How set up allocation unit size? Here is everything you should know!

Here you will find out:

  • what option should you set

Are you ready? Let's read!

When formatting a disk, several logical questions may arise, for example: What exactly should be placed in the selection section when formatting a disk? How do you choose options to customize the allocation unit size, since options range from 512KB to 64KB? Are there any helpful guidelines that can be applied to other types of discs? Maybe you should just leave the default value?

Usually, the default setting is the best choice for most users because of its convenience and ease of use. But, in the choice of format allocation unit size, there are some nuances. Let's look at them.

If you are a regular Microsoft user, don't be smart; just leave the default 4096 bytes. Let's try to explain this opinion: the allocation block size is the block size on your hard disk when formatting NTFS. If there are many small files on the disk, it is recommended to keep the allocation size small to avoid wasting hard disk space. Conversely, if you have a large majority of files, a higher value will increase system performance by reducing the number of blocks to search. At the same time, do not forget that the volumes of modern hard drives are impressive in size and, in fact, does not really matter how to choose the right distribution size. This is precisely why you should not think long, and it is recommended to just leave the default value.

You may also wonder how best to choose the NTFS allocation unit size in terms of space efficiency. It is logical that smaller distribution block sizes work better, and the average space wasted per file is half of the selected AUS (for example, at 4K, 2K is lost per file, and at 64K - 32K). But there is no reason to panic here either, since, as mentioned above, modern drives are huge, and a little wasted space should not be a determining factor in choosing parameters. Naturally, this does not apply to the small SSD.

If your disk is intended for storing media files (here, your photos, music, and videos are stored), then the size of each file is at least 1 MB. In such a case, it is also best to use the Windows default setting for the Windows boot partition, which is 4KB for any NTFS drive smaller than 16TB.
