Since you can only use 2TB of space from a 512B sector hard disk if you initialize it to MBR, you’d better format your disk to GPT if it is larger than 2TB. But if the disk is employing 4K native sector, you can use 16TB space.
Что лучше для SSD-диска: GPT или MBR?
При подключении к компьютеру любого носителя без разметки, будь то твердотельный накопитель или жесткий диск, операционная система Windows предлагает использовать на нем один из двух методов хранения данных — либо основную загрузочную запись (MBR, Master Boot Record), либо таблицу разделов GUID (GPT, GUID Partition Table). Тут у пользователей обычно и возникают вопрос: что лучше для SSD-диска — проверенный временем механизм MBR или относительно новый метод размещения файлов, согласно стандарту формата GPT.
Далее мы рассмотрим различия между MBR и GPT, а также попытаемся выяснить, что лучше всего подходит для твердотельного накопителя в конкретной ситуации. И сразу скажем, хотя формат хранения данных GPT более современен и имеет больше преимуществ, в некоторых случаях предпочтение все же следует отдать использованию основной загрузочной записи MBR.
MBR, GPT и количество разделов диска
Любой пользователь ПК знаком с локальными дисками, которым присвоена буква. В «Проводнике» Windows они по умолчанию прямо так и именуются: «Локальный диск (C:)», «Локальный диск (F:)» и т.д. Эти самые локальные диски и являются разделами. По сути, они представляют собой виртуальные диски, созданные в рамках физического диска. Чтобы имелась возможность записи данных на накопитель, требуется наличие на физическом диске хотя бы одного раздела. Но их может быть несколько. И по их количеству MBR проигрывает GPT.
Основная загрузочная запись MBR может содержать информацию только о 4-х разделах. Т.е. на твердотельном накопителе с MBR можно будет создать четыре «Локальных диска». Впрочем, это ограничение можно и обойти, используя логические разделы. Если требуется, к примеру, чтобы на SSD с MBR было 5 локальных дисков, создаются три «обычных» и один логический, который впоследствии может быть поделен еще на два раздела.
Однако на основе логических разделов нельзя создавать загрузочные тома, т.е. их не получится использовать для установки операционной системы. Для кого-то это является самым большим недостатком в использовании основной загрузочной записи. Но обычные пользователи вряд ли столкнуться с необходимостью создания на физическом диске более 4 томов, чтобы установить систему на 5-й, 6-й или последующий раздел. В большинстве случаев достаточно бывает наличия двух разделов. Если на SSD устанавливается, например, две операционные системы, тогда создаются 3 раздела, 2 — для ОС и один — для хранения файлов.
Использование схемы GPT снимает это ограничение. На SSD-накопителе с таблицей разделов можно создать аж 128 томов без использования логических разделов. Скажем больше, 128 томов — это ограничение продиктовано требованиями Windows (другие операционные системы допускают создания большего числа разделов). Опять же, 128 или даже 10 томов для простых пользователей ПК совершенно ни к чему.
MBR или GPT: дисковое пространство
Твердотельные накопители дороже по сравнению с их механическими аналогами такого же объема, хотя ценовой разрыв продолжает сокращаться. Емкость, предлагаемая потребительскими SSD-накопителями, также продолжает расти. Уже сейчас на рынке доступны устройства емкостью 6 терабайт и более. Емкость диска — это еще один фактор, который поможет определиться с выбором между MBR и GPT.
Если вкратце, основная загрузочная запись не рассчитана на хранения адресов данных, общий объем которых превышает 2,2 терабайта. Другими словами, SSD-диски с MBR емкостью свыше 2,2-х терабайт не смогут хранить данные сверх этого лимита. Оставшаяся часть дискового пространства будет размечена как свободная (неиспользуемая), и туда нельзя будет что-либо записать.
Как уже, наверное, догадался читатель, GPT не имеет таких ограничений. В теории (просто таких физических дисков пока не существует) таблица разделов GUID может хранить адреса данных с общим объемом в 9,4 зеттабайт или более 10 миллиардов ТБ.
MBR, GPT и восстановление данных
Схема MBR хранит все разделы и загрузочные данные в одном месте. Это означает, что если что-то будет повреждено, может возникнуть серьезная проблема, грозящая лишить пользователя, как минимум, части хранящихся на диске файлов. Если какие-либо данные будут повреждены, скорее всего, пользователь узнает об этом только тогда, когда при очередном включении компьютера на экране отобразится ошибка загрузки операционной системы. Восстановление поврежденных данных из главной загрузочной записи MBR возможно, но процедура эта далеко не всегда проходит успешно.
Механизм GPT в этом плане намного лучше, поскольку он хранит несколько копий загрузочных данных сразу в нескольких разделах — как в начале, так и в конце заголовков таблицы. Если один раздел поврежден, GPT может использовать другие разделы для восстановления.
Кроме того, в GPT есть код обнаружения ошибок, который оценивает таблицы разделов при загрузке и проверяет, нет ли в них ошибок. Если те обнаруживаются, то запускается процедура самовосстановления, которая в большинстве случаев завершается успешно.
MBR, GPT и совместимость с BIOS и UEFI
И BIOS, и UEFI представляют собой интерфейсы или наборы микропрограмм, которые отвечают за первоначальную загрузку компьютера. Хотя они оба служат одной и той же цели, между этими интерфейсами имеются существенные различия.
В настоящий момент большинство материнских плат оснащаются гибридными интерфейсами, способными работать, как в режиме BIOS, так и в режиме UEFI. Однако все чаще встречаются платы, оснащенные исключительно новым интерфейсом UEFI.
В плане совместимости MBR имеет преимущества, т.к. этот механизм хранения данные поддерживается обоими интерфейсами. А вот с SSD-накопителя с GPT невозможно загрузиться на компьютере, поддерживающем только интерфейс BIOS.
MBR, GPT и совместимость с Windows
Последняя на момент написания статьи версия операционной системы Windows — 11-я — требует, чтобы ее установка выполнялась только на диск с таблицей разделов GPT. Это также связано и с тем, что данная версия ОС требует наличия интерфейса UEFI. Это также относится и 64-битным версиям ОС Windows, начиная Vista и заканчивая 10-кой. В то же время, 32-битные версии Windows Vista и 7 не поддерживают загрузку с GPT-дисков.
Таким образом, версия операционной системы поможет определиться с выбором между этими двумя механизмами размещения данных.
Однако все рассмотренные ограничения относятся только к использованию твердотельного накопителя в качестве загрузочного диска. Если же его просто подключить к компьютеру в качестве дополнительного хранилища, то операционная система Windows сможет считывать и записывать файлы, независимо от того, какой именно метод хранения данных использовался на SSD-накопителе.
Сделаем выводы
Из всего вышесказанного несложно сделать вывод, что таблица разделов GPT лучше всего подходит GPT. Использование этого механизмы обязательно, если объем SSD-диска составляет больше 2 ТБ. Формат хранение данных GPT более устойчив к повреждениям, имеет больше возможностей в плане создания и управления разделами. И вообще, это более новый и надежный стандарт.
Твердотельные накопители работают иначе, чем жесткие диски, и одним из основных преимуществ является то, что они могут очень быстро загружать Windows, сохранять и считывать данные. Чтобы воспользоваться всеми этими преимуществами в любом случае понадобится система на основе UEFI. Таким образом, когда дело доходит до выбора между MBR или GPT для SSD, второй вариант является более логичным.
А когда все же следует использовать MBR? Тут все просто — только в случае, если с SSD-накопителя будут запускаться старые операционные системы, не поддерживающие загрузку с GPT-диска. Твердотельные накопители лучше подходят для современных операционных систем, таких как Windows 10 или Windows 11. Использование SSD для установки, к примеру, Windows XP и вовсе значительно сократит срок службы устройства по той причине, что эта система не поддерживает функцию TRIM. Да и в плане производительности при обработке данных ставшая уже древней система Windows XP существенно уступает даже Windows Vista, не говоря уже обо всех последующих версиях системы, что попросту перечеркивает преимущества SSD-накопителей.

Need to choose between MBR and GPT
You might ask how to choose partition scheme: MBR or GPT when you initialize a disk for the first time in Windows. Many computer users do not know which one to choose since Windows does not provide extra useful information about them. But don’t worry. Here, we will offer an elaborate introduction of MBR vs GPT to help you make a wise final choice.
GPT is the abbreviation of GUID Partition Table, which is standard for the layout of the partition table on a physical hard disk, using globally unique identifiers (GUID). MBR is another kind of partition table. It is short for «Master Boot Record». Comparatively, the MBR is older than the GPT, thus, it’s more compatible with some previous systems. While GPT is more suitable for later systems.
GPT disks have advantages of partition size, the number of partitions, and resilience. If a computer uses UEFI, it will only support GPT as the system disk, especially since Microsoft announced officially that Windows 11 system will only support GPT and UEFI. Thus, the GPT disk becomes one of the essential Windows 11 requirements. If you’re thinking about upgrading your Windows 10 PC to Windows 11, it may be necessary to convert MBR to GPT at first.
MBR vs GPT: what’s the difference?
An MBR disk can be basic or dynamic, just like a GPT disk can be basic or dynamic. Compared with an MBR disk, a GPT disk performs better in the following aspects:
▶ GPT supports disks larger than 2 TB in size while MBR cannot.
▶ The GPT disk partitioning style supports volumes up to 18 exabytes in size and up to 128 partitions per disk while the MBR disk partitioning style supports volumes up to 2 terabytes in size and up to 4 primary partitions per disk (or three primary partitions, one extended partition, and unlimited logical drives).
▶ GPT disk provides greater reliability due to replication and cyclical redundancy check (CRC) protection of the partition table. Unlike MBR partitioned disks, data critical to platform operation is located in partitions instead of unpartitioned or hidden sectors.
▶ GPT partitioned disks have redundant primary and backup partition tables for improved partition data structure integrity.
For more information about the differences between GPT disk and MBR disk, please go to The Differences between MBR and GPT.
Usually, MBR and BIOS (MBR + BIOS), and GPT and UEFI (GPT + UEFI) go hand in hand. This is compulsory for some operating systems (eg. Windows), while optional for others (eg. Linux). When it comes to converting a system disk to a GPT disk, make sure that your computer’s motherboard supports UEFI boot mode.
How to change partition scheme between MBR and GPT in Windows PC?
After learning information about MBR VS GPT, you might need to make a conversion for the current partition style, from MBR to GPT, or GPT to MBR. Here in Windows, you have two ways to complete that, Windows built-in tools and third-party software.
① Convert to GPT/MBR disk via Windows built-in utilities (Data Loss)
With Windows Disk Management and Diskpart tools, you’re allowed to convert an EMPTY hard disk to MBR or GPT with ease. That is to say, you need to delete all existing partitions in the first place. Therefore, back up important data to a safe place in advance and then follow the steps below. Here takes convert to GPT using Diskpart for example.
Step 1. Press «Windows» + «R» simultaneously to lift the «Run» box. Input “diskpart” and press Enter.
Step 2. At the DISKPART prompt, input the following commands successively, and each command follows «Enter» pressing.
▪list disk
▪select disk n (where n is the disk number of target disk)
▪clean (this command will erase the entire disk)
▪convert gpt (or convert mbr)
▪exit
Note: You may not convert system disk to GPT under Windows environment since the system partition cannot be deleted when Windows is running. To change the system disk, you need to enter WinPE mode and perform the conversion.
② Convert to GPT/MBR without data loss via professional software (System Disk Included)
Since the Windows native tools can only convert an empty disk to MBR and GPT, it is not ideal for users who have stored lots of data on the target disk. Therefore, next, we’d like to show you a good way to convert MBR to GPT without data loss. That is using the third-party software: AOMEI Partition Assistant Professional. The powerful hard drive manager allows you to convert between MBR and GPT on both system disk and data disk without deleting partitions in simple clicks. Here is a step-by-step guide.
Secure Download
In the first place, you can download AOMEI Partition Assistant Professional Edition Demo (only for simulation) from its official website. Install and run. Here we will take convert MBR to GPT for example.
Note : to avoid data loss caused by improper human operations and other unexpected issues (power failure. ), it is better to back up everything you require.
Step 1. Right-click the MBR disk that you want to convert to GPT and choose Convert to GPT Disk.
Step 2. You’ll be asked that «are you sure to convert the selected disk from MBR to GPT disk?». Click OK.
Step 3. To commit operation, please click Apply.
Notes :
1. A removable disk is also allowed to convert.
2. Converting system disk to GPT partition style requires 64-bit operating systems. Note that Windows XP 64bit can only use GPT disk for data storage.
3. After converting a system disk from MBR to GPT, or GPT to MBR, you have to change the boot mode from UEFI to BIOS, or Legacy BIOS to UEFI for a smooth boot.
Some FAQs on MBR and GPT
▶ Is Windows 10 GPT or MBR?
From the reliability and CRC protection mentioned before, it is suggested to use the GPT partition style if all other conditions are qualified.
▶ Should my SSD be MBR or GPT?
Usually, SSDs are used to install operating systems. All Windows operating systems can be installed on MBR disks yet some of them cannot be installed on GPT disk. Windows 8 and higher operating systems are required as shown in the first figure.
▶ Can UEFI boot MBR?
Yes. UEFI supports the traditional master boot record (MBR) of hard drive partition, but you may not use Legacy boot GPT on the contrary.
▶ When need to convert GPT to MBR disk?
Some situations need to convert GPT to MBR. One is like the problem — “the Selected Disk is of the GPT Partition Style” when people install Windows system. People can also convert GPT to MBR disk with the aid of AOMEI Partition Assistant Professional Edition.
Conclusion
Now, you should get an overall understanding of MBR VS GPT and know how to convert MBR to GPT, or GPT to MBR via different methods. All in all, with the AOMEI Partition Assistant software, you can easily and safely make conversions between MBR and GPT without losing anything important. It is a great partition converter, not only between MBR and GPT but also between FAT32 and NTFS, primary partition, and logic partition. It can even rebuild MBR when the master boot record is corrupted and causes boot failure.

From the screenshot you can see I have 2 disks: one MBR and one GPT.
Since MBR and GPT are partitioning schemes, they are doing the same thing: manage how partitions are created and organized on a hard disk, but they differ from each other in many aspects.
Let’s see the following paragraphs to learn some information about MBR vs. GPT.
Firstly, MBR and GPT Were Introduced in Different Time
MBR was introduced with IBM PC DOS 2.0 in March 1983 and it is used till now. However, GPT was developed in the late 1990s as part of what eventually became UEFI, and it becomes popular just in recent years.
GPT и MBR изменение схемы разделов диска.
Secondly, MBR and GPT Have Different Structures
MBR consists of 3 parts, including master boot code, a partition table for the disk, and disk signature. A partition table can hold maximum number of 4 entries for primary partitions in Windows.
However, a GUID Partition Table is composed of a Protective MBR which is used in a way that prevents MBR-based disk utilities from misrecognizing and possibly overwriting GPT disks, a primary GUID partition table header which records its own size and location and the size and location of the secondary GPT header, a primary GUID Partition Entry Array, a backup GUID Partition Entry Array, and a backup GUID Partition Table Header. A GUID partition table could contain up to 128 partition entries in Windows.
From the above, you can know a major difference between MBR and GPT, which are the primary partition number on the HDD or SSD. So, if you choose to set MBR or GPT for SSD.
Thirdly, Supports on Disk Capacity and Partition Amounts Are Different
Support on Partition Amounts
Since an MBR partition table can hold 4 primary partition entries at most, you are only allowed to create the maximum number of 4 primary partitions on an MBR disk. If you want to create more partitions, you have to create an extended partition where lots of logical partitions could reside. However, a logical partition can’t be set active.
On the contrary, a GPT disk theoretically allows an almost unlimited number of partitions, but Windows implementation restricts it to 128 partitions. Each partition on GPT can function like a primary partition on MBR disk.
Free Download Rufus 3.19 for Windows 11/10 and Introduction
In this post, we will show you how to download Rufus 3.19 for Windows 11 and Windows 10, and the new features in this new version.
Support on Disk or Partition Capacity
You can only use 2TB or 16TB of a hard disk’s capacity no matter how large the disk is, if you initialize it to MBR. If the disk is using the traditional 512B sector, you can only use 2TB. If it is using 4Kn (4K native) sector, you can use 16TB.
However, a GPT disk can be up to 2^64 logical blocks in length, and logical blocks could be 512 bytes or 4K in size. Therefore, a GUID partition table disk can grow to a very large size compared with MBR partition table disks. Actually, there is no need to talk about disk or partition capacity limit of GPT since there will be no hard disk exceeding the limit in a very long time.
Fourthly, MBR Differs from GPT in Compatibility
All current Windows operating systems can use GPT partitioned disks for data, such as Windows 7, Windows 8, Windows 10, Windows Server 2008, Windows Server 2012, and Windows Server 2016, but only their 64 bit versions support booting from GPT disk when UEFI boot mode is supported and enabled.
In addition, the 32 bit version of Windows XP can only see the Protective MBR, and even the 64 bit version can use GPT disk for data only.
At Last, They Have Different Boot Mode
If motherboard of your computer supports Legacy boot only, you can only boot Windows from MBR disk. To install Windows on GPT disk under this mode, you’ll receive the error message » Windows cannot be installed to this disk. The selected disk is of the GPT partition style «.
Or Windows won’t start if it is already installed on GPT disk under Legacy boot mode.
However, if motherboard of your computer supports UEFI boot only, you can only start Windows from GPT disk. To install Windows on MBR disk, you’ll receive the error message «Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disk» .
Similarly, Windows will be unbootable if it is already installed on MBR disk in UEFI boot mode.
But luckily, current motherboards support both Legacy boot and UEFI boot, so you only need to enable the CSM (Compatibility Support Module) in BIOS when you want to boot Windows from both MBR disk and GPT disk, or enable UEFI when you want to boot from GPT disk, or enable Legacy BIOS while you plan to boot from MBR disk.
In addition, even if your motherboard supports one boot mode only, you can still find solutions from the article Windows Cannot Be Installed to a Disk? Here Are Solutions.
Then, let’s talk about which partitioning scheme is better, MBR or GPT.
How to Download and Install Windows 11 on Arm with ISO?
This post will tell you how to download and install Windows 11 on Arm with ISO, as well as some related information about Windows Arm-based PCs.
MBR vs. GPT: Which One Is Better or Which One to Choose
Please read all contents in this part and then choose the most proper partitioning scheme for your SSD, HDD, or even removable device.
GPT is better if you are planning to create more than 4 partitions.
We have said an MBR disk can hold 4 primary partitions at most while a GPT disk supports up to 128 primary partitions in Windows, so you can choose GPT if you want more partitions.
Note: A dynamic disk also supports up to 128 partitions, so you can choose either Dynamic Disk or GPT disk if you demands for more partitions only.
But note on dynamic disk Windows can only be installed to a volume that was converted from a basic partition and retained an entry in the partition table. Simple volumes converted from basic partitions do not have an entry in the partition table unless they were system or boot volumes prior to conversion. This information is required to perform fresh installations of on dynamic volumes.
GPT is better than MBR if your hard disk is larger than 2TB.
Since you can only use 2TB of space from a 512B sector hard disk if you initialize it to MBR, you’d better format your disk to GPT if it is larger than 2TB. But if the disk is employing 4K native sector, you can use 16TB space.
Tip: even if your MBR disk is saving data, you still have a chance to convert it to GPT without data loss. Detailed steps will be introduced in the last part of this post.
GPT is better if you seek for security.
GPT disks use primary and backup partition tables for redundancy and CRC32 fields for improved partition data structure integrity, so you can choose this partitioning scheme if you value data security.
Choose GPT rather than MBR for your system disk if UEFI boot is supported.
Compared with booting from MBR disk, it’s faster and more stable to boot Windows from GPT disk so that your computer performance could be improved, which is largely due to the design of UEFI. Please remember to enter your computer’s BIOS and enable UEFI boot if it isn’t.
Choose MBR for system disk if your motherboard doesn’t support UEFI boot.
Under Legacy boot mode, you can only initialize your system disk to MBR if you want Windows bootable.
Choose MBR as system disk if you have a 32 bit Windows to install.
Only 64 bit version of Windows can boot from GPT disk.
Choose MBR for system disk if you are still using the very old Windows OS.
If you are running Windows XP or older systems, MBR is the only choice for system disk even if it is a 64 bit system. If not, Windows will be unbootable or cannot be installed.
Well, knowing the differences between MBR and GPT, how can you initialize GPT or MBR for SSD or HDD, or convert a disk that already saves data between MBR and GPT without losing data? These are what we will talk in the following part.
MBR vs. GPT: How to Initialize or Convert Disk Without Data Loss
How to Initialize Disk to MBR or GPT
It’s very easy to initialize a MBR or GPT for SSD or HDD, which could be done in both Windows Disk Management and MiniTool Partition Wizard.
In Disk Management:
Press on Win and R key to open Run and type diskmgmt.msc to launch Disk Management. Then, you’ll be asked to initialize the newly added hard disk, where you can choose either MBR or GPT.
In MiniTool Partition Wizard:
Launch the program to get its main window:
MiniTool Partition Wizard initializes the newly added disk to MBR by default, but you can select the disk and choose «Initialize to GPT Disk» or «Convert MBR Disk to GPT Disk» feature from the left action panel to convert the disk to GPT if you want GPT.
At last, click Apply» button to perform the change.
But what if the disk has been saving lots of data?
How to Convert Disk to MBR or GPT without Data Loss
In Disk Management:
In this case, if you also turn to Disk Management, you’ll need to backup important files, and then delete all existing partitions. If not, the option «Convert to GPT Disk» or «Convert to MBR Disk» will be grayed out:
Note: if you want GPT disk just for creating more partitions, converting MBR disk to dynamic disk is better than converting to GPT, because the former doesn’t require deleting partitions. But if you want to break the 2TB limit or pursue other features of GPT, convert it to GPT.
In MiniTool Partition Wizard:
Alternatively, you can use MiniTool Partition Wizard to do the conversion, which can keep your data and partition intact.
Firstly, launch the program to get its main window:
Then, select the MBR or GPT disk that you want to convert, and choose «Convert MBR Disk to GPT Disk» or «Convert GPT Disk to MBR Disk» from the left action panel.
At last, click Apply» button to execute the change.
Note: MiniTool Partition Wizard is also capable of converting system disk from MBR to GPT with keeping Windows bootable, but converting system disk to GPT should be on the basis that UEFI boot is supported and enabled in your BIOS.
Bottom Line
Now, all information about MBR vs. GPT is told to you and you would know which partitioning scheme is better to choose. It’s time to initialize GPT or MBR for SSD or HDD or convert old HDD/SSD between MBR and GPT based on the actual needs.

MBR VS GPT FAQ
Is GPT or MBR better?
MBR (Master Boot Record) and GPT (Guide Partition Table) are two different styles that help the system to manage your disk partitions. MBR is a disk partition standard began operating in 1983 and is still functional today. MBR disk has good compatibility and it is compatible in most operating systems.
The MBR format disk has some limitations. It is only capable of handling disks of up to 2TB and supports only 4 primary partitions. However, on GPT disk, you can have more than four primary partitions on each disk, which can be up to 128 partitions.
What is the difference between MBR and GPT?
MBR and GPT are two different ways to store the partition information on a hard drive. MBR and GPT disks have some differences and limitations. For MBR disk, it can only work with the disk up to 2TB and supports up to four primary partitions. However, the capacity of GPT disk can be larger and up to 128 partitions can be created. Windows can only boot from GPT on UEFI-based computers running a 64-bit version of Windows 10, 8, 7 Vista and corresponding Server editions.
Should my SSD be MBR or GPT?
In general, the legacy BIOS only supports MBR, but the UEFI supports MBR and GPT. So, when selecting the MBR or GPT disk, you can take the OS support into consideration. All operating systems can be installed on the MBR disk. However, all Windows versions can use GPT partitioned disk to store data, but booting is only supported for 64-bit editions on UEFI-based systems.
Should I choose MBR or GPT?
If your disk is more than 2TB and you want to manage more than 4 primary partitions on a hard disk, you can choose to format the disk to GPT. When selecting MBR or GPT, you also need to check whether your computer uses BIOS or UEFI. BIOS only supports the MBR, but the UEFI supports the MBR and GPT.
