    Study Notes

    File Systems Overview

    • macOS prioritizes Apple File System (APFS) for its modern features and performance benefits.
    • macOS also supports HFS Plus for older systems and compatibility reasons.
    • Windows uses FAT32, NTFS, and exFAT file systems.
    • Linux is highly versatile with file systems like EXT4, Btrfs, XFS, F2FS, Bcachefs, ReiserFS, and Reiser4.

    Ext4

    • Default for many Linux distributions.
    • Offers excellent performance, reliability, and stability, supporting files up to ~6.6 terabytes.

    Btrfs

    • Modern file system with advanced features like snapshots, RAID support, and data integrity checks.
    • Offers excellent performance for large files and volumes.

    XFS

    • Optimized for high-performance and scalability.
    • Excels in handling large files and file systems.

    F2FS

    • Optimized for NAND flash memory-based storage devices.
    • Improves performance and longevity for flash storage.

    Bcachefs

    • Aims to combine features of a modern COW (Copy-On-Write) filesystem with traditional filesystems.
    • Offers features like checksumming, compression, and encryption.

    FAT32

    • Utilizes a file allocation table to organize data on a drive.
    • Uses clusters of blocks, the size of which varies depending on the partition size.
    • Has a limited file size (smaller than or equal to 4 GB) and partition size (up to 32 GB).

    NTFS

    • Uses clusters of blocks and a Master File Table (MFT) for improved organization and efficiency.
    • Supports partitions up to 16 TB on a dynamic disk and 2 TB on a basic disk.
    • Offers advanced features like security, compression, encryption, and disk quotas.

    exFAT

    • Developed by Microsoft to address limitations of FAT32 and NTFS.
    • Supports larger files and volumes, making it suitable for external storage devices.
    • Offers improved performance and streamlined design for flash storage.
    • Widely compatible across various operating systems.

    Key Differences between FAT32, NTFS, and exFAT

    • FAT32: Simple, less resource-intensive, and limited file size, ideal for older devices.
    • NTFS: Feature-rich, supports larger file sizes and various security features, recommended for internal drives.
    • exFAT: Versatile for large files and volumes, suitable for flash drives and external drives.

    Use Cases for File Systems

    • FAT32: Widely compatible for smaller storage devices and older systems.
    • NTFS: Ideal for internal drives, offers better performance and security features.
    • exFAT: Preferred for external drives and cross-platform file sharing, supports large files and is compatible with various devices.
