Linux Filesystem Formats
TLDR: Linux filesystem formats are the structures used to organize and store data on storage devices in Linux operating systems. These formats enable efficient data access, management, and integrity for a wide range of applications, from personal use to enterprise-scale deployments. Common Linux filesystems include EXT4, XFS, and Btrfs, each designed to meet specific performance, scalability, and reliability requirements.

EXT4 is the default filesystem in many Linux distributions, introduced in 2008 as an enhancement of EXT3. It offers robust journaling, backward compatibility, and improved performance for handling large files and partitions. For high-performance environments, XFS, developed by SGI in 1994, excels in parallel I/O operations and scalability, making it a popular choice for enterprise servers. Btrfs, introduced in 2009, focuses on advanced features like snapshots, built-in RAID, and self-healing, catering to modern storage needs.

Specialized filesystems like ZFS and F2FS address niche requirements. ZFS, known for data integrity and scalability, is widely used in storage systems, while F2FS is optimized for flash memory. Linux also supports cross-platform formats such as FAT32 and NTFS for interoperability with Windows. The flexibility and diversity of Linux filesystem formats ensure that users can choose the most suitable option for their specific workload or application.
