1. File Size Limitations – Fat32 File Size Limitation
- FAT32 Limitation: FAT32 has a maximum file size limit of 4 GB. This means that any single file larger than 4 GB cannot be stored on a FAT32-formatted drive. This is a common issue when dealing with modern operating systems, large disk images, or other substantial files.
- NTFS Advantage: NTFS (New Technology File System) supports much larger file sizes, effectively removing the 4 GB limit. If your ISO file or any other files you plan to use exceed 4 GB, you will need to format the USB drive to NTFS.
2. Compatibility with Modern Systems
- FAT32 Compatibility: While FAT32 is widely compatible with a variety of systems (Windows, Linux, macOS, and even some embedded systems), it lacks some of the features and security advantages provided by NTFS. However, FAT32 is still useful for maximum compatibility across different operating systems, particularly older or more basic systems.
- NTFS Features: NTFS offers several advanced features such as file compression, encryption, larger file sizes, and better error recovery. These features are often essential when dealing with modern operating systems or specific applications that require these capabilities.
3. Installation Requirements
- Operating System Requirements: Some operating systems or installers require the USB drive to be formatted with NTFS, particularly when dealing with newer Windows installations. For example, Windows To Go, a feature in Windows 10 Enterprise, requires an NTFS-formatted USB drive to work properly.
4. Security and Permissions
- FAT32 Limitation: FAT32 does not support file permissions or encryption, which are important for securing sensitive data or for systems that require strict file access control.
- NTFS Advantage: NTFS supports file-level security through access control lists (ACLs) and file encryption. This can be crucial if the USB drive is being used in a professional environment or contains sensitive information that needs protection.
5. Stability and Performance
- FAT32 Issues: FAT32 can be less stable with larger drives and more prone to corruption compared to NTFS, especially on drives with heavy usage.
- NTFS Stability: NTFS is more robust and less prone to file system corruption, making it a better choice for USB drives that will see frequent use, especially with large files or complex directory structures.
