EXT4 File System vs. FAT32 File System
What's the Difference?
EXT4 File System and FAT32 File System are both popular file systems used in different operating systems. EXT4 is a modern file system primarily used in Linux operating systems, offering improved performance, reliability, and support for larger file sizes and partitions. On the other hand, FAT32 is an older file system commonly used in Windows and other operating systems due to its compatibility with a wide range of devices. However, FAT32 has limitations such as a maximum file size of 4GB and a maximum partition size of 32GB, which makes it less suitable for modern storage needs. Overall, EXT4 is more advanced and efficient compared to FAT32, but the choice between the two depends on the specific requirements of the user.

Further Detail
Introduction
When it comes to choosing a file system for your storage devices, there are several options available. Two popular choices are the EXT4 and FAT32 file systems. Each has its own set of attributes that make it suitable for different use cases. In this article, we will compare the attributes of EXT4 and FAT32 to help you make an informed decision.
File System Overview
EXT4 is a journaling file system that is commonly used in Linux operating systems. It was designed as an improvement over its predecessor, EXT3, with better performance and reliability. On the other hand, FAT32 is an older file system that is widely supported across different operating systems, including Windows, macOS, and Linux. It is known for its simplicity and compatibility.
File Size Limitations
One of the key differences between EXT4 and FAT32 is the maximum file size they support. EXT4 has a much higher limit, allowing for individual files up to 16 terabytes in size. This makes it ideal for storing large multimedia files or virtual machine images. In contrast, FAT32 has a file size limit of 4 gigabytes, which can be a significant limitation for users dealing with large files.
Partition Size Limitations
In addition to file size limitations, the maximum partition size supported by a file system is also important to consider. EXT4 can handle partitions up to 1 exabyte in size, making it suitable for high-capacity storage devices. On the other hand, FAT32 has a partition size limit of 2 terabytes, which may be insufficient for modern storage requirements.
Performance
When it comes to performance, EXT4 is known for its speed and efficiency. It uses advanced techniques such as delayed allocation and extents to optimize disk usage and minimize fragmentation. This results in faster read and write speeds, especially on large files. In comparison, FAT32 is a simpler file system that may not offer the same level of performance optimization.
Reliability
Reliability is another important factor to consider when choosing a file system. EXT4 is a journaling file system, which means that it keeps a log of changes before they are actually made to the disk. This helps prevent data corruption in case of unexpected shutdowns or system crashes. On the other hand, FAT32 does not have journaling capabilities, making it more susceptible to data loss in such scenarios.
Compatibility
One of the key advantages of FAT32 is its wide compatibility across different operating systems. It is supported natively by Windows, macOS, and Linux, making it a versatile choice for external storage devices that need to be accessed on multiple platforms. EXT4, on the other hand, is primarily used in Linux systems and may require additional software or drivers to be accessed on other operating systems.
Conclusion
In conclusion, both EXT4 and FAT32 have their own strengths and weaknesses. EXT4 is a high-performance file system with support for large files and partitions, making it ideal for modern storage requirements. On the other hand, FAT32 is a simple and widely compatible file system that is suitable for basic storage needs. Ultimately, the choice between EXT4 and FAT32 will depend on your specific use case and requirements.
