Storage mount points in a system might be larger or smaller, local or remote, with high or low latency, and various speeds. Storage and network transfer of files is a measurable cost. For example: All subfolders of the /opt directory are mounted as local, low latency, high-throughput drives, with relatively low storage capacity.
