For example, users could install both Windows and Linux on their computers.

MBR vs GPT, Which One is Better for An SSD?

If you have read the content above, you would understand that whether to choose MBR or GPT has nothing to do with the type of your hard disk. If your computer is UEFI-based, you should choose the GPT partition style. If your computer is BIOS-based, you should choose the MBR partition style. One other thing to notice is if your SSD is larger than 2 TB, it's better to choose GPT partition style.

How to Convert MBR to GPT

In some cases, you might need to convert your disk from MBR to GPT. Generally, you can convert in Disk Management or use Command Prompt. But here we'd like to recommend an easier tool - EaseUS Partition Master.
