Partitioning is a crucial aspect when it comes to configuring and managing storage in Linux. This article aims to delve into the storage options available in Linux and explore the question of how many partitions can be created. By examining various factors such as disk size, partition types, and file systems, this article aims to provide a comprehensive understanding of the limitations and capabilities of partitioning in Linux systems.
Understanding Partitioning In Linux: A Brief Overview
Partitioning in Linux is the process of dividing a physical storage device, such as a hard disk drive (HDD) or a solid-state drive (SSD), into smaller logical sections known as partitions. Each partition functions as an independent unit, capable of storing data and hosting a separate file system.
The primary objective of partitioning is to organize and optimize storage space. By creating multiple partitions, users can isolate different types of data, such as the operating system files and user data, or separate personal and work-related files. Additionally, it allows for easier maintenance and data backup, as the individual partitions can be treated separately.
Linux supports various partitioning schemes, including the traditional Master Boot Record (MBR) and the newer GUID Partition Table (GPT). MBR is the older, more widely supported scheme, while GPT offers advantages such as support for larger storage capacities and more flexibility in partition management.
Understanding partitioning in Linux is crucial for efficient storage management and maximizing the benefits of different storage options available.
Master Boot Record (MBR) Vs. GUID Partition Table (GPT)
Master Boot Record (MBR) and GUID Partition Table (GPT) are two different partitioning schemes used in Linux and other operating systems. The choice between MBR and GPT affects the number of partitions that can be created on a storage device.
MBR is the traditional partitioning scheme used by most older systems. It supports up to four primary partitions or three primary partitions and one extended partition, which can be further divided into logical partitions. However, MBR has limitations in terms of disk size, as it only supports up to 2TB per partition.
On the other hand, GPT is a newer partitioning scheme that overcomes the limitations of MBR. It supports larger disk sizes, up to 9.4 zettabytes, and allows for the creation of up to 128 partitions. GPT also provides better data redundancy and reliability through backup partition tables stored at the beginning and end of the disk.
In summary, MBR is suitable for smaller storage devices or systems that require compatibility with older operating systems, while GPT is the recommended choice for larger storage devices and modern systems.

Primary, Extended, And Logical Partitions: What’s The Difference?
Primary, extended, and logical partitions are different types of partitions that can be created in Linux. Each type serves a specific purpose and has its own limitations.
Primary partitions are the basic type of partitions that can be created on a hard disk. A disk can have up to four primary partitions, and each partition can hold its own file system. These partitions are bootable and can be used for installing an operating system.
Extended partitions, on the other hand, are used to create more than four partitions on a disk. Only one extended partition can exist on a disk, and it can be divided into multiple logical partitions. Logical partitions function like primary partitions but are created inside the extended partition. This allows for an unlimited number of logical partitions to be created.
The main difference between primary and logical partitions is that logical partitions are created inside an extended partition, while primary partitions are created on their own. Additionally, logical partitions cannot be used for installing an operating system.
Understanding the differences between these partition types is crucial for efficient storage management in Linux.
Exploring Storage Options: Hard Disk Drives (HDDs) And Solid-state Drives (SSDs)
When it comes to storage options in Linux, two main types of drives dominate the market: hard disk drives (HDDs) and solid-state drives (SSDs). Understanding the differences and benefits of each can help you make an informed decision for your storage needs.
Hard disk drives (HDDs) are the traditional storage devices that have been around for decades. They consist of spinning platters that store data magnetically. HDDs are known for their large storage capacity and relatively low cost per gigabyte. However, they are slower in terms of data access and have mechanical components that can eventually wear out.
On the other hand, solid-state drives (SSDs) use flash memory to store data, making them significantly faster than HDDs. They have no moving parts, which makes them more durable and less prone to mechanical failure. SSDs are also smaller, lighter, and consume less power, making them ideal for portable devices. However, they are generally more expensive and offer lower storage capacities compared to HDDs.
Deciding between HDDs and SSDs ultimately depends on your specific requirements. If you need high storage capacity on a budget, HDDs are a better choice. However, if speed, durability, and efficiency are your priorities, investing in an SSD would be a wise decision.
Creating Partitions Using The Fdisk Command In Linux
The fdisk command in Linux is a powerful tool that allows users to create partitions on their storage devices. With fdisk, you can conveniently divide your hard disk or solid-state drive into multiple sections to improve data organization and allocation.
To start creating partitions using fdisk, you first need to identify the storage device you want to partition. This can be done by running the command “sudo fdisk -l”, which will display a list of all available disks. Once you have identified the desired disk, you can proceed with the partitioning process.
Using fdisk, you can create primary, extended, and logical partitions, depending on your requirements. You can specify the size and location of each partition, allowing for precise control over your storage allocation. Additionally, fdisk provides options to set partition types, partition bootable flags, and even view partition information.
Creating partitions using the fdisk command enables Linux users to customize their storage layout, improving performance, and organization. Whether you are setting up a new system or managing existing storage, fdisk offers a straightforward and efficient way to create partitions in Linux.
