What affects the cluster size?

Question

Iron

I tried to find information on the Internet about what effect its size has and which one is better to choose in a particular situation and found nothing.
Tell me, what affects the size of the cluster?

Answer 1

A cluster is the minimum addressable storage unit of information on a disk.
Affects disk performance and read speed.
In most situations, 4 kilobytes is considered optimal.
To say which size is optimal in a particular situation, you need to know this situation.

Answer 2

The larger the files, the larger the cluster, if the files are significantly larger than four x kilobytes, then take four to the cluster, the gain in the metadata file system will be less.

Answer 3

on IOPS.
