What should I set the allocation unit size to when formatting?
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.
What should I set the allocation unit size to when formatting 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.
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.
What is fast format?

Does allocation unit size affect speed?
Would this actually speed things up? The answer is likely no. So far there haven’t been any real-world examples of larger allocation unit sizes leading to any performance changes on SSDs, even though theoretically this could be the case due to the lower complexity of your file system and faster read-write speeds.
Should I quick format or full format?
If you are planning to re-use the drive and it’s working, a quick format is adequate since you are still the owner. If you believe the drive has problems, a full format is a good option to make sure no issues exist with the drive.
