Modern disk put more and more of the electronic controls directly on the disk drive itself, leaving relatively little work for the disk controller card to perform.

At the lowest layer are the physical devices, consisting of the magnetic media, motors & controls, and the electronics connected to them and controlling them.

File systems organize storage on disk drives, and can be viewed as a layered design:.

Block sizes may range from 512 bytes to 4K or larger.

Disks are usually accessed in physical blocks, rather than a byte at a time.

Hard disks have two important properties that make them suitable for secondary storage of files in file systems: (1) Blocks of data can be rewritten in place, and (2) they are direct access, allowing any block of data to be accessed with only ( relatively ) minor movements of the disk heads and rotational latency.Abraham Silberschatz, Greg Gagne, and Peter Baer Galvin, "Operating System Concepts, Ninth Edition ", Chapter 12 12.1 File-System Structure.It will be interesting to see what comes of this OpenZFS on Windows support in the future.Operating Systems: File-System Implementation Jorgen Lundman shows off #OpenZFS on Windows, in all its backslashed glory! /eKnD8i2NgD- Bryan Cantrill October 24, 2017 This developer has much of Open ZFS running within Windows as a native kernel module but among the functionality currently missing is ZVOL support, the ability to compile ZFS on top of ZFS, and some remaining bugs as outlined on the aforelinked GitHub repository. Of course, this is an unofficial port and Microsoft has not expressed any interest in bringing ZFS to Windows, especially given their current focus on ReFS. The code for this port is currently in GitHub's lundman/zfsin. OpenZFS contributor Jorgen Lundman has been working on the Windows port of OpenZFS and has it running successfully within a virtual machine. At the OpenZFS Developer Summit today besides an Oracle engineer talked of hope for upstreaming ZFS in Linux, another interesting session was showcasing Open ZFS running under Windows.
