What allocation size should I use for exFAT?
You can safely use 4K allocation unit for exFAT. Even if you have thousands of small files you won’t waste a lot of space. In case of default 128KB allocation unit for e.g. 64GB usb stick, 1024 files of 4K bytes will occupy 128MB instead of 4MB, since every file requires at least one allocation unit.
What is default allocation size for exFAT on Windows 10?
exFAT however only defaults to 4KB in the 7MB–256MB volume range. After that it jumps to 32KB in the 256MB–32GB range, and 128KB beyond that.
What allocation unit size should I use for USB?
If your USB flash drive is smaller than 8GB, the most proper allocation unit size is 4096 bytes. If your flash drive is larger than 8GB but smaller than 16GB, the most proper allocation unit size is 8192 bytes. If your flash drive is larger than 16GB, the most proper allocation unit size is 16 kilobytes.
What allocation unit size should I use for 32GB USB?
Most common would be 512 bytes up to 4kiB (4096 bytes). Though many go with larger as well. You even get some which (at least in part) don’t use allocation units. E.g. the MFT space on a NTFS disk is used for small files (smaller than the allocation unit) and files are stored packed right up against one another.
What is the best allocation size?
If you are a “Standard User” by Microsoft’s definition, you should keep the default 4096 bytes. Basically, the allocation unit size is the block size on your hard drive when it formats NTFS. If you have lots of small files, then it’s a good idea to keep the allocation size small so your harddrive space won’t be wasted.

Which allocation unit size works best?
Does allocation unit size affect speed?
If you make your allocation unit size too small, it can lead to a slower system – allocation will take longer, as there will be more allocation units assigned to each file. If you make your allocation unit size too big, then it will take up precious disk space.
What is allocation unit size exFAT 256gb?
There are default allocation unit sizes for exFAT under different storage capacities: 7MB – 256MB: 4KB. 256MB – 32GB: 32KB. 32GB – 256TB: 128KB. 256TB: Not supported.
Is bigger allocation size better?
In terms of space efficiency, smaller allocation unit sizes perform better. The average space wasted per file will be half the chosen AUS.
Can exFAT transfer large files?
exFAT file system that allows a single file larger than 4GB to be stored on the device. This file system is also compatible with Mac. Windows 7 and Mac OS 10.6. 6 and higher are compatible with exFAT out of the box.
What is allocation unit size exFAT 256GB?

Does exFAT reduce speed?
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.
