Why doesn Linux use drive letters?
Drive letters are a legacy limitation carried over from the days before hard disks, when the usual limit on drives was at most four floppies. Linux is more sophisticated than to encumber itself with artificial limitations. It can use as many partitions as required to get the job done. It “mounts” each partition it requires access to to a directory, and can do it after boot if desired, unlike legacy systems that use letters for drive access. The Linux mounting system allows for less downtime, since reboot is not required to add or remove access to a disk or partition other than root.
