The Disk Formatting Process

Choosing the Right File System
When choosing a file system, it is important to consider the intended use of the storage device. Some factors to consider include compatibility with other devices and operating systems (Windows/Mac), file size capacity, and the need for advanced features such as file encryption or compression. It is also important to note that different file systems have different performance characteristics, so it may be necessary to benchmark the device with different file systems to determine which one provides the best performance for your specific use case. (Discussing in future course)

Common File Systems
NTFS − (New Technology File System) 
NTFS is the default file system used by Windows NT-based operating systems, starting in 1993 with Windows NT 3.1, all the way up to and including Windows 11. It offers advanced features like file permissions, encryption, compression, and journaling. NTFS supports large file and partition sizes, making it suitable for modern storage devices. However, it has limited compatibility with non-Windows operating systems.

FAT32 − (File Allocation Table 32) 
FAT is one of the oldest and simplest file systems. It was initially developed for MS-DOS and is still used in many removable storage devices. The two major versions of this system are FAT16 and FAT32. FAT uses a file allocation table to keep track of file locations on the disk. However, it lacks some advanced features like file permissions and journaling, making it less suitable for modern operating systems. FAT16 was introduced in 1987 with DOS 3.31, while FAT32 was introduced with Windows 95 OSR2(MS-DOS 7.1) in 1996. It is compatible with Windows, Mac OS, and Linux but has limitations such as a maximum file size of 4GB.

exFAT − (Extended File Allocation Table) 
exFAT file system introduced by Microsoft as an improved version of FAT32. It addresses some of the limitations of FAT32, allowing for larger file sizes and better performance. exFAT is commonly used for removable storage devices, such as external SSDs, hard drives, and SD cards as it provides compatibility across multiple operating systems. It was first introduced in 2006 as part of Windows CE 6.0.

Ext4 - (Fourth Extended File System)
A widely used file system in the Linux operating system. It is the successor to Ext3 and offers several improvements in terms of performance, scalability, and reliability. Ext4 is the default file system for many Linux distributions. It was first introduced in 2003.

HFS+ (Hierarchical File System Plus) 
HFS file system initially used by Apple computers. It has since been replaced by HFS+ and APFS. HFS uses a hierarchical directory structure and supports features like metadata and resource forks for storing additional file information. It is compatible with older Mac systems. HFS was introduced in 1986 with System 2.1 for the Mac Plus. HFS+ was introduced in 1998 with Mac OS 8.1 and phased out in favor of APFS in 2019 with macOS 10.15.

APFS (Apple File System)
APFS is a file system developed by Apple for macOS, iOS, and other Apple devices. It is designed to optimize performance and compatibility with Apple's hardware and software. APFS includes features like cloning, file-level encryption, and improved performance on solid-state drives. It was introduced with macOS 10.13 in 2017
