When it comes to solid-state drives (SSDs), two different types of partitioning schemes can be used: GUID Partition Table (GPT) and Master Boot Record (MBR). So, which one should you use? Should the second SSD be MBR or GPT? Well, it depends.

  • If you're using an SSD with 2TB or more, you'll need to use GPT.
  • If the SSD capacity is less than 2TB, MBR can be used.

This article will figure out how to choose MBR or GPT for (M.2) SSD with different storage capacities, such as 1TB or 2TB SSD.

In this article, you'll learn:

  • MBR vs. GPT: What Is the Difference?
  • Which Is Better MBR or GPT for SSD? How to Choose?
  • How to Set Up a New SSD, Initialize It to MBR or GPT?
  • How to Convert SSD to MBR or GPT?

MBR vs. GPT: What Is the Difference?


GPT is a newer standard since 2006, while MBR has been around since 1983. GPT is more robust and allows larger drives, but MBR is still a valid option for small drives. Check to know the differences between GPT and MBR from the following four sections:

MBR VS GPT - Partition Numbers:

MBR (Master Boot Record) is limited to having up to four primary partitions. To have more than four partitions, you'll need to create three primary partitions and an extended partition, which can be further subdivided into logical partitions. 

GPT (GUID Partition Table) doesn't have these limitations. It supports up to 128 primary partitions and unlimited numbers of logical partitions.

MBR VS GPT - Disk Capacity:

MBR drives are limited to a maximum capacity of 2TB, whereas GPT drives can be much more significant - 18EB. If you have a large hard drive (3TB or larger), it will need to be formatted using GPT rather than MBR. 

MBR VS GPT - Data Security:

MBR puts boot data and partitions together, while GPT separates data and the system into different partitions. If system corruption happens, it is risky to restore data from the corrupted MBR OS disk.

GPT is far beyond MBR. If one partition is corrupted, you can use other partitions. Moreover, GPT drives offer better data protection, supporting error correction code (ECC). In short, GPT provides more capacity and better data protection.

MBR VS GPT - Operating System Compatibility:

In general, newer versions of Windows are more likely to be compatible with GPT, while older versions are more likely to be compatible with MBR. 

  • MBR is compatible with the Windows operating system before Windows 8.
  • GPT suits higher operating systems: 32-bit Windows 8, 8.1, 10, and 64-bit Windows 7, 8, 8.1, 10, 11.
  • Older operating systems like Windows XP can only use MBR-formatted drives.

You can choose the right MBR or GPT format according to your system and needs. With EaseUS Partition Master, you can easily initialize new SSD to GPT or MBR.

Which Is Better MBR or GPT for SSD? How to Choose?

The answer to the question of which is better, MBR or GPT for SSD, really depends on the capacity of the SSD and the compatibility of the operating system.

  • If the computer supports UEFI boot, and you want to set SSD as OS disk, use GPT.
  • If the computer supports both Legacy and UEFI, set the SSD disk type based on the following tips:

1. Set SSD as OS drive: 

  • Regarding compatibility, if the operating system is Windows 7 or earlier, then MBR is the only option.
  • If the operating system is Windows 8 or laterMBR or GPT can be used.

Notice: When installing Windows, you will be asked to choose between MBR (Master Boot Record) and GPT (GUID Partition Table). If you're unsure which to choose, check if your computer uses BIOS or UEFI. If it's using BIOS, select MBR. If it's using UEFI, select GPT.

2. Use SSD as 2nd disk or data drive:

  • MBR is probably the best option if the SSD is 2TB or less incapacity.
  • If the SSD is greater than 2TB in capacity, GPT is perhaps the better option.

How to Set Up a New SSD, Initialize It to MBR or GPT?

Both two main types of partition tables - MBR (Master Boot Record) and GPT (GUID Partition Table) can be used on a computer. So, how do you set up a new SSD for MBR or GPT?

First, you need to figure out your goal and decide which disk partition style you want to set for your new SSD disk - MBR or GPT.

Then, you can initialize the SSD drive to one of these formats via a free disk partitioning tool, like EaseUS Partition Master Professional.

Note: If you need to set up SSD for Windows migration, you need to learn the disk type of your current OS disk. Click to see free solutions on how to tell if Windows is GPT or MBR.

Here is a quick guide on how to initialize a drive to MBR or GPT:

Step 1. Open EaseUS Partition Master and got to Partition Manager.

Step 2. Right-click the target disk - HDD or SSD and select "Initialize to MBR" or "Initialize to GPT". Click "Execute Task" and "Apply" to save the changes.

How to Convert SSD to MBR or 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.

With this tool, you don't have to be an expert. You just need to follow the simple instructions below, and your disk can be easily converted from MBR to GPT and vice versa.

#2. Convert SSD from GPT to MBR

  • Click "Disk Converter" on the left menu. Select "Convert GPT to MBR" and click "Next" to continue.
  • Select the GPT disk that you want to convert and click "Convert".
  • Wait for the process completes.

Do you know how to choose MBR or GPT for SSD? Whatever your choice is, you can use EaseUS Partition Master to complete the task. By the way, don't forget to share this tutorial if it's helpful.



To decide whether to use an MBR or GPT format for your SSD, it is essential to understand the differences between the two.

  • MBR, or Master Boot Record, is the traditional way of storing information about disk partitions. It is limited to 2 TB or smaller disks and can only support up to four primary partitions.
  • GPT, or GUID Partition Table, does not have this limit and can support more than four primary partitions. However, it is not compatible with some older operating systems and BIOSes.

Therefore, it is vital to check whether your system supports UEFI - GPT before formatting your SSD with this format. Ultimately, both MBR and GPT have advantages and disadvantages, so it is up to you to decide which is best for your needs. And then, you can rely on EaseUS Partition Master to quickly meet your needs.

People are Also Concerned about GPT or MBR for SSD

1. Should a Second SSD be MBR or GPT?

Answer: As mentioned above, if you plan to use the SSD as a second drive, use GPT when the disk is bigger than 2TB, and use MBR when the SSD is smaller than 2TB. 

We recommend GPT, the superior format. Its advantages include unlimited partitions, faster speed, and enormous storage capacities.

2. Should I Use MBR or GPT for 1TB SSD?

As we mentioned above, if your SSD is less than 2TB, MBR is enough for your SSD. 

3. Which is better, MBR or GPT for SSD gaming?

There is no big difference between GPT and MBR besides the partition number and disk capacity. Most geeks suggest that GPT is always better than MBR because GPT is newer, while MBR is not much used any more and because GPT is more widely used on most modern operating systems.
