- The best file system format for a bootable USB or external hard drive is typically ExFAT, which is a cross-platform file system that can be read and written by Windows, macOS, and Linux operating systems. ExFAT is a good choice for bootable drives because it supports large file sizes and is relatively fast. However, if you're using a USB drive with a smaller capacity (less than 4GB), you may want to consider using FAT32 instead, as it's more widely supported by older operating systems.

What is File System
A file system is a way of organizing and storing files on a storage medium, such as a hard disk or CD-ROM, by creating a hierarchical structure of directories and subdirectories, and controlling access to individual files. It allows users to store, retrieve, and manage their data, while also keeping track of who owns each file and managing storage space on the volume. Popular file systems include NTFS, FAT32, exFAT, and EXT2/3/4, each with its own features and benefits, and the right one should be chosen for specific needs.

Four File Systems: NTFS, FAT32, exFAT, and EXT2/3/4
The most common file systems include NTFS, FAT32, exFAT, and EXT 2/3/4, among others.
- NTFS (New Technology File System) is the primary file system used in Windows computers, offering features like hibernation and encryption support, as well as the ability to handle very large files.
- FAT32 is a file system designed for small floppy disks, but remains popular due to its high compatibility with various devices and operating systems.
- exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006, offering advantages over FAT32 but with less widespread support than NTFS or FAT32.
- The EXT file system, designed for Linux operating systems, offers good performance and security through its EXT2, EXT3, and EXT4 variants. However, it is not compatible with Windows or macOS.
The exFAT, FAT32, and NTFS are three different file systems used by Windows operating systems. The main difference between them is the size of the files they can handle.
Which Is The Best File System Format for (Bootable) USB/External Hard Drive
The various file systems in use today each have their own strengths and weaknesses, but exFAT is the most suitable format for USB/external hard drives, offering several advantages over other options.
| NTFS | FAT32 | exFAT | EXT2/3/4 | |
|---|---|---|---|---|
| Compatibility |
|
|
|
|
| Single Volume Size Limit | 8 PB | 8 TB | 128 PB |
EXT2/3 - 32 TiB EXT4 - 1 EiB |
| Individual File Size Limit | 16 EB | 4 GB | 28 PB |
EXT2/3 - 2 TiB EXT4 - 16 TiB |
Compared to NTFS and EXT, exFAT has stronger compatibility, and it also allows for larger file storage compared to FAT32.
Advantages of exFAT:
exFAT has excellent compatibility with all major operating systems, allowing it to be read and written by Windows, macOS, and Linux without any issues.
ExFAT supports bigger files and drives, making it ideal for storing large media files, with the ability to manage up to 64 ZB.
ExFAT is a file system that is easy to use, requiring no special drivers or software, and can be accessed directly from the operating system.
The exFAT file system is highly reliable, making it unlikely to experience data corruption or other issues.
The exFAT file system is the best format for USB and external hard drives due to its compatibility, speed, and reliability. It is widely supported by most operating systems and devices, making it a convenient choice for sharing files.

FAQs
1. Is exFAT a reliable format?
exFAT is a reliable file system format for flash drives, memory cards, and other devices, compatible with Windows, Mac, Xbox One, PS4, Xbox 360, and PS3.
2. Is NTFS good for a flash drive?
NTFS is not ideal for flash drives due to its complexity, which can lead to increased wear and tear on the device. While NTFS was previously necessary to support files larger than 4GB, this is no longer a concern with modern hard drives. As a result, it's generally recommended to format USB drives or SD cards with a simpler file system like FAT32 or exFAT.
3. What are the disadvantages of exFAT?
There are a few disadvantages of exFAT to be aware of.
- Firstly, it is not as widely compatible as FAT32.
- Secondly, exFAT has a larger cluster size than FAT32.
- While exFAT has its advantages, it's not as robust as NTFS in terms of data protection.
Overall, the advantages of exFAT usually outweigh the disadvantages.
4. Why should I not use exFAT?
The exFAT file system is not ideal due to its inefficiency in storing small files, taking up 12% more space than NTFS or FAT32 for a 500KB file, and its limited compatibility with operating systems.
