From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For SSD's, it's 100% a logical table, because data is stored all over the place for load balancing purposes, so it already uses a logical table to keep track of what each block is for at any given point in time.
For HDD's, historically they were physically separated, and they mostly are still, but there's still a logical table, and there's no reason the logical table can't say "Blocks 0 through 1234 and 2000 are part of partition 1" if you have something somewhere else that you want on that partition.
