What does exFAT mean on external hard drive
EXtended File Allocation Table
(EXtended File Allocation Table) An enhanced version of the FAT file system from Microsoft that was introduced in 2006 with Windows CE and Windows Vista (SP1). exFAT extends the maximum Windows file size from 4GB (FAT32) to virtually unlimited.
What does exFAT stand for
Extensible File Allocation Table
exFAT stands for Extensible File Allocation Table. This file system is introduced by Microsoft in 2006 and optimized for SD cards and USB drives. It has been adopted by the SD Association as the default file system for SDXC cards larger than 32 GB.
What are the features of exFAT
Enable very large files and storage devices. The exFAT file system uses 64 bits to describe file size, thereby enabling applications which depend on very large files. The exFAT file system also allows for clusters as large as 32MB, effectively enabling very large storage devices.
What is exFAT partition
exFAT is optimized for flash drives—designed to be a lightweight file system like FAT32, but without the extra features and overhead of NTFS and without the limitations of FAT32. The name is short for “Extended File Allocation Table.”
Does exFAT have a size limit
It supports huge file stored that is much larger than the 4GB limit imposed by FAT32. If you're curious, the theoretical file size limit is 16 exbibytes, but this exceeds the maximum partition dimension, so the actual size limit of a file stored on exFAT is the same as the partition limit: 128 pebibytes.
Is exFAT faster than NTFS
Yes, exFAT is slower than NTFS. exFAT as a responsive speed for small files and a 15MB/s write speed for large files. NTFS is very slow for small files but the fastest with 25MB/s speed for large files.
What is the maximum size of exFAT partition
exFAT file system works with all versions of Windows, Mac OS X, needs additional software on Linux. It is read-only with Mac and some version of Linux. Maximum file size 4 GB and partition size 8 TB. It also does not have any particular file size or partition size limits.
What is the limit of exFAT
exFAT
| Structures | |
|---|---|
| Max volume size | 128 PB, 512 TB recommended |
| Max file size | 128 PB |
| Max no. of files | up to 2,796,202 per directory |
| Max filename length | 255 characters |
Is exFAT better than NTFS
Conclusion. In a debate regarding exFAT vs NTFS vs FAT32, NTFS is the best format for storage devices with Windows operating system. However, exFAT is best for portable storage devices due to more efficient power and memory management. It also allows you to use a storage device on both Windows and macOS.
Does exFAT limit transfer speed
exFAT allows high read and write speeds. It allows SDXC cards to have a data transfer speed above 10MBps. High speed is possible due to the reduction in the overhead of the file system related to cluster allocation.
Is NTFS slower than exFAT
NTFS is faster as an internal drive file system. It consistently outperforms exFAT efficiency and uses fewer system resources. However, exFAT acts faster when used as the file system for external drives as the read/write speeds are handled differently over USB connections and between operating systems.

exFAT vs. FAT32 Comparison
| Feature | FAT32 | exFAT |
|---|---|---|
| Maximum Volume Size | 8 TB * | 128 PB |
| Maximum File Size | 4 GB | 16 EB |
| Maximum Cluster Size | 32 KB ** | 32 MB |
| Maximum Cluster Count | 228 | 232 |
Is exFAT as fast as NTFS
Yes, exFAT is slower than NTFS. exFAT as a responsive speed for small files and a 15MB/s write speed for large files. NTFS is very slow for small files but the fastest with 25MB/s speed for large files.
